2 DOSAGE AND ADMINISTRATION Administration ( 2.1 ): Always use the enclosed calibrated oral dosing syringe. The calibrated oral syringe measures a maximum SYNDROS dose of 5 mg. If the prescribed dose is greater than 5 mg, the total dose will need to be divided and drawn up in two or more portions using the oral syringe. Take SYNDROS with a full glass of water (6 to 8 ounces). SYNDROS can be administered via silicone enteral feeding tubes. Anorexia Associated with Weight Loss in Adult Patients with AIDS ( 2.2 ): The recommended starting dosage is 2.1 mg orally twice daily, one hour before lunch and dinner. See the full prescribing information for dosage titration to manage adverse reactions and to achieve desired therapeutic effect. Nausea and Vomiting Associated with Chemotherapy in Adult Patients Who Failed Conventional Antiemetics ( 2.3 ): The recommended starting dosage is 4.2 mg/m 2 , administered 1 to 3 hours prior to chemotherapy, then every 2 to 4 hours after chemotherapy for a total of 4 to 6 doses per day. Administer the first dose on an empty stomach at least 30 minutes prior to eating; subsequent doses can be taken without regard to meals. See the full prescribing information for dosage titration to manage adverse reactions and to achieve desired therapeutic effect. 2.1 Important Administration Instructions Oral Administration Always use the enclosed calibrated oral dosing syringe when administering SYNDROS to ensure the dose is measured and administered accurately. The calibrated oral syringe measures a maximum SYNDROS dose of 5 mg. If the prescribed dose is greater than 5 mg, the total dose will need to be divided and drawn up in two or more portions using the oral syringe. Take each dose of SYNDROS with a full glass of water (6 to 8 ounces). For information on dosing SYNDROS with regard to meals, see Dosage and Administration 2.2 and 2.3 . Administration via Feeding Tube (silicone only, greater than or equal to 14 French) SYNDROS can be administered via enteral feeding tubes that are manufactured using silicone, size greater than or equal to 14 French, such as Naso-Gastric (NG), Gastrostomy Tube (G-tube), Percutaneous Endoscopic Gastrostomy tube (PEG-tube) and Gastro-Jejunostomy tube (GJ-tube). Do not use tubes manufactured of polyurethane. Draw up the prescribed dose with the calibrated dosing syringe packaged with SYNDROS. If the prescribed dose is greater than 5 mg, the total dose will need to be divided and drawn up in two or more portions using the oral syringe. Using the calibrated dosing syringe, administer the dose via the feeding tube. Using a catheter-tip syringe, flush the feeding tube with 30 mL of water. 2.2 Anorexia Associated with Weight Loss in Adult Patients with AIDS Starting Dosage The recommended adult starting dosage of SYNDROS is 2.1 mg orally twice daily, one hour before lunch and one hour before dinner. In elderly patients, or patients unable to tolerate 2.1 mg twice daily, consider initiating SYNDROS at 2.1 mg once daily one hour before dinner or at bedtime to reduce the risk of central nervous system (CNS) symptoms [see Use in Specific Populations ( 8.5 ) ]. Dosing later in the day may reduce the frequency of Central Nervous System (CNS) adverse reactions. CNS adverse reactions are dose-related [see Warnings and Precautions ( 5.1 )] ; therefore, monitor patients and reduce the dosage as needed.

ntral nervous system (CNS) symptoms [see Use in Specific Populations ( 8.5 ) ]. Dosing later in the day may reduce the frequency of Central Nervous System (CNS) adverse reactions. CNS adverse reactions are dose-related [see Warnings and Precautions ( 5.1 )] ; therefore, monitor patients and reduce the dosage as needed. If CNS adverse reactions of feeling high, dizziness, confusion, and somnolence occur, they usually resolve in 1 to 3 days and usually do not require dosage reduction. If CNS adverse reactions are severe or persistent, reduce the dosage to 2.1 mg once daily one hour before dinner or in the evening at bedtime. Dosage Titration If tolerated and further therapeutic effect is desired, the dosage may be increased gradually to 2.1 mg one hour before lunch and 4.2 mg one hour before dinner. Increase the dose of SYNDROS gradually in order to reduce the frequency of dose-related adverse reactions [see Warnings and Precautions ( 5.1 )]. Most patients respond to 2.1 mg twice daily, but the dose may be further increased to 4.2 mg one hour before lunch and 4.2 mg one hour before dinner, as tolerated to achieve a therapeutic effect. Maximum Dosage: 8.4 mg twice daily. 2.3 Nausea and Vomiting Associated with Cancer Chemotherapy in Adult Patients Who Failed Conventional Antiemetics Starting Dosage The recommended starting dosage of SYNDROS is 4.2 mg/m 2 orally administered 1 to 3 hours prior to chemotherapy and then every 2 to 4 hours after chemotherapy for a total of 4 to 6 doses per day. Calculate the starting dose by following the steps below: Starting dose (mg) = Patient body surface area (BSA) in m 2 multiplied by 4.2 mg/m 2 Round dose to the nearest 0.1 mg increment Convert from milligrams (mg) to milliliters (mL): Starting dose (mg) rounded to the nearest 0.1 mg increment divided by 5 = Starting dose in milliliters (mL) To correspond with the calibrated oral dosing syringe, the dose may need to be rounded to the nearest 0.1 mL increment. In elderly patients, consider initiating SYNDROS at 2.1 mg/m 2 once daily 1 to 3 hours prior to chemotherapy to reduce the risk of CNS symptoms [see Use in Specific Populations ( 8.5 )] . Because food delays the absorption of SYNDROS, administer the first dose on an empty stomach at least 30 minutes before eating. Subsequent doses can be taken without regard to meals. Because food can substantially change the systemic exposure to dronabinol and its active metabolite, the timing of dosing in relation to meal times should be kept consistent for each chemotherapy cycle, once the dosage has been determined from the titration process. Dosage Titration The dosage can be titrated to clinical response during a chemotherapy cycle or subsequent cycles, based upon initial effect, as tolerated to achieve a clinical effect, in increments of 2.1 mg/m 2 . Maximum Dosage: 12.6 mg/m 2 per dose for 4 to 6 doses per day. Adverse reactions are dose-related and psychiatric symptoms increase significantly at the maximum dosage [see Warnings and Precautions ( 5.1 )] . Monitor patients for adverse reactions and consider decreasing the dose to 2.1 mg once daily 1 to 3 hours prior to chemotherapy to reduce the risk of CNS adverse reactions.

5 WARNINGS AND PRECAUTIONS Neuropsychiatric Adverse Reactions : May cause psychiatric and cognitive effects and impair mental and/or physical abilities. Avoid use in patients with a psychiatric history. Monitor for symptoms and avoid concomitant use of drugs with similar effects. Inform patients not to operate motor vehicles or other dangerous machinery until they are reasonably certain that SYNDROS does not affect them adversely. ( 5.1 ) Hemodynamic Instability : Patients with cardiac disorders may experience hypotension, hypertension, syncope, or tachycardia. Avoid concomitant use of drugs with similar effects and monitor for hemodynamic changes after initiating or increasing the dosage of SYNDROS. ( 5.2 ) Interaction with Disulfiram and Metronidazole : May cause disulfiram-like reaction. Discontinue products containing disulfiram or metronidazole at least 14 days before and do not administer 7 days after treatment with SYNDROS. ( 4 , 5.3 , 7.1 ) Seizures and Seizure-like Activity : Weigh the potential risk versus benefits before prescribing SYNDROS to patients with a history of seizures, including those requiring anti-epileptic medication or with other factors that lower the seizure threshold. Monitor patients and discontinue if seizures occur. ( 5.4 ) Multiple Substance Abuse : Assess risk for abuse or misuse in patients with a history of substance abuse or dependence, prior to prescribing SYNDROS and monitor for the development of associated behaviors or conditions. ( 5.5 ) Paradoxical Nausea, Vomiting, or Abdominal Pain : Consider dose reduction or discontinuation, if worsening of symptoms while on treatment. ( 5.6 ) Toxicities Related to Propylene Glycol in Preterm Neonates : The safety and effectiveness of SYNDROS have not been established in pediatric patients. Avoid use in preterm neonates in the immediate postnatal period. ( 5.7 ) 5.1 Neuropsychiatric Adverse Reactions Psychiatric Adverse Reactions Dronabinol has been reported to exacerbate mania, depression, or schizophrenia. Prior to initiating treatment with SYNDROS, screen patients for a history of these illnesses. Avoid use in patients with a psychiatric history or, if the drug cannot be avoided, monitor patients for new or worsening psychiatric symptoms during treatment. Also, avoid concomitant use with other drugs that are associated with similar psychiatric effects. Cognitive Adverse Reactions Use of SYNDROS has been associated with cognitive impairment and altered mental state. Reduce the dose of SYNDROS or discontinue use of SYNDROS if signs or symptoms of cognitive impairment develop. Elderly and pediatric patients may be more sensitive to the neurological and psychoactive effects of SYNDROS [see Use in Specific Populations ( 8.4 , 8.5 )] . Hazardous Activities SYNDROS can cause and may impair the mental and/or physical abilities required for the performance of hazardous tasks such as driving a motor vehicle or operating machinery. Concomitant use of other drugs that cause dizziness, confusion, sedation, or somnolence such as CNS depressants may increase this effect (e.g., barbiturates, benzodiazepines, lithium, opioids, buspirone, scopolamine, antihistamines, tricyclic antidepressants, other anticholinergic agents, and muscle relaxants). Inform patients not to operate motor vehicles or other dangerous machinery until they are reasonably certain that SYNDROS does not affect them adversely.

rbiturates, benzodiazepines, lithium, opioids, buspirone, scopolamine, antihistamines, tricyclic antidepressants, other anticholinergic agents, and muscle relaxants). Inform patients not to operate motor vehicles or other dangerous machinery until they are reasonably certain that SYNDROS does not affect them adversely. 5.2 Hemodynamic Instability Patients may experience occasional hypotension, possible hypertension, syncope, or tachycardia while taking SYNDROS [see Clinical Pharmacology ( 12.2 )] . Patients with cardiac disorders may be at higher risk. Avoid concomitant use of other drugs that are also associated with similar cardiac effects (e.g., amphetamines, other sympathomimetic agents, atropine, amoxapine, scopolamine, antihistamines, other anticholinergic agents, amitriptyline, desipramine, other tricyclic antidepressants). Monitor patients for changes in blood pressure, heart rate, and syncope after initiating or increasing the dosage of SYNDROS. 5.3 Interaction with Disulfiram and Metronidazole SYNDROS contains 50% (w/w) dehydrated alcohol and 5.5% (w/w) propylene glycol. Use of SYNDROS may cause a disulfiram-like reaction, characterized by abdominal cramps, nausea, vomiting, headaches, and flushing, in patients receiving disulfiram or other drugs that produce this reaction (e.g., metronidazole). Discontinue products containing disulfiram or metronidazole at least 14 days before starting treatment with SYNDROS and do not administer these products within 7 days of completing treatment with SYNDROS [see Contraindications ( 4 ), Drug Interactions ( 7.3 )] . When administered concomitantly with propylene glycol, ethanol competitively inhibits the metabolism of propylene glycol, which may lead to elevated concentrations of propylene glycol. However, the contribution of propylene glycol, if any, to the interaction between disulfiram and SYNDROS is unknown. 5.4 Seizures Seizures and seizure-like activity have been reported in patients receiving dronabinol. Weigh this potential risk against the benefits before prescribing SYNDROS to patients with a history of seizures, including those receiving anti-epileptic medication or with other factors that can lower the seizure threshold. Monitor patients with a history of seizure disorders for worsened seizure control during SYNDROS therapy. If a seizure occurs, advise patients to discontinue SYNDROS and contact a healthcare provider immediately. 5.5 Multiple Substance Abuse Patients with a history of substance abuse or dependence, including marijuana or alcohol, may be more likely to abuse SYNDROS as well. SYNDROS contains 50% (w/w) dehydrated alcohol. Assess each patient’s risk for abuse or misuse prior to prescribing SYNDROS and monitor patients with a history of substance abuse during treatment with SYNDROS for the development of these behaviors or conditions. 5.6 Paradoxical Nausea, Vomiting, or Abdominal Pain New or worsening nausea, vomiting, or abdominal pain can occur during treatment with synthetic delta-9 tetrahydrocannabinol (delta-9-THC), the active ingredient in SYNDROS. In some cases, these adverse reactions were severe (e.g., dehydration, electrolyte abnormalities) and required dose reduction or drug discontinuation. Symptoms are similar to cannabinoid hyperemesis syndrome (CHS), which is described as cyclical events of abdominal pain, nausea, and vomiting in chronic, long-term users of delta-9-THC products. Because patients may not recognize these symptoms as abnormal, it is important to specifically ask patients or their caregivers about the development or worsening of nausea, vomiting, or abdominal pain while being treated with SYNDROS. Consider dose reduction or discontinuing SYNDROS if a patient develops worsening nausea, vomiting, or abdominal pain while on treatment.

abnormal, it is important to specifically ask patients or their caregivers about the development or worsening of nausea, vomiting, or abdominal pain while being treated with SYNDROS. Consider dose reduction or discontinuing SYNDROS if a patient develops worsening nausea, vomiting, or abdominal pain while on treatment. 5.7 Toxicity in Preterm Neonates SYNDROS contains the excipients dehydrated alcohol (50%, w/w) and propylene glycol (5.5%, w/w). When administered concomitantly with propylene glycol, ethanol competitively inhibits the metabolism of propylene glycol, which may lead to elevated concentrations of propylene glycol. Preterm neonates may be at increased risk of propylene glycol-associated adverse reactions due to a diminished ability to metabolize propylene glycol, thereby, leading to accumulation. The safety and effectiveness of SYNDROS have not been established in pediatric patients. Avoid SYNDROS in preterm neonates in the immediate postnatal period because of possible propylene glycol-associated toxicities including: hyperosmolarity, with or without lactic acidosis, renal toxicity, CNS depression (including stupor, coma, and apnea), seizures, hypotonia, cardiac arrhythmias, electrocardiogram (ECG) changes, and hemolysis.

6 ADVERSE REACTIONS Most common adverse reactions (≥3%) are: abdominal pain, dizziness, euphoria, nausea, paranoid reaction, somnolence, thinking abnormal, and vomiting. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Benuvia Operations, LLC at 1-844-558-8289 or FDA at MedWatch phone number 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The following serious adverse reactions are described below and elsewhere in the labeling. Neuropsychiatric Adverse Reactions [see Warnings and Precautions ( 5.1 )] Hemodynamic Instability [see Warnings and Precautions ( 5.2 )] Seizures [see Warnings and Precautions ( 5.4 )] Paradoxical Nausea, Vomiting, and Abdominal Pain [see Warnings and Precautions ( 5.6 )] Toxicity in Preterm Neonates [see Warnings and Precautions ( 5.7 )] The safety of SYNDROS has been established based on studies of dronabinol capsules. Studies of AIDS-related weight loss included 157 patients receiving dronabinol capsules and 67 receiving placebo. Studies of nausea and vomiting related to cancer chemotherapy included 317 patients receiving dronabinol capsules and 68 receiving placebo. In the tables below is a summary of the adverse reactions in 474 patients exposed to dronabinol capsules in studies. Studies of different durations were combined by considering the first occurrence of adverse reactions during the first 28 days. A cannabinoid dose-related “high” (easy laughing, elation and heightened awareness) has been reported by patients receiving dronabinol capsules in both the antiemetic (24%) and the lower dose appetite stimulant clinical trials (8%). The most frequently reported adverse experiences in patients with AIDS during placebo-controlled clinical trials involved the CNS and were reported by 33% of patients receiving dronabinol capsules. About 25% of patients reported a CNS adverse reaction during the first 2 weeks and about 4% reported such a reaction each week for the next 6 weeks thereafter. Common Adverse Reactions The following adverse reactions were reported in clinical trials of dronabinol capsules at an incidence greater than 1%. *Actual Incidence 3% to 10% System Organ Class Adverse Reactions General Asthenia Cardiovascular Palpitations, tachycardia, vasodilation/facial flush Gastrointestinal Abdominal pain*, nausea*, vomiting* Central Nervous System Dizziness*, euphoria*, paranoid reaction*, somnolence*, thinking abnormal*, amnesia, anxiety/nervousness, ataxia, confusion, depersonalization, hallucination Less Common Adverse Reactions The following adverse reactions were reported in clinical trials of dronabinol capsules at an incidence less than or equal to 1%.

7 DRUG INTERACTIONS Inhibitors and Inducers of CYP2C9 and CYP3A4 : May alter dronabinol systemic exposure; monitor for dronabinol-related adverse reactions or loss of efficacy. ( 7.2 ) Highly Protein-Bound Drugs : Potential for displacement of other drugs from plasma proteins; monitor for adverse reactions to concomitant narrow therapeutic index drugs (e.g., warfarin, cyclosporine, or amphotericin B) when initiating or increasing the dosage of SYNDROS. ( 7.3 ) 7.1 Disulfiram and Metronidazole SYNDROS contains 50% (w/w) dehydrated alcohol and 5.5% (w/w) propylene glycol, which can produce disulfiram-like reactions when co-administered with disulfiram or other drugs that produce this reaction (e.g., metronidazole). Discontinue products containing disulfiram or metronidazole at least 14 days before starting treatment with SYNDROS and do not administer these products within 7 days of completing treatment with SYNDROS [see Contraindications ( 4 ), Warnings and Precautions ( 5.3 )] . When administered concomitantly with propylene glycol, ethanol competitively inhibits the metabolism of propylene glycol, which may lead to elevated concentrations of propylene glycol. However, the contribution of propylene glycol, if any, to the interaction between disulfiram and SYNDROS is unknown. 7.2 Effect of Other Drugs on Dronabinol Dronabinol is primarily metabolized by CYP2C9 and CYP3A4 enzymes. Inhibitors of these enzymes may increase, while inducers may decrease, the systemic exposure of dronabinol and/or its active metabolite resulting in an increase in dronabinol-related adverse reactions or loss of efficacy of SYNDROS. Monitor for increased dronabinol-related adverse reactions when SYNDROS is co-administered with inhibitors of CYP2C9 (e.g., amiodarone, fluconazole) and inhibitors of CYP3A4 enzymes (e.g., ketoconazole, itraconazole, clarithromycin, ritonavir, erythromycin, grapefruit juice). 7.3 Highly Protein-Bound Drugs Dronabinol is highly bound to plasma proteins, and therefore, might displace and increase the free fraction of other concomitantly administered protein-bound drugs. Although this displacement has not been confirmed in vivo, monitor patients for increased adverse reactions to narrow therapeutic index drugs (e.g., warfarin, cyclosporine, amphotericin B) when initiating treatment or increasing the dosage of SYNDROS.

8 USE IN SPECIFIC POPULATIONS Pregnancy : May cause fetal harm. ( 8.1 ) Lactation : Advise HIV infected women not to breastfeed due to the potential for HIV transmission. ( 8.2 ) Geriatric Use: Elderly patients may be more sensitive to the neuropsychiatric and postural hypotensive effects. Consider a lower starting dose in elderly patients. ( 2.2 , 2.3 , 5.1 , 5.2 , 8.5 ) 8.1 Pregnancy Risk Summary SYNDROS, a synthetic cannabinoid containing alcohol, may cause fetal harm. Avoid use of SYNDROS in pregnant women. Although there is little published data on the use of synthetic cannabinoids during pregnancy, use of cannabis (e.g., marijuana) and use of alcohol during pregnancy have been associated with adverse fetal/neonatal outcomes (see Clinical Considerations ) . Cannabinoids have been found in the umbilical cord blood from pregnant women who smoke cannabis. In animal reproduction studies, no teratogenicity was reported in mice administered dronabinol (delta-9-THC) at up to 30 times the MRHD (maximum recommended human doses) and up to 5 times the MRHD for patients with AIDS and cancer, respectively. Similar findings were reported in pregnant rats administered dronabinol at up to 5 to 20 times the MRHD and 3 times the MRHD for patients with AIDS and cancer, respectively. Decreased maternal weight gain and number of viable pups and increased fetal mortality and early resorptions were observed in both species at doses which induced maternal toxicity. In rats, maternal administration of dronabinol from pregnancy (implantation) through weaning was associated with maternal toxicity, including mortality of pups, and adverse developmental and neurodevelopmental effects on the pups at 2 to 20 times the MRHD for patients with AIDS and less than and up to 3.3 times the MRHD for patients with cancer. (see Data ) . The estimated background risk of major birth defects and miscarriage for the indicated populations are unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Fetal/Neonatal Adverse Reactions Published studies suggest that during pregnancy, the use of cannabis, which includes THC, whether for recreational or medicinal purposes, may increase the risk of adverse fetal/neonatal outcomes including fetal growth restriction, low birth weight, preterm birth, small-for-gestational age, admission to the neonatal intensive care unit, and stillbirth. Therefore, use of cannabis during pregnancy should be avoided. SYNDROS contains alcohol. Published studies have demonstrated that alcohol is associated with fetal harm including central nervous system abnormalities, behavioral disorders, and impaired intellectual development. Avoid use of SYNDROS in pregnant women. Data Human Data Delta-9-THC has been measured in the cord blood of some infants whose mothers reported prenatal use of cannabis, suggesting that dronabinol may cross the placenta to the fetus during pregnancy. The effects of delta-9-THC on the fetus are not known. Animal Data The recommended dose ranges for SYNDROS in patients with AIDS and patients with cancer are designed to achieve the same systemic exposure ranges to delta-9-THC as with the recommended dose ranges for dronabinol capsules.

a to the fetus during pregnancy. The effects of delta-9-THC on the fetus are not known. Animal Data The recommended dose ranges for SYNDROS in patients with AIDS and patients with cancer are designed to achieve the same systemic exposure ranges to delta-9-THC as with the recommended dose ranges for dronabinol capsules. Therefore, animal to human dose multiples, as shown below, are based on the MRHDs (maximum recommended human doses) for dronabinol capsules, instead of the MRHDs for SYNDROS, which are 15% lower. This approach for dose comparison between animals and humans is supported by the demonstrated difference in dronabinol bioavailability between SYNDROS and dronabinol capsules. Reproduction studies with dronabinol have been performed in mice at 15 to 450 mg/m 2 , equivalent to 1 to 30 times the MRHD of 15 mg/m 2 /day (dronabinol capsules) in patients with AIDS or 0.2 to 5 times the MRHD of 90 mg/m 2 /day (dronabinol capsules) in patients with cancer, and in rats at 74 to 295 mg/m 2 (equivalent to 5 to 20 times the MRHD of 15 mg/m 2 /day in patients with AIDS or 0.8 to 3 times the MRHD of 90 mg/m 2 /day in patients with cancer). These studies have revealed no evidence of teratogenicity due to delta-9-THC. At these dronabinol dosages in mice and rats, delta-9-THC decreased maternal weight gain and number of viable pups and increased fetal mortality and early resorptions. Such effects were dose dependent and less apparent at lower doses that produced less maternal toxicity. Review of published literature indicates that the endocannabinoid system plays a role in neurodevelopmental processes such as neurogenesis, migration, and synaptogenesis. Exposure of pregnant rats to delta-9-THC (during and after organogenesis) may modulate these processes to result in abnormal patterns of neuronal connectivity and subsequent cognitive impairments in the offspring. Nonclinical toxicity studies in pregnant rats and newborn pups have shown prenatal exposure to delta-9-THC that resulted in impairment of motor function, alteration in synaptic activity, and interference in cortical projection of neuron development in the offspring. Prenatal exposure has shown effects on cognitive function such as learning, short- and long-term memory, attention, decreased ability to remember task, and ability to discriminate between novel and same objects. Overall, prenatal exposure to delta-9-THC has resulted in significant and long-term changes in brain development, cognition, and behavior in rat offspring. In a pre- and post-natal developmental study, female rats administered dronabinol by oral gavage in a vehicle of medium chain triglycerides at doses of 5, 25 and 50 mg/kg/day (equivalent to 1.7, 10, and 20 times the MRHD for patients with AIDS and 0.33, 1.7, and 3.3 times the MRHD for patients with cancer, respectively, based on body surface area) from gestation day 6 (implantation) through lactation day 20 (weaning). Maternal toxicity caused mortality of pups at and above 10 times the MRHD for patients with AIDS and 1.7 times the MRHD for patients with cancer. At 20 times the MRHD for patients with AIDS and 3.3 times the MRHD for patients with cancer, treatment with dronabinol was associated with an increase in the number of dams with 100% pup mortality on lactation days 1 to 4. At 2 and 10 times the MRHD for patients with AIDS and 0.33 and 1.7 times the MRHD for patients with cancer, dronabinol produced adverse effects on the offspring including delays in developmental landmark parameters (e.g., surface righting reflex, negative geotaxis, and air righting reflex), decreased fertility and pregnancy index, reduced ovary and uterus weights, decreased implantations and viable embryos, and increased post-implantation loss.

adverse effects on the offspring including delays in developmental landmark parameters (e.g., surface righting reflex, negative geotaxis, and air righting reflex), decreased fertility and pregnancy index, reduced ovary and uterus weights, decreased implantations and viable embryos, and increased post-implantation loss. Neurological adverse effects such as piloerection, landing foot splay and an increase in the number of rears in open field were observed in offspring at 10 and 20 times the MRHD for patients with AIDS and 0.33 and 1.7 times the MRHD for patients with cancer. Administration of dronabinol in 50% ethanol (used in the vehicle for SYNDOS), was poorly tolerated in maternal animals. Serious adverse signs of toxicity were observed in the control group (vehicle only) and in dronabinol-containing dose groups at 10 and 20 times the MRHD for patients with AIDS and 1.7 and 3.3 times the MRHD for patients with cancer, resulting in termination of all animals at the 50 mg/kg dose level prior to delivery of litters. These animal findings are difficult to interpret due to effects of alcohol in the vehicle. 8.2 Lactation Risk Summary For mothers infected with the Human Immunodeficiency Virus (HIV), the Centers for Disease Control and Prevention recommend that HIV-infected mothers not breastfeed their infants to avoid risking postnatal transmission of HIV. Because of the potential for HIV transmission (in HIV-negative infants) and serious adverse reactions in a breastfed infant, instruct mothers not to breastfeed if they are receiving SYNDROS. For mothers with nausea and vomiting associated with cancer chemotherapy, there are limited data on the presence of dronabinol in human milk, the effects on the breastfed infant, or the effects on milk production. The reported effects of inhaled cannabis transferred to the breastfeeding infant have been inconsistent and insufficient to establish causality. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for SYNDROS and any potential adverse effects on the breastfed infant from SYNDROS or from the underlying maternal condition. 8.4 Pediatric Use The safety and effectiveness of SYNDROS have not been established in pediatric patients. Pediatric patients may be more sensitive to neurological and psychoactive effects of SYNDROS [see Warnings and Precautions ( 5.1 )] . SYNDROS contains the excipients 50% (w/w) dehydrated alcohol and 5.5% (w/w) propylene glycol. Ethanol competitively inhibits the metabolism of propylene glycol, which may lead to elevated concentrations of propylene glycol. Preterm neonates may be at increased risk of propylene glycol-associated adverse events due to diminished ability to metabolize propylene glycol, thereby, leading to accumulation [see Warnings and Precautions ( 5.7 )] . 8.5 Geriatric Use Clinical studies of dronabinol capsules in AIDS and cancer patients did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Elderly patients may be more sensitive to the neuropsychiatric and postural hypotensive effects of SYNDROS [see Warnings and Precautions ( 5.1 , 5.2 )] . Elderly patients with dementia are at increased risk for falls as a result of their underlying disease state, which may be exacerbated by the CNS effects of somnolence and dizziness associated with SYNDROS [see Warnings and Precautions ( 5.1 )] . These patients should be monitored closely and placed on fall precautions prior to initiating SYNDROS therapy. In antiemetic studies, no difference in efficacy was apparent in patients greater than 55 years of age compared to younger patients.

In antiemetic studies, no difference in efficacy was apparent in patients greater than 55 years of age compared to younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of falls, decreased hepatic, renal, or cardiac function, increased sensitivity to psychoactive effects, and of concomitant disease or other drug therapy [see Dosage and Administration ( 2.2 , 2.3 )] . 8.6 Effect of CYP2C9 Polymorphism Published data suggest that systemic clearance of dronabinol may be reduced and concentrations may be increased in presence of CYP2C9 genetic polymorphism. Monitoring for increased adverse reactions is recommended in patients known to carry genetic variants associated with diminished CYP2C9 function [see Clinical Pharmacology ( 12.5 )] .

8.1 Pregnancy Risk Summary SYNDROS, a synthetic cannabinoid containing alcohol, may cause fetal harm. Avoid use of SYNDROS in pregnant women. Although there is little published data on the use of synthetic cannabinoids during pregnancy, use of cannabis (e.g., marijuana) and use of alcohol during pregnancy have been associated with adverse fetal/neonatal outcomes (see Clinical Considerations ) . Cannabinoids have been found in the umbilical cord blood from pregnant women who smoke cannabis. In animal reproduction studies, no teratogenicity was reported in mice administered dronabinol (delta-9-THC) at up to 30 times the MRHD (maximum recommended human doses) and up to 5 times the MRHD for patients with AIDS and cancer, respectively. Similar findings were reported in pregnant rats administered dronabinol at up to 5 to 20 times the MRHD and 3 times the MRHD for patients with AIDS and cancer, respectively. Decreased maternal weight gain and number of viable pups and increased fetal mortality and early resorptions were observed in both species at doses which induced maternal toxicity. In rats, maternal administration of dronabinol from pregnancy (implantation) through weaning was associated with maternal toxicity, including mortality of pups, and adverse developmental and neurodevelopmental effects on the pups at 2 to 20 times the MRHD for patients with AIDS and less than and up to 3.3 times the MRHD for patients with cancer. (see Data ) . The estimated background risk of major birth defects and miscarriage for the indicated populations are unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Fetal/Neonatal Adverse Reactions Published studies suggest that during pregnancy, the use of cannabis, which includes THC, whether for recreational or medicinal purposes, may increase the risk of adverse fetal/neonatal outcomes including fetal growth restriction, low birth weight, preterm birth, small-for-gestational age, admission to the neonatal intensive care unit, and stillbirth. Therefore, use of cannabis during pregnancy should be avoided. SYNDROS contains alcohol. Published studies have demonstrated that alcohol is associated with fetal harm including central nervous system abnormalities, behavioral disorders, and impaired intellectual development. Avoid use of SYNDROS in pregnant women. Data Human Data Delta-9-THC has been measured in the cord blood of some infants whose mothers reported prenatal use of cannabis, suggesting that dronabinol may cross the placenta to the fetus during pregnancy. The effects of delta-9-THC on the fetus are not known. Animal Data The recommended dose ranges for SYNDROS in patients with AIDS and patients with cancer are designed to achieve the same systemic exposure ranges to delta-9-THC as with the recommended dose ranges for dronabinol capsules. Therefore, animal to human dose multiples, as shown below, are based on the MRHDs (maximum recommended human doses) for dronabinol capsules, instead of the MRHDs for SYNDROS, which are 15% lower. This approach for dose comparison between animals and humans is supported by the demonstrated difference in dronabinol bioavailability between SYNDROS and dronabinol capsules.

below, are based on the MRHDs (maximum recommended human doses) for dronabinol capsules, instead of the MRHDs for SYNDROS, which are 15% lower. This approach for dose comparison between animals and humans is supported by the demonstrated difference in dronabinol bioavailability between SYNDROS and dronabinol capsules. Reproduction studies with dronabinol have been performed in mice at 15 to 450 mg/m 2 , equivalent to 1 to 30 times the MRHD of 15 mg/m 2 /day (dronabinol capsules) in patients with AIDS or 0.2 to 5 times the MRHD of 90 mg/m 2 /day (dronabinol capsules) in patients with cancer, and in rats at 74 to 295 mg/m 2 (equivalent to 5 to 20 times the MRHD of 15 mg/m 2 /day in patients with AIDS or 0.8 to 3 times the MRHD of 90 mg/m 2 /day in patients with cancer). These studies have revealed no evidence of teratogenicity due to delta-9-THC. At these dronabinol dosages in mice and rats, delta-9-THC decreased maternal weight gain and number of viable pups and increased fetal mortality and early resorptions. Such effects were dose dependent and less apparent at lower doses that produced less maternal toxicity. Review of published literature indicates that the endocannabinoid system plays a role in neurodevelopmental processes such as neurogenesis, migration, and synaptogenesis. Exposure of pregnant rats to delta-9-THC (during and after organogenesis) may modulate these processes to result in abnormal patterns of neuronal connectivity and subsequent cognitive impairments in the offspring. Nonclinical toxicity studies in pregnant rats and newborn pups have shown prenatal exposure to delta-9-THC that resulted in impairment of motor function, alteration in synaptic activity, and interference in cortical projection of neuron development in the offspring. Prenatal exposure has shown effects on cognitive function such as learning, short- and long-term memory, attention, decreased ability to remember task, and ability to discriminate between novel and same objects. Overall, prenatal exposure to delta-9-THC has resulted in significant and long-term changes in brain development, cognition, and behavior in rat offspring. In a pre- and post-natal developmental study, female rats administered dronabinol by oral gavage in a vehicle of medium chain triglycerides at doses of 5, 25 and 50 mg/kg/day (equivalent to 1.7, 10, and 20 times the MRHD for patients with AIDS and 0.33, 1.7, and 3.3 times the MRHD for patients with cancer, respectively, based on body surface area) from gestation day 6 (implantation) through lactation day 20 (weaning). Maternal toxicity caused mortality of pups at and above 10 times the MRHD for patients with AIDS and 1.7 times the MRHD for patients with cancer. At 20 times the MRHD for patients with AIDS and 3.3 times the MRHD for patients with cancer, treatment with dronabinol was associated with an increase in the number of dams with 100% pup mortality on lactation days 1 to 4. At 2 and 10 times the MRHD for patients with AIDS and 0.33 and 1.7 times the MRHD for patients with cancer, dronabinol produced adverse effects on the offspring including delays in developmental landmark parameters (e.g., surface righting reflex, negative geotaxis, and air righting reflex), decreased fertility and pregnancy index, reduced ovary and uterus weights, decreased implantations and viable embryos, and increased post-implantation loss.

9 DRUG ABUSE AND DEPENDENCE 9.1 Controlled Substance SYNDROS contains dronabinol oral solution, a Schedule II controlled substance. 9.2 Abuse SYNDROS contains dronabinol, the main psychoactive component in marijuana. Ingestion of high doses of dronabinol increases the risk of psychiatric adverse reactions if abused or misused, while continued administration can lead to addiction. Psychiatric adverse reactions may include psychosis, hallucinations, depersonalization, mood alteration, and paranoia. In vitro studies demonstrate that SYNDROS can be easily and effectively abused without manipulation. SYNDROS contains 50% (w/w) dehydrated alcohol [see Warning and Precautions ( 5.5 )] . In a randomized, single-dose, double-blind, placebo- and active-controlled crossover pharmacodynamic study of 43 experienced marijuana smokers, “drug liking” responses and safety of SYNDROS were compared with placebo and dronabinol in sesame oil oral capsules. Treatment arms were 10 mg and 30 mg dronabinol capsules, 10 mg and 30 mg dronabinol from SYNDROS, and placebo oral solution and capsules. Greater “drug liking” scores were reported with the 30 mg dose, compared with the 10 mg dose, for both SYNDROS and dronabinol-containing capsules. Overall, the pharmacodynamic results from this study demonstrated no statistically significant differences in various measures of drug liking for the doses taken, though the SYNDROS results were consistently greater than those of dronabinol capsules. Similarly, observed adverse reactions were greater for SYNDROS. The pharmacodynamic and safety effects of SYNDROS following multiple doses have not been evaluated. Patients should be instructed to keep SYNDROS in a secure place out of reach of others for whom the medication has not been prescribed. 9.3 Dependence Physical dependence is a state that develops as a result of physiological adaptation in response to repeated drug use. Physical dependence manifests by drug class-specific withdrawal symptoms after abrupt discontinuation or a significant dose reduction of a drug. The appearance of a withdrawal syndrome when administration of the drug is terminated is the only actual evidence of physical dependence. Physical dependence can develop during chronic therapy with SYNDROS and develops after chronic abuse of marijuana. A withdrawal syndrome was reported after the abrupt discontinuation of dronabinol capsules in subjects receiving dosages of 210 mg per day for 12 to 16 consecutive days. Within 12 hours after discontinuation, subjects manifested symptoms such as irritability, insomnia, and restlessness. By approximately 24 hours post-dronabinol discontinuation, withdrawal symptoms intensified to include “hot flashes”, sweating, rhinorrhea, loose stools, hiccoughs, and anorexia. These withdrawal symptoms gradually dissipated over the next 48 hours. Electroencephalographic changes consistent with the effects of drug withdrawal (hyperexcitation) were recorded in patients after abrupt dechallenge. Patients also complained of disturbed sleep for several weeks after discontinuing therapy with high dosages of dronabinol.

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Dronabinol is an orally active cannabinoid that has complex effects on the CNS, including central sympathomimetic activity. Cannabinoid receptors have been discovered in neural tissues. These receptors may play a role in mediating the effects of dronabinol. 12.2 Pharmacodynamics Effects on the Cardiovascular System Dronabinol-induced sympathomimetic activity may result in tachycardia and/or conjunctival injection. Its effects on blood pressure are inconsistent, but subjects have experienced orthostatic hypotension and/or syncope upon abrupt standing [see Warnings and Precautions ( 5.2 )] . Effects on the Central Nervous System Dronabinol also demonstrates reversible effects on appetite, mood, cognition, memory, and perception. These phenomena appear to be dose-related, increasing in frequency with higher dosages, and subject to great inter-patient variability. After oral administration, dronabinol capsules have an onset of action of approximately 0.5 to 1 hours and peak effect at 2 to 4 hours. Duration of action for psychoactive effects is 4 to 6 hours, but the appetite stimulant effect of dronabinol may continue for 24 hours or longer after administration. Tachyphylaxis and tolerance develop to some of the cardiovascular and CNS pharmacologic effects of dronabinol with chronic use, suggesting an indirect effect on sympathetic neurons. In a study of the pharmacodynamics of chronic dronabinol exposure, healthy male subjects (N = 12) received 12 times the maximum dose for anorexia associated with weight loss in patients with AIDS of dronabinol capsules in divided doses for 16 days. An initial tachycardia induced by dronabinol was replaced successively by normal sinus rhythm and then bradycardia. A decrease in supine blood pressure, made worse by standing, was also observed initially. These subjects developed tolerance to the cardiovascular and subjective adverse CNS effects of dronabinol within 12 days of treatment initiation. Tachyphylaxis and tolerance do not appear to develop to the appetite stimulant effect of dronabinol. In clinical studies of dronabinol capsules in AIDS patients, at the recommended dosage, the appetite stimulant effect was sustained for up to five months. 12.3 Pharmacokinetics Absorption Dronabinol (delta-9-THC) is almost completely absorbed (90 to 95%) after a single oral dose. Due to the combined effects of first pass hepatic metabolism and high lipid solubility, only 10 to 20% of the administered dose reaches the systemic circulation. Relative bioavailability data from healthy male and female subjects suggest that a dose of 4.2 mg of SYNDROS provides comparable systemic exposure (C max and AUC) to a 5 mg dronabinol capsule, under fasted conditions [see Dosage and Administration ( 2.1 )] . The concentrations of both dronabinol and its major active metabolite (11-hydroxy-delta-9-THC) peak at approximately 0.5 to 4 hours after oral dosing with SYNDROS and decline over several days. The mean inter- and intra-subject variability in dronabinol pharmacokinetics (C max and AUC inf ) was approximately 66% and 47% and 67% and 14%, respectively, following administration of SYNDROS to healthy subjects.

-THC) peak at approximately 0.5 to 4 hours after oral dosing with SYNDROS and decline over several days. The mean inter- and intra-subject variability in dronabinol pharmacokinetics (C max and AUC inf ) was approximately 66% and 47% and 67% and 14%, respectively, following administration of SYNDROS to healthy subjects. Table 1: Summary of Single-Dose Pharmacokinetic Parameters of Dronabinol After Replicated Oral Administration of SYNDROS (4.2 mg to Healthy Subjects under Fasted Conditions) * Arithmetic mean ± standard deviation except T max for which the median [range] is reported Parameter* Dronabinol C max (ng/mL) 1.9 ± 1.3 T max (h) 1.0 [0.5 to 4.0] AUC (inf) (ng.h/mL) 3.8 ± 1.8 t ½ (h) 5.6 ± 2.7 Food Effect The effect of food on the pharmacokinetics of SYNDROS was studied by concomitant dosing of SYNDROS with a high-fat (59 grams of fat, approximately 50% of total caloric content of the meal), high calorie meal (approximately 950 calories). An appreciable food effect was observed: food resulted in approximately a 2.5-fold increase in total exposure (AUC inf ) and approximately a 5 hour delay in median T max . Food also decreased C max by approximately 20% [see Dosage and Administration ( 2.2 , 2.3 )] . Distribution Dronabinol has an apparent volume of distribution of approximately 10 L/kg, because of its lipid solubility. The plasma protein binding of dronabinol and its metabolites is approximately 97% [see Drug Interactions ( 7.3 )] . Elimination The pharmacokinetics of dronabinol can be described using a two compartment model with an initial (alpha) half-life of about 5 hours and a terminal (beta) half-life of 25 to 36 hours. Values for clearance average about 0.2 L/kg-hr; but are highly variable due to the complexity of cannabinoid distribution. Metabolism Dronabinol undergoes extensive first-pass hepatic metabolism, primarily by hydroxylation, yielding both active and inactive metabolites. The major metabolite (11-hydroxy-delta-9-THC) is pharmacologically active. Published in vitro data indicate that CYP2C9 and CYP3A4 are the primary enzymes in the metabolism of dronabinol. CYP2C9 appears to be the enzyme responsible for the formation of the primary active metabolite [see Clinical Pharmacology ( 12.5 )] . Excretion Dronabinol and its biotransformation products are excreted in both feces and urine. Biliary excretion is the major route of excretion with about half of a radio-labeled oral dose being recovered from the feces within 72 hours as contrasted with 10 to 15% recovered from urine. Less than 5% of an oral dose is recovered unchanged in the feces. Due to its re-distribution, dronabinol and its metabolites may be excreted for prolonged periods of time. Following single dose administration, dronabinol metabolites have been detected for more than 5 weeks in the urine and feces. In a study of dronabinol capsules involving AIDS patients, urinary cannabinoid/creatinine concentration ratios were studied bi-weekly over a six week period. The urinary cannabinoid/creatinine ratio was closely correlated with dose. No increase in the cannabinoid/creatinine ratio was observed after the first two weeks of treatment, indicating that steady-state cannabinoid levels had been reached. This conclusion is consistent with predictions based on the observed terminal half-life of dronabinol. Drug Interaction Studies Formal drug-drug interaction studies have not been conducted with dronabinol. The enzyme inhibition and induction potential of dronabinol and its active metabolite are not completely understood. Published data showed an increase in the elimination half-life of pentobarbital by 4 hours when concomitantly dosed with dronabinol [see Warnings and Precautions ( 5.1 )] .

The mean inter- and intra-subject variability in dronabinol pharmacokinetics (C max and AUC inf ) was approximately 66% and 47% and 67% and 14%, respectively, following administration of SYNDROS to healthy subjects. Table 1: Summary of Single-Dose Pharmacokinetic Parameters of Dronabinol After Replicated Oral Administration of SYNDROS (4.2 mg to Healthy Subjects under Fasted Conditions) * Arithmetic mean ± standard deviation except T max for which the median [range] is reported Parameter* Dronabinol C max (ng/mL) 1.9 ± 1.3 T max (h) 1.0 [0.5 to 4.0] AUC (inf) (ng.h/mL) 3.8 ± 1.8 t ½ (h) 5.6 ± 2.7 Food Effect The effect of food on the pharmacokinetics of SYNDROS was studied by concomitant dosing of SYNDROS with a high-fat (59 grams of fat, approximately 50% of total caloric content of the meal), high calorie meal (approximately 950 calories). An appreciable food effect was observed: food resulted in approximately a 2.5-fold increase in total exposure (AUC inf ) and approximately a 5 hour delay in median T max . Food also decreased C max by approximately 20% [see Dosage and Administration ( 2.2 , 2.3 )] . Distribution Dronabinol has an apparent volume of distribution of approximately 10 L/kg, because of its lipid solubility. The plasma protein binding of dronabinol and its metabolites is approximately 97% [see Drug Interactions ( 7.3 )] . Elimination The pharmacokinetics of dronabinol can be described using a two compartment model with an initial (alpha) half-life of about 5 hours and a terminal (beta) half-life of 25 to 36 hours. Values for clearance average about 0.2 L/kg-hr; but are highly variable due to the complexity of cannabinoid distribution. Metabolism Dronabinol undergoes extensive first-pass hepatic metabolism, primarily by hydroxylation, yielding both active and inactive metabolites. The major metabolite (11-hydroxy-delta-9-THC) is pharmacologically active. Published in vitro data indicate that CYP2C9 and CYP3A4 are the primary enzymes in the metabolism of dronabinol. CYP2C9 appears to be the enzyme responsible for the formation of the primary active metabolite [see Clinical Pharmacology ( 12.5 )] . Excretion Dronabinol and its biotransformation products are excreted in both feces and urine. Biliary excretion is the major route of excretion with about half of a radio-labeled oral dose being recovered from the feces within 72 hours as contrasted with 10 to 15% recovered from urine. Less than 5% of an oral dose is recovered unchanged in the feces. Due to its re-distribution, dronabinol and its metabolites may be excreted for prolonged periods of time. Following single dose administration, dronabinol metabolites have been detected for more than 5 weeks in the urine and feces.

recovered from urine. Less than 5% of an oral dose is recovered unchanged in the feces. Due to its re-distribution, dronabinol and its metabolites may be excreted for prolonged periods of time. Following single dose administration, dronabinol metabolites have been detected for more than 5 weeks in the urine and feces. In a study of dronabinol capsules involving AIDS patients, urinary cannabinoid/creatinine concentration ratios were studied bi-weekly over a six week period. The urinary cannabinoid/creatinine ratio was closely correlated with dose. No increase in the cannabinoid/creatinine ratio was observed after the first two weeks of treatment, indicating that steady-state cannabinoid levels had been reached. This conclusion is consistent with predictions based on the observed terminal half-life of dronabinol. Drug Interaction Studies Formal drug-drug interaction studies have not been conducted with dronabinol. The enzyme inhibition and induction potential of dronabinol and its active metabolite are not completely understood. Published data showed an increase in the elimination half-life of pentobarbital by 4 hours when concomitantly dosed with dronabinol [see Warnings and Precautions ( 5.1 )] .

12.5 Pharmacogenomics Published data indicate a 2- to 3-fold higher dronabinol exposure in individuals carrying genetic variants associated with diminished CYP2C9 function. 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility The recommended dose ranges for SYNDROS in AIDS and cancer patients are designed to achieve the same systemic exposure ranges as with the recommended dose ranges for dronabinol capsules. Therefore, the animal to human dose multiples for carcinogenicity studies, as shown below, are based on the MRHD (maximum recommended human dose) for dronabinol capsules in AIDS patients, instead of the MRHD for SYNDROS which is 15% lower. This approach for dose comparison between animals and humans is supported by the demonstrated difference in dronabinol bioavailability between SYNDROS and dronabinol capsules. The animal to human dose multiples for the fertility study in rats, as shown below, are based on the MRHD for dronabinol capsules in AIDS or cancer patients. In 2-year carcinogenicity studies, there was no evidence of carcinogenicity in rats at doses up to 50 mg/kg/day dronabinol (approximately 20 times the MRHD for dronabinol capsules in AIDS patients on a body surface area basis) or in mice at doses up to 500 mg/kg/day (approximately 100 times the MRHD for dronabinol capsules in AIDS patients on a body surface area basis). Dronabinol was not genotoxic in the Ames tests, the in vitro chromosomal aberration test in Chinese hamster ovary cells, and the in vivo mouse micronucleus test. However, dronabinol produced a weak positive response in a sister chromatid exchange test in Chinese hamster ovary cells. In a long-term study (77 days) in rats, oral administration of dronabinol at doses of 30 to 150 mg/m 2 , equivalent to 2 to 10 times the MRHD of 15 mg/m 2 /day (dronabinol capsules) in AIDS patients or 0.3 to 1.5 times the MRHD of 90 mg/m 2 /day (dronabinol capsules) in cancer patients, reduced ventral prostate, seminal vesicle and epididymal weights and caused a decrease in seminal fluid volume. Decreases in spermatogenesis, number of developing germ cells, and number of Leydig cells in the testis were also observed. However, sperm count, mating success and testosterone levels were not affected. The significance of these animal findings in humans is not known.

Step 5: Carefully turn the bottle upside down with the syringe tip firmly inserted into the adapter (See Figure G ). Step 6: Slowly pull back on the plunger until the measuring ring is at the line marking for the dose prescribed by your doctor. The measuring ring is the widest part of the plunger at the bottom of the tip of plunger. (See Figures H(a) and H(b) ). Figure H(a) shows a dose of 0.4 mL as an example. If you see air bubbles in the oral syringe, fully push in the plunger so that the oral solution flows back into the bottle. Then, withdraw your prescribed dose of oral solution. If your prescribed dose is more than 1 mL, you will need to draw up two or more doses. For example, if your dose is 1.2 mL, you will need to draw up a 1 mL dose followed by a 0.2 mL dose. Step 7: Leave the oral syringe in the adapter and turn the bottle to an upright position. Place the bottle onto a flat surface. Remove the oral syringe from the bottle adapter by gently pulling straight up on the oral syringe (See Figure I ).

2 DOSAGE AND ADMINISTRATION Anorexia Associated with Weight Loss in Adult Patients with AIDS ( 2.1 ): The recommended adult starting dosage is 2.5 mg orally twice daily, one hour before lunch and dinner. See the full prescribing information for dosage titration to manage adverse reactions and to achieve desired therapeutic effect. Nausea and Vomiting Associated with Chemotherapy in Adult Patients Who Failed Conventional Antiemetics ( 2.2 ): The recommended starting dosage is 5 mg/m 2 , administered 1 to 3 hours prior to the administration of chemotherapy, then every 2 to 4 hours after chemotherapy, for a total of 4 to 6 doses per day. Administer the first dose on an empty stomach at least 30 minutes prior to eating; subsequent doses can be taken without regard to meals. See the full prescribing information for dosage titration to manage adverse reactions and to achieve desired therapeutic effect. 2.1 Anorexia Associated with Weight Loss in Adult Patients with AIDS Starting Dosage The recommended adult starting dosage of dronabinol capsules is 2.5 mg orally twice daily, one hour before lunch and dinner. In elderly patients or patients unable to tolerate 2.5 mg twice daily, consider initiating dronabinol capsules at 2.5 mg once daily one hour before dinner or at bedtime to reduce the risk of central nervous system (CNS) symptoms [see Use in Specific Populations ( 8.5 )]. Dosing later in the day may reduce the frequency of CNS adverse reactions. CNS adverse reactions are dose-related [see Warnings and Precautions ( 5.1 )] ; therefore monitor patients and reduce the dosage as needed. If CNS adverse reactions of feeling high, dizziness, confusion, and somnolence occur, they usually resolve in 1 to 3 days and usually do not require dosage reduction. If CNS adverse reactions are severe or persistent, reduce the dosage to 2.5 mg in the evening or at bedtime. Dosage Titration If tolerated and further therapeutic effect is desired, the dosage may be increased gradually to 2.5 mg one hour before lunch and 5 mg one hour before dinner. Increase the dose of dronabinol capsules gradually in order to reduce the frequency of dose-related adverse reactions [see Warnings and Precautions ( 5.1 )]. Most patients respond to 2.5 mg twice daily, but the dose may be further increased to 5 mg one hour before lunch and 5 mg one hour before dinner, as tolerated to achieve a therapeutic effect. Maximum Dosage: 10 mg twice daily. 2.2 Nausea and Vomiting Associated with Cancer Chemotherapy in Adult Patients Who Failed Conventional Antiemetics Starting Dosage The recommended starting dosage of dronabinol capsules is 5 mg/m2, orally administered 1 to 3 hours prior to the administration of chemotherapy and then every 2 to 4 hours after chemotherapy, for a total of 4 to 6 doses per day. In elderly patients, consider initiating dronabinol capsules at 2.5 mg/m2 once daily 1 to 3 hours prior to chemotherapy to reduce the risk of CNS symptoms [see Use in Specific Populations ( 8.5 )]. Administer the first dose on an empty stomach at least 30 minutes before eating. Subsequent doses can be taken without regard to meals [see Clinical Pharmacology ( 12.3 )]. The timing of dosing in relation to meal times should be kept consistent for each chemotherapy cycle, once the dosage has been determined from the titration process.

st dose on an empty stomach at least 30 minutes before eating. Subsequent doses can be taken without regard to meals [see Clinical Pharmacology ( 12.3 )]. The timing of dosing in relation to meal times should be kept consistent for each chemotherapy cycle, once the dosage has been determined from the titration process. Dosage Titration The dosage can be titrated to clinical response during a chemotherapy cycle or subsequent cycles, based upon initial response, as tolerated to achieve a clinical effect, in increments of 2.5 mg/m2. The maximum dosage is 15 mg/m2 per dose for 4 to 6 doses per day. Adverse reactions are dose-related and psychiatric symptoms increase significantly at the maximum dosage [see Warnings and Precautions ( 5.1 )]. Monitor patients for adverse reactions and consider decreasing the dose to 2.5 mg once daily 1 to 3 hours prior to chemotherapy to reduce the risk of CNS adverse reactions.

5 WARNINGS AND PRECAUTIONS Neuropsychiatric Adverse Reactions: May cause psychiatric and cognitive effects and impair mental and/or physical abilities. Avoid use in patients with a psychiatric history. Monitor for symptoms and avoid concomitant use of drugs with similar effects. Inform patients not to operate motor vehicles or other dangerous machinery until they are reasonably certain that dronabinol capsules do not affect them adversely. ( 5.1 ) Hemodynamic Instability: Patients with cardiac disorders may experience hypotension, hypertension, syncope or tachycardia. Avoid concomitant use of drugs with similar effects and monitor for hemodynamic changes after initiating or increasing the dosage of dronabinol capsules. ( 5.2 ) Seizures and Seizure-like Activity: Weigh the potential risk versus benefits before prescribing dronabinol capsules to patients with a history of seizures, including those requiring anti-epileptic medication or with other factors that lower the seizure threshold. Monitor patients and discontinue if seizures occur. ( 5.3 ) Multiple Substance Abuse: Assess risk for abuse or misuse in patients with a history of substance abuse or dependence, prior to prescribing dronabinol capsules and monitor for the development of associated behaviors or conditions. ( 5.4 ) Paradoxical Nausea, Vomiting, or Abdominal Pain: Consider dose reduction or discontinuation, if worsening of symptoms while on treatment. ( 5.5 ) 5.1 Neuropsychiatric Adverse Reactions Psychiatric Adverse Reactions Dronabinol has been reported to exacerbate mania, depression, or schizophrenia. Significant CNS symptoms followed oral doses of 0.4 mg/kg (28 mg per 70 kg patient) of dronabinol capsules in antiemetic studies. Prior to initiating treatment with dronabinol capsules, screen patients for a history of these illnesses. Avoid use in patients with a psychiatric history or, if the drug cannot be avoided, monitor patients for new or worsening psychiatric symptoms during treatment. Also, avoid concomitant use with other drugs that are associated with similar psychiatric effects. Cognitive Adverse Reactions Use of dronabinol capsules has been associated with cognitive impairment and altered mental state. Reduce the dose of dronabinol capsules or discontinue use of dronabinol capsules if signs or symptoms of cognitive impairment develop. Elderly patients may be more sensitive to the neurological and psychoactive effects of dronabinol capsules [see Use in Specific Populations ( 8.4 , 8.5 )]. Hazardous Activities Dronabinol capsules can cause and may impair the mental and/or physical abilities required for the performance of hazardous tasks such as driving a motor vehicle or operating machinery. Concomitant use of other drugs that cause dizziness, confusion, sedation, or somnolence such as CNS depressants may increase this effect (e.g., barbiturates, benzodiazepines, ethanol, lithium, opioids, buspirone, scopolamine, antihistamines, tricyclic antidepressants, other anticholinergic agents, muscle relaxants). Inform patients not to operate motor vehicles or other dangerous machinery until they are reasonably certain that dronabinol capsules do not affect them adversely. 5.2 Hemodynamic Instability Patients may experience occasional hypotension, possible hypertension, syncope, or tachycardia while taking dronabinol capsules [see Clinical Pharmacology ( 12.2 )]. Patients with cardiac disorders may be at higher risk.

asonably certain that dronabinol capsules do not affect them adversely. 5.2 Hemodynamic Instability Patients may experience occasional hypotension, possible hypertension, syncope, or tachycardia while taking dronabinol capsules [see Clinical Pharmacology ( 12.2 )]. Patients with cardiac disorders may be at higher risk. Avoid concomitant use of other drugs that are also associated with similar cardiac effects (e.g., amphetamines, other sympathomimetic agents, atropine, amoxapine, scopolamine, antihistamines, other anticholinergic agents, amitriptyline, desipramine, other tricyclic antidepressants). Monitor patients for changes in blood pressure, heart rate, and syncope after initiating or increasing the dosage of dronabinol capsules. 5.3 Seizures Seizure and seizure-like activity have been reported in patients receiving dronabinol. Weigh this potential risk against the benefits before prescribing dronabinol capsules to patients with a history of seizures, including those receiving anti-epileptic medication or with other factors that can lower the seizure threshold. Monitor patients with a history of seizure disorders for worsened seizure control during dronabinol capsules therapy. If a seizure occurs, advise patients to discontinue dronabinol capsules and contact a healthcare provider immediately. 5.4 Multiple Substance Abuse Patients with a history of substance abuse or dependence, including marijuana or alcohol, may be more likely to abuse dronabinol capsules as well. Assess each patient’s risk for abuse or misuse prior to prescribing dronabinol capsules and monitor patients with a history of substance abuse during treatment with dronabinol capsules for the development of these behaviors or conditions. 5.5 Paradoxical Nausea, Vomiting, or Abdominal Pain Nausea, vomiting, or abdominal pain can occur during treatment with synthetic delta-9-tetrahydrocannabinol (delta-9-THC), the active ingredient in dronabinol capsules. In some cases, these adverse reactions were severe (e.g., dehydration, electrolyte abnormalities) and required dose reduction or drug discontinuation. Symptoms are similar to cannabinoid hyperemesis syndrome (CHS), which is described as cyclical events of abdominal pain, nausea, and vomiting in chronic, long-term users of delta-9-THC products. Because patients may not recognize these symptoms as abnormal, it is important to specifically ask patients or their caregivers about the development of worsening of nausea, vomiting, or abdominal pain while being treated with dronabinol capsules. Consider dose reduction or discontinuing dronabinol capsules if a patient develops worsening nausea, vomiting, or abdominal pain while on treatment.

The following serious adverse reactions are described below and elsewhere in the labeling. Neuropsychiatric Adverse Reactions [see Warnings and Precautions ( 5.1 )] Hemodynamic Instability [see Warnings and Precautions ( 5.2 )] Seizures [see Warnings and Precautions ( 5.3 )] Paradoxical Nausea, Vomiting, and Abdominal Pain [see Warnings and Precautions ( 5.5 )] Studies of AIDS-related weight loss included 157 patients receiving dronabinol capsules at a dose of 2.5 mg twice daily and 67 receiving placebo. Studies of nausea and vomiting related to cancer chemotherapy included 317 patients receiving dronabinol capsules and 68 receiving placebo. In the tables below is a summary of the adverse reactions in 474 patients exposed to dronabinol capsules in studies. Studies of different durations were combined by considering the first occurrence of events during the first 28 days. A cannabinoid dose-related “high” (easy laughing, elation and heightened awareness) has been reported by patients receiving dronabinol capsules in both the antiemetic (24%) and the lower dose appetite stimulant clinical trials (8%). The most frequently reported adverse experiences in patients with AIDS during placebo-controlled clinical trials involved the CNS and were reported by 33% of patients receiving dronabinol capsules. About 25% of patients reported a CNS adverse reaction during the first 2 weeks and about 4% reported such a reaction each week for the next 6 weeks thereafter. Common Adverse Reactions The following adverse reactions were reported in clinical trials at an incidence greater than 1%. System Organ Class Adverse Reactions General Asthenia Cardiovascular Palpitations, tachycardia, vasodilation/facial flush Gastrointestinal Abdominal pain*, nausea*, vomiting* Central Nervous System Dizziness*, euphoria*, paranoid reaction*, somnolence*, thinking abnormal*, amnesia, anxiety/nervousness, ataxia, confusion, depersonalization, hallucination * Actual incidence 3% to 10% Less Common Adverse Reactions The following adverse reactions were reported in clinical trials at an incidence less than or equal to 1%.

7 DRUG INTERACTIONS Inhibitors and inducers of CYP2C9 and CYP3A4: May alter dronabinol systemic exposure; monitor for potential dronabinol-related adverse reactions or loss of efficacy. ( 7.3 ) Highly protein-bound drugs: Potential for displacement of other drugs from plasma proteins; monitor for adverse reactions to concomitant highly protein-bound drugs and narrow therapeutic index drugs (e.g., warfarin, cyclosporine, amphotericin B) when initiating or increasing the dosage of dronabinol capsules. ( 7.4 ) 7.1 Additive CNS Effects Additive CNS effects (e.g., dizziness, confusion, sedation, somnolence) may occur when dronabinol capsules are taken concomitantly with drugs that have similar effects on the central nervous system such as CNS depressants [see Warnings and Precautions ( 5.1 )]. 7.2 Additive Cardiac Effects Additive cardiac effects (e.g., hypotension, hypertension, syncope, tachycardia) may occur when dronabinol capsules are taken concomitantly with drugs that have similar effects on the cardiovascular system [see Warnings and Precautions (5.2)]. 7.3 Effect of Other Drugs on Dronabinol Dronabinol is primarily metabolized by CYP2C9 and CYP3A4 enzymes based on published in vitro studies. Inhibitors of these enzymes may increase, while inducers may decrease, the systemic exposure of dronabinol and/or its active metabolite resulting in an increase in dronabinol-related adverse reactions or loss of efficacy of dronabinol capsules. Monitor for potentially increased dronabinol-related adverse reactions when dronabinol capsules are co-administered with inhibitors of CYP2C9 (e.g., amiodarone, fluconazole) and inhibitors of CYP3A4 enzymes (e.g., ketoconazole, itraconazole, clarithromycin, ritonavir, erythromycin, grapefruit juice). 7.4 Highly Protein-Bound Drugs Dronabinol is highly bound to plasma proteins, and therefore, might displace and increase the free fraction of other concomitantly administered protein-bound drugs. Although this displacement has not been confirmed in vivo, monitor patients for increased adverse reactions to narrow therapeutic index drugs that are highly protein-bound (e.g., warfarin, cyclosporine, amphotericin B) when initiating treatment or increasing the dosage of dronabinol capsules.

8 USE IN SPECIFIC POPULATIONS Pregnancy: May cause fetal harm. ( 8.1 ) Lactation: Advise HIV-infected women not to breastfeed due to the potential for HIV transmission. Weight should be monitored in breastfed infants of mothers with nausea and vomiting associated with cancer chemotherapy in whom breastfeeding is appropriate. ( 8.2 ) Geriatric Use: Elderly patients may be more sensitive to the neuropsychiatric and postural hypotensive effects. Consider a lower starting dose in elderly patients. ( 2.1 , 2.2 , 5.1 , 5.2 , 8.5 ) 8.1 Pregnancy Risk Summary Dronabinol capsules, a synthetic cannabinoid, may cause fetal harm. Avoid use of dronabinol capsules in pregnant women. Although there is little published data on the use of synthetic cannabinoids during pregnancy, use of cannabis (e.g., marijuana) during pregnancy has been associated with adverse fetal/neonatal outcomes (see Clinical Considerations). Cannabinoids have been found in the umbilical cord blood from pregnant women who smoke cannabis. In animal reproduction studies, no teratogenicity was reported in mice administered dronabinol (delta-9-THC) at up to 30 times the MRHD (maximum recommended human dose) and up to 5 times the MRHD for patients with AIDS and cancer, respectively. Similar findings were reported in pregnant rats administered dronabinol at up to 5 to 20 times the MRHD and 3 times the MRHD for patients with AIDS and cancer, respectively. Decreased maternal weight gain and number of viable pups and increased fetal mortality and early resorptions were observed in both species at doses which induced maternal toxicity. In rats, maternal administration of dronabinol from pregnancy (implantation) through weaning was associated with maternal toxicity including adverse clinical signs, increased stillbirths and mortality of offspring, and reduced pup bodyweight at 2 and 6 times the MRHD for patients with AIDS, and less than or equal to the MRHD for patients with cancer. No evidence of neurodevelopmental adverse effects was observed in the offspring at doses up to 6 times the MRHD for patients with AlDS, and up to the MRHD for patients with cancer (see Data) . The estimated background risk of major birth defects and miscarriage for the indicated populations are unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Fetal/Neonatal Adverse Reactions Published studies suggest that during pregnancy, the use of cannabis, which includes THC, whether for recreational or medicinal purposes, may increase the risk of adverse fetal/neonatal outcomes including fetal growth restriction, low birth weight, preterm birth, small-for-gestational age, admission to the neonatal intensive care unit, and stillbirth. Therefore, use of cannabis during pregnancy should be avoided. Data Human Data Delta-9-THC has been measured in the cord blood of some infants whose mothers reported prenatal use of cannabis, suggesting that dronabinol may cross the placenta to the fetus during pregnancy. The effects of delta-9-THC on the fetus are not known.

re, use of cannabis during pregnancy should be avoided. Data Human Data Delta-9-THC has been measured in the cord blood of some infants whose mothers reported prenatal use of cannabis, suggesting that dronabinol may cross the placenta to the fetus during pregnancy. The effects of delta-9-THC on the fetus are not known. Animal Data Reproduction studies with dronabinol have been performed in mice at 15 to 450 mg/m 2 , equivalent to 1 to 30 times the MRHD of 15 mg/m 2 /day in patients with AIDS or 0.2 to 5 times the MRHD of 90 mg/m 2 /day in patients with cancer, and in rats at 74 to 295 mg/m 2 (equivalent to 5 to 20 times the MRHD of 15 mg/m 2 /day in patients with AIDS or 0.8 to 3 times the MRHD of 90 mg/m 2 /day in patients with cancer). These studies have revealed no evidence of teratogenicity due to delta-9-THC. At these dronabinol dosages in mice and rats, delta-9-THC decreased maternal weight gain and number of viable pups and increased fetal mortality and early resorptions. Such effects were dose dependent and less apparent at lower doses that produced less maternal toxicity. Review of published literature indicates that the endocannabinoid system plays a role in neurodevelopmental processes such as neurogenesis, migration, and synaptogenesis. Exposure of pregnant rats to delta-9-THC (during and after organogenesis) may modulate these processes to result in abnormal patterns of neuronal connectivity and subsequent cognitive impairments in the offspring. Nonclinical toxicity studies in pregnant rats and newborn pups have shown prenatal exposure to delta-9-THC that resulted in impairment of motor function, alteration in synaptic activity, and interference in cortical projection of neuron development in the offspring. Prenatal exposure has shown effects on cognitive function such as learning, short-and long-term memory, attention, decreased ability to remember task, and ability to discriminate between novel and same objects. Overall, prenatal exposure to delta-9-THC has resulted in significant and long-term changes in brain development, cognition, and behavior in rat offspring. In a pre- and postnatal development study, female rats were administered dronabinol by oral gavage at doses of 0.5, 5, or 15 mg/kg /day (equivalent to 0.2, 2, and 6 times the MRHD for patients with AIDS and 0.03, 0.33, and 1.0 times the MRHD for patients with cancer, respectively, based on body surface area) from gestation day 6 (implantation) through lactation day 20 (weaning). Maternal toxicity including adverse clinical signs (i.e., decreased motor activity, low carriage, abnormal gait, hunched posture, vocalization to touch, ungroomed coat, mild dehydration, piloerection, and splayed hindlimbs), reduced body weight and body weight gain, and decreased food consumption were observed during the gestation period at 2 and 6 times the MRHD for patients with AIDS and 0.33 and 1.0 times the MRHD for patients with cancer, respectively. At the same doses, reduced pup bodyweight, increased stillbirths, and mortality of offspring were observed. No neurodevelopmental adverse effects (i.e., neurobehavioral function, sensory function, motor activity, learning and memory) were observed in pups at maternal doses up 15 mg/kg/day (6 times the MRHD in patients with AIDS or 1.0 times the MRI-ID in patients with cancer). 8.2 Lactation Risk Summary For mothers infected with the Human Immunodeficiency Virus (HIV), the Centers for Disease Control and Prevention recommends that HIV-infected mothers not breastfeed their infants to avoid risking postnatal transmission of HIV. Because of the potential for HIV transmission (in HIV-negative infants) and serious adverse reactions in a breastfed infant, instruct mothers not to breastfeed if they are receiving dronabinol capsules.

ion recommends that HIV-infected mothers not breastfeed their infants to avoid risking postnatal transmission of HIV. Because of the potential for HIV transmission (in HIV-negative infants) and serious adverse reactions in a breastfed infant, instruct mothers not to breastfeed if they are receiving dronabinol capsules. For mothers with nausea and vomiting associated with cancer chemotherapy, there are limited data on the presence of dronabinol in human milk, the effects on the breastfed infant, or the effects on milk production. The reported effects of inhaled cannabis transferred to the breastfeeding infant have been inconsistent and insufficient to establish causality. In rat offspring exposed to dronabinol in utero and during lactation, reduced bodyweight was observed during the preweaning (lactation) stage with maternal administration of dronabinol at 2 times and less than the MRHD for patients with AIDS and cancer, respectively. Breastfeeding infants should have their weight monitored. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for dronabinol and any potential adverse effects on the breastfed infant from dronabinol or from the underlying maternal condition. 8.4 Pediatric Use The safety and effectiveness of dronabinol capsules have not been established in pediatric patients. Pediatric patients may be more sensitive to neurological and psychoactive effects of dronabinol capsules [see Warnings and Precautions ( 5.1 )]. 8.5 Geriatric Use Clinical studies of dronabinol capsules in AIDS and cancer patients did not include the sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Elderly patients may be more sensitive to the neuropsychiatric and postural hypotensive effects of dronabinol capsules [see Warnings and Precautions ( 5.1 , 5.2 )]. Elderly patients with dementia are at increased risk for falls as a result of their underlying disease state, which may be exacerbated by the CNS effects of somnolence and dizziness associated with dronabinol capsules [see Warnings and Precautions ( 5.1 )]. These patients should be monitored closely and placed on fall precautions prior to initiating dronabinol capsule therapy. In antiemetic studies, no difference in efficacy was apparent in patients greater than 55 years of age compared to younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of falls, decreased hepatic, renal, or cardiac function, increased sensitivity to psychoactive effects, and of concomitant disease or other drug therapy [see Dosage and Administration ( 2.1 , 2.2 )]. 8.6 Effect of CYP2C9 Polymorphism Published data suggest that systemic clearance of dronabinol may be reduced and concentrations may be increased in the presence of CYP2C9 genetic polymorphism. Monitoring for potentially increased adverse reactions is recommended in patients known to carry genetic variants associated with diminished CYP2C9 function [see Clinical Pharmacology ( 12.5 )].

The reported effects of inhaled cannabis transferred to the breastfeeding infant have been inconsistent and insufficient to establish causality. In rat offspring exposed to dronabinol in utero and during lactation, reduced bodyweight was observed during the preweaning (lactation) stage with maternal administration of dronabinol at 2 times and less than the MRHD for patients with AIDS and cancer, respectively. Breastfeeding infants should have their weight monitored. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for dronabinol and any potential adverse effects on the breastfed infant from dronabinol or from the underlying maternal condition.

8.5 Geriatric Use Clinical studies of dronabinol capsules in AIDS and cancer patients did not include the sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Elderly patients may be more sensitive to the neuropsychiatric and postural hypotensive effects of dronabinol capsules [see Warnings and Precautions ( 5.1 , 5.2 )]. Elderly patients with dementia are at increased risk for falls as a result of their underlying disease state, which may be exacerbated by the CNS effects of somnolence and dizziness associated with dronabinol capsules [see Warnings and Precautions ( 5.1 )]. These patients should be monitored closely and placed on fall precautions prior to initiating dronabinol capsule therapy. In antiemetic studies, no difference in efficacy was apparent in patients greater than 55 years of age compared to younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of falls, decreased hepatic, renal, or cardiac function, increased sensitivity to psychoactive effects, and of concomitant disease or other drug therapy [see Dosage and Administration ( 2.1 , 2.2 )].

9 DRUG ABUSE AND DEPENDENCE 9.1 Controlled Substance Dronabinol capsules, a Schedule III controlled substance. 9.2 Abuse Abuse is the intentional, non-therapeutic use of a drug, even once, for its desirable psychological or physiological effects. Misuse is the intentional use, for therapeutic purposes, of a drug by an individual in a way other than prescribed by a healthcare provider or for whom it was not prescribed. Drug addiction is a cluster of behavioral, cognitive, and physiological phenomena that may include a strong desire to take the drug, difficulties in controlling drug use (e.g., continuing drug use despite harmful consequences, giving a higher priority to drug use than other activities and obligations), and possible tolerance or physical dependence. Dronabinol capsules contains dronabinol, the main psychoactive component in marijuana. Ingestion of high doses of dronabinol increases the risk of psychiatric adverse reactions if abused or misused, while continued administration can lead to addiction. Psychiatric adverse reactions may include psychosis, hallucinations, depersonalization, mood alteration, and paranoia. In an open-label study in patients with AIDS who received dronabinol capsules for up to five months, no abuse, or systematic change in personality or social functioning were observed despite the inclusion of a substantial number of patients with a past history of drug abuse. Patients should be instructed to keep dronabinol capsules in a secure place out of reach of others for whom the medication has not been prescribed. 9.3 Dependence Physical dependence is a state that develops as a result of physiological adaptation in response to repeated drug use, manifested by withdrawal signs and symptoms after abrupt discontinuation or a significant dose reduction of a drug. The appearance of a withdrawal syndrome when administration of the drug is terminated is the only actual evidence of physical dependence. Physical dependence can develop during chronic therapy with dronabinol capsules, and develops after chronic abuse of marijuana. A withdrawal syndrome was reported after the abrupt discontinuation of dronabinol in subjects receiving dosages of 210 mg per day for 12 to 16 consecutive days. Within 12 hours after discontinuation, subjects manifested symptoms such as irritability, insomnia, and restlessness. By approximately 24 hours post-dronabinol discontinuation, withdrawal symptoms intensified to include “hot flashes,” sweating, rhinorrhea, loose stools, hiccoughs, and anorexia. These withdrawal symptoms gradually dissipated over the next 48 hours. Electroencephalographic changes consistent with the effects of drug withdrawal (hyperexcitation) were recorded in patients after abrupt dechallenge. Patients also complained of disturbed sleep for several weeks after discontinuing therapy with high dosages of dronabinol.

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Dronabinol is an orally active cannabinoid which has complex effects on the CNS, including central sympathomimetic activity. Cannabinoid receptors have been discovered in neural tissues. These receptors may play a role in mediating the effects of dronabinol. 12.2 Pharmacodynamics Effects on the Cardiovascular System Dronabinol-induced sympathomimetic activity may result in tachycardia and/or conjunctival injection. Its effects on blood pressure are inconsistent, but subjects have experienced orthostatic hypotension and/or syncope upon abrupt standing [see Warnings and Precautions ( 5.2 )]. Effects on the Central Nervous System Dronabinol also demonstrates reversible effects on appetite, mood, cognition, memory, and perception. These phenomena appear to be dose-related, increasing in frequency with higher dosages, and subject to great inter-patient variability. After oral administration, dronabinol has an onset of action of approximately 0.5 to 1 hours and peak effect at 2 to 4 hours. Duration of action for psychoactive effects is 4 to 6 hours, but the appetite stimulant effect of dronabinol may continue for 24 hours or longer after administration. Tachyphylaxis and tolerance develop to some of the pharmacologic effects of dronabinol with chronic use, suggesting an indirect effect on sympathetic neurons. In a study of the pharmacodynamics of chronic dronabinol exposure, healthy male subjects (N = 12) received 210 mg per day of dronabinol capsules, administered orally in divided doses, for 16 days. An initial tachycardia induced by dronabinol was replaced successively by normal sinus rhythm and then bradycardia. A decrease in supine blood pressure, made worse by standing, was also observed initially. These subjects developed tolerance to the cardiovascular and subjective adverse CNS effects of dronabinol within 12 days of treatment initiation. Tachyphylaxis and tolerance do not appear to develop to the appetite stimulant effect of dronabinol capsules. In clinical studies involving AIDS patients, the appetite stimulant effect of dronabinol capsules was sustained for up to five months at dosages ranging from 2.5 mg to 20 mg per day. 12.3 Pharmacokinetics Absorption Dronabinol (delta-9-THC) is almost completely absorbed (90 to 95%) after single oral doses. Due to the combined effects of first pass hepatic metabolism and high lipid solubility, only 10 to 20% of the administered dose reaches the systemic circulation. Concentrations of both parent drug and its major active metabolite (11-hydroxy-delta-9-THC) peak at approximately 0.5 to 4 hours after oral dosing and decline over several days. The pharmacokinetics of dronabinol after single doses (2.5, 5, and 10 mg) and multiple doses (2.5, 5, and 10 mg given twice a day) have been studied in healthy subjects. Summary of Multiple-Dose Pharmacokinetic Parameters of Dronabinol in Healthy Subjects (n=34; 20-45 years) under Fasted Conditions Mean (SD) PK Parameter Values Twice Daily Dose C max ng/mL Median T max (range), hr AUC (0-12) ng•hr/mL 2.5 mg 1.32 (0.62) 1.00 (0.50-4.00) 2.88 (1.57) 5 mg 2.96 (1.81) 2.50 (0.50-4.00) 6.16 (1.85) 10 mg 7.88 (4.54) 1.50 (0.50-3.50) 15.2 (5.52) C max : maximum observed plasma concentration; T max : time to maximum observed plasma concentration; AUC (0-12) : area under the plasma concentration-time curve from 0 to 12 hours.

A slight increase in dose proportionality on mean C max and AUC (0-12) of dronabinol was observed with increasing dose over the dose range studied. Effect of Food: In a published study, the effect of food on the pharmacokinetics of dronabinol was studied by concomitant dosing of dronabinol capsules with a high-fat (59 grams of fat, approximately 50% of total caloric content of the meal), high calorie meal (approximately 950 calories). An appreciable food effect was observed, resulting in a 4-hour delay in mean T max and 2.9-fold increase in total exposure (AUC inf ), but C max was not significantly changed [see Dosage and Administration ( 2.2 )]. Distribution Dronabinol has an apparent volume of distribution of approximately 10 L/kg, because of its lipid solubility. The plasma protein binding of dronabinol and its metabolites is approximately 97% [see Drug Interactions ( 7.4 )]. Elimination The pharmacokinetics of dronabinol can be described using a two compartment model with an initial (alpha) half-life of about 4 hours and a terminal (beta) half-life of 25 to 36 hours. Values for clearance average about 0.2 L/kg-hr, but are highly variable due to the complexity of cannabinoid distribution. Metabolism Dronabinol undergoes extensive first-pass hepatic metabolism, primarily by hydroxylation, yielding both active and inactive metabolites. Dronabinol and its principal active metabolite, 11-hydroxy-delta-9-THC, are present in approximately equal concentrations in plasma. Published in vitro data indicates that CYP2C9 and CYP3A4 are the primary enzymes in the metabolism of dronabinol. CYP2C9 appears to be the enzyme responsible for the formation of the primary active metabolite [see Clinical Pharmacology ( 12.5 )]. Excretion Dronabinol and its biotransformation products are excreted in both feces and urine. Biliary excretion is the major route of elimination with about half of a radio-labeled oral dose being recovered from the feces within 72 hours as contrasted with 10 to 15% recovered from urine. Less than 5% of an oral dose is recovered unchanged in the feces. Due to its re-distribution, dronabinol and its metabolites may be excreted at low levels for prolonged periods of time. Following single dose administration, low levels of dronabinol metabolites have been detected for more than 5 weeks in the urine and feces. In a study of dronabinol capsules involving AIDS patients, urinary cannabinoid/creatinine concentration ratios were studied bi-weekly over a six week period. The urinary cannabinoid/creatinine ratio was closely correlated with dose. No increase in the cannabinoid/creatinine ratio was observed after the first two weeks of treatment, indicating that steady-state cannabinoid levels had been reached. This conclusion is consistent with predictions based on the observed terminal half-life of dronabinol. Drug Interaction Studies Formal drug-drug interaction studies have not been conducted with dronabinol. The enzyme inhibition and induction potential of dronabinol and its active metabolite are not completely understood. Published data showed an increase in the elimination half-life of pentobarbital by 4 hours when concomitantly dosed with dronabinol [see Warnings and Precautions ( 5.1 )]. 12.5 Pharmacogenomics Published data indicate a potentially 2-to 3-fold higher dronabinol exposure in individuals carrying genetic variants associated with diminished CYP2C9 function.

13 NONCLINICAL TOXICOLOGY 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility In 2-year carcinogenicity studies, there was no evidence of carcinogenicity in rats at doses up to 50 mg/kg/day dronabinol (approximately 20 times the MRHD in AIDS patients on a body surface area basis) or in mice at doses up to 500 mg/kg/day (approximately 100 times the MRHD in AIDS patients on a body surface area basis). Dronabinol was not genotoxic in the Ames tests, the in vitro chromosomal aberration test in Chinese hamster ovary cells, and the in vivo mouse micronucleus test. However, dronabinol produced a weak positive response in a sister chromatid exchange test in Chinese hamster ovary cells. In a long-term study (77 days) in rats, oral administration of dronabinol at doses of 30 to 150 mg/m2, equivalent to 2 to 10 times the MRHD of 15 mg/m2/day in AIDS patients or 0.3 to 1.5 times the MRHD of 90 mg/m2/day in cancer patients, reduced ventral prostate, seminal vesicle and epididymal weights and caused a decrease in seminal fluid volume. Decreases in spermatogenesis, number of developing germ cells, and number of Leydig cells in the testis were also observed. However, sperm count, mating success, and testosterone levels were not affected. The significance of these animal findings in humans is not known.

14 CLINICAL STUDIES The effectiveness of dronabinol capsules has been established based on studies for the treatment of anorexia associated with weight loss in patients with AIDS and nausea and vomiting associated with cancer chemotherapy in patients who have failed to respond adequately to conventional antiemetic treatments. 14.1 Appetite Stimulation The appetite stimulant effect of dronabinol capsules in the treatment of AIDS-related anorexia associated with weight loss was studied in a randomized, double-blind, placebo-controlled study involving 139 patients. The initial dosage of dronabinol capsules in all patients was 5 mg/day, administered in doses of 2.5 mg one hour before lunch and one hour before dinner. In pilot studies, early morning administration of dronabinol capsules appeared to have been associated with an increased frequency of adverse experiences, as compared to dosing later in the day. The effect of dronabinol capsules on appetite, weight, mood, and nausea was measured at scheduled intervals during the six-week treatment period. Side effects (feeling high, dizziness, confusion, somnolence) occurred in 13 of 72 patients (18%) at this dosage level and the dosage was reduced to 2.5 mg/day, administered as a single dose at supper or bedtime. Of the 112 patients that completed at least 2 visits in the randomized, double-blind, placebo-controlled study, 99 patients had appetite data at 4-weeks (50 received dronabinol capsules and 49 received placebo) and 91 patients had appetite data at 6-weeks (46 received dronabinol capsules and 45 received placebo). A statistically significant difference between dronabinol capsules and placebo was seen in appetite as measured by the visual analog scale at weeks 4 and 6 (see figure). Trends toward improved body weight and mood, and decreases in nausea were also seen. After completing the 6-week study, patients were allowed to continue treatment with dronabinol capsules in an open-label study, in which there was a sustained improvement in appetite. dronabinol-fig.jpg

Dronabinol capsules are a cannabinoid indicated in adults for the treatment of: Anorexia associated with weight loss in patients with AIDS. (1) Nausea and vomiting associated with cancer chemotherapy in patients who have failed to respond adequately to conventional antiemetic treatments. (1)

dosage_and_administrationopenfda· Dosage and Administration· item 197635

2 DOSAGE AND ADMINISTRATION Anorexia Associated with Weight Loss in Adult Patients with AIDS (2.1) : The recommended adult starting dosage is 2.5 mg orally twice daily, one hour before lunch and dinner. See the full prescribing information for dosage titration to manage adverse reactions and to achieve desired therapeutic effect. Nausea and Vomiting Associated with Chemotherapy in Adult Patients Who Failed Conventional Antiemetics (2.2) : The recommended starting dosage is 5 mg/m 2 , administered 1 to 3 hours prior to the administration of chemotherapy, then every 2 to 4 hours after chemotherapy, for a total of 4 to 6 doses per day. Administer the first dose on an empty stomach at least 30 minutes prior to eating; subsequent doses can be taken without regard to meals. See the full prescribing information for dosage titration to manage adverse reactions and to achieve desired therapeutic effect. 2.1 Anorexia Associated with Weight Loss in Adult Patients with AIDS Starting Dosage The recommended adult starting dosage of dronabinol capsules is 2.5 mg orally twice daily, one hour before lunch and dinner. In elderly patients or patients unable to tolerate 2.5 mg twice daily, consider initiating dronabinol capsules at 2.5 mg once daily one hour before dinner or at bedtime to reduce the risk of central nervous system (CNS) symptoms [see Use in Specific Populations (8.5) ]. Dosing later in the day may reduce the frequency of CNS adverse reactions. CNS adverse reactions are dose-related [see Warnings and Precautions (5.1) ]; therefore, monitor patients and reduce the dosage as needed. If CNS adverse reactions of feeling high, dizziness, confusion, and somnolence occur, they usually resolve in 1 to 3 days and usually do not require dosage reduction. If CNS adverse reactions are severe or persistent, reduce the dosage to 2.5 mg in the evening or at bedtime. Dosage Titration If tolerated and further therapeutic effect is desired, the dosage may be increased gradually to 2.5 mg one hour before lunch and 5 mg one hour before dinner. Increase the dose of dronabinol capsules gradually in order to reduce the frequency of dose-related adverse reactions [see Warnings and Precautions (5.1) ]. Most patients respond to 2.5 mg twice daily, but the dose may be further increased to 5 mg one hour before lunch and 5 mg one hour before dinner, as tolerated to achieve a therapeutic effect. Maximum Dosage: 10 mg twice daily. 2.2 Nausea and Vomiting Associated with Cancer Chemotherapy in Adult Patients Who Failed Conventional Antiemetics Starting Dosage The recommended starting dosage of dronabinol capsules is 5 mg/m 2 , orally administered 1 to 3 hours prior to the administration of chemotherapy and then every 2 to 4 hours after chemotherapy, for a total of 4 to 6 doses per day. In elderly patients, consider initiating dronabinol capsules at 2.5 mg/m 2 once daily 1 to 3 hours prior to chemotherapy to reduce the risk of CNS symptoms [see Use in Specific Populations (8.5) ]. Administer the first dose on an empty stomach at least 30 minutes before eating. Subsequent doses can be taken without regard to meals [see Clinical Pharmacology (12.3) ]. The timing of dosing in relation to meal times should be kept consistent for each chemotherapy cycle, once the dosage has been determined from the titration process.

rst dose on an empty stomach at least 30 minutes before eating. Subsequent doses can be taken without regard to meals [see Clinical Pharmacology (12.3) ]. The timing of dosing in relation to meal times should be kept consistent for each chemotherapy cycle, once the dosage has been determined from the titration process. Dosage Titration The dosage can be titrated to clinical response during a chemotherapy cycle or subsequent cycles, based upon initial response, as tolerated to achieve a clinical effect, in increments of 2.5 mg/m 2 . The maximum dosage is 15 mg/m 2 per dose for 4 to 6 doses per day. Adverse reactions are dose-related and psychiatric symptoms increase significantly at the maximum dosage [see Warnings and Precautions (5.1) ]. Monitor patients for adverse reactions and consider decreasing the dose to 2.5 mg once daily 1 to 3 hours prior to chemotherapy to reduce the risk of CNS adverse reactions.

5 WARNINGS AND PRECAUTIONS Neuropsychiatric Adverse Reactions : May cause psychiatric and cognitive effects and impair mental and/or physical abilities. Avoid use in patients with a psychiatric history. Monitor for symptoms and avoid concomitant use of drugs with similar effects. Inform patients not to operate motor vehicles or other dangerous machinery until they are reasonably certain that dronabinol capsules do not affect them adversely. (5.1) Hemodynamic Instability : Patients with cardiac disorders may experience hypotension, hypertension, syncope or tachycardia. Avoid concomitant use of drugs with similar effects and monitor for hemodynamic changes after initiating or increasing the dosage of dronabinol capsules. (5.2) Seizures and Seizure-like Activity : Weigh the potential risk versus benefits before prescribing dronabinol capsules to patients with a history of seizures, including those requiring anti-epileptic medication or with other factors that lower the seizure threshold. Monitor patients and discontinue if seizures occur. (5.3) Multiple Substance Abuse : Assess risk for abuse or misuse in patients with a history of substance abuse or dependence, prior to prescribing dronabinol capsules and monitor for the development of associated behaviors or conditions. (5.4) Paradoxical Nausea, Vomiting, or Abdominal Pain : Consider dose reduction or discontinuation, if worsening of symptoms while on treatment. (5.5) 5.1 Neuropsychiatric Adverse Reactions Psychiatric Adverse Reactions Dronabinol has been reported to exacerbate mania, depression, or schizophrenia. Significant CNS symptoms followed oral doses of 0.4 mg/kg (28 mg per 70 kg patient) of dronabinol capsules in antiemetic studies. Prior to initiating treatment with dronabinol capsules, screen patients for a history of these illnesses. Avoid use in patients with a psychiatric history or, if the drug cannot be avoided, monitor patients for new or worsening psychiatric symptoms during treatment. Also, avoid concomitant use with other drugs that are associated with similar psychiatric effects. Cognitive Adverse Reactions Use of dronabinol capsules has been associated with cognitive impairment and altered mental state. Reduce the dose of dronabinol capsules or discontinue use of dronabinol capsules if signs or symptoms of cognitive impairment develop. Elderly patients may be more sensitive to the neurological and psychoactive effects of dronabinol capsules [see Use in Specific Populations (8.4 , 8.5) ]. Hazardous Activities Dronabinol capsules can cause and may impair the mental and/or physical abilities required for the performance of hazardous tasks such as driving a motor vehicle or operating machinery. Concomitant use of other drugs that cause dizziness, confusion, sedation, or somnolence such as CNS depressants may increase this effect (e.g., barbiturates, benzodiazepines, ethanol, lithium, opioids, buspirone, scopolamine, antihistamines, tricyclic antidepressants, other anticholinergic agents, muscle relaxants). Inform patients not to operate motor vehicles or other dangerous machinery until they are reasonably certain that dronabinol capsules do not affect them adversely. 5.2 Hemodynamic Instability Patients may experience occasional hypotension, possible hypertension, syncope, or tachycardia while taking dronabinol capsules [see Clinical Pharmacology (12.2) ]. Patients with cardiac disorders may be at higher risk.

warnings_and_cautionsopenfda· Warnings and Cautions· item 197635

easonably certain that dronabinol capsules do not affect them adversely. 5.2 Hemodynamic Instability Patients may experience occasional hypotension, possible hypertension, syncope, or tachycardia while taking dronabinol capsules [see Clinical Pharmacology (12.2) ]. Patients with cardiac disorders may be at higher risk. Avoid concomitant use of other drugs that are also associated with similar cardiac effects (e.g., amphetamines, other sympathomimetic agents, atropine, amoxapine, scopolamine, antihistamines, other anticholinergic agents, amitriptyline, desipramine, other tricyclic antidepressants). Monitor patients for changes in blood pressure, heart rate, and syncope after initiating or increasing the dosage of dronabinol capsules. 5.3 Seizures Seizure and seizure-like activity have been reported in patients receiving dronabinol. Weigh this potential risk against the benefits before prescribing dronabinol capsules to patients with a history of seizures, including those receiving anti-epileptic medication or with other factors that can lower the seizure threshold. Monitor patients with a history of seizure disorders for worsened seizure control during dronabinol capsules therapy. If a seizure occurs, advise patients to discontinue dronabinol capsules and contact a healthcare provider immediately. 5.4 Multiple Substance Abuse Patients with a history of substance abuse or dependence, including marijuana or alcohol, may be more likely to abuse dronabinol capsules as well. Assess each patient's risk for abuse or misuse prior to prescribing dronabinol capsules and monitor patients with a history of substance abuse during treatment with dronabinol capsules for the development of these behaviors or conditions. 5.5 Paradoxical Nausea, Vomiting, or Abdominal Pain Nausea, vomiting, or abdominal pain can occur during treatment with synthetic delta-9‑tetrahydrocannabinol (delta-9-THC), the active ingredient in dronabinol capsules. In some cases, these adverse reactions were severe (e.g., dehydration, electrolyte abnormalities) and required dose reduction or drug discontinuation. Symptoms are similar to cannabinoid hyperemesis syndrome (CHS), which is described as cyclical events of abdominal pain, nausea, and vomiting in chronic, long-term users of delta-9-THC products. Because patients may not recognize these symptoms as abnormal, it is important to specifically ask patients or their caregivers about the development of worsening of nausea, vomiting, or abdominal pain while being treated with dronabinol capsules. Consider dose reduction or discontinuing dronabinol capsules if a patient develops worsening nausea, vomiting, or abdominal pain while on treatment.

6 ADVERSE REACTIONS Most common adverse reactions (≥3%) are: abdominal pain, dizziness, euphoria, nausea, paranoid reaction, somnolence, thinking abnormal, and vomiting. (6.1) To report SUSPECTED ADVERSE REACTIONS, contact Rhodes Pharmaceuticals at 1-888-827-0616, or FDA at 1-800-FDA-1088, or www.fda.gov/medwatch 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The following serious adverse reactions are described below and elsewhere in the labeling. Neuropsychiatric Adverse Reactions [see Warnings and Precautions (5.1) ] Hemodynamic Instability [see Warnings and Precautions (5.2) ] Seizures [see Warnings and Precautions (5.3) ] Paradoxical Nausea, Vomiting, and Abdominal Pain [see Warnings and Precautions (5.5) ] Studies of AIDS-related weight loss included 157 patients receiving dronabinol capsules at a dose of 2.5 mg twice daily and 67 receiving placebo. Studies of nausea and vomiting related to cancer chemotherapy included 317 patients receiving dronabinol capsules and 68 receiving placebo. In the tables below is a summary of the adverse reactions in 474 patients exposed to dronabinol capsules in studies. Studies of different durations were combined by considering the first occurrence of events during the first 28 days. A cannabinoid dose-related "high" (easy laughing, elation, and heightened awareness) has been reported by patients receiving dronabinol capsules in both the antiemetic (24%) and the lower dose appetite stimulant clinical trials (8%). The most frequently reported adverse experiences in patients with AIDS during placebo-controlled clinical trials involved the CNS and were reported by 33% of patients receiving dronabinol capsules. About 25% of patients reported a CNS adverse reaction during the first 2 weeks and about 4% reported such a reaction each week for the next 6 weeks thereafter. Common Adverse Reactions The following adverse reactions were reported in clinical trials at an incidence greater than 1%. System Organ Class Adverse Reactions General Asthenia Cardiovascular Palpitations, tachycardia, vasodilation/facial flush Gastrointestinal Abdominal pain Actual incidence 3% to 10% , nausea , vomiting Central Nervous System Dizziness , euphoria , paranoid reaction , somnolence , thinking abnormal , amnesia, anxiety/nervousness, ataxia, confusion, depersonalization, hallucination Less Common Adverse Reactions The following adverse reactions were reported in clinical trials at an incidence less than or equal to 1%.

7 DRUG INTERACTIONS Inhibitors and inducers of CYP2C9 and CYP3A4 : May alter dronabinol systemic exposure; monitor for potential dronabinol-related adverse reactions or loss of efficacy. (7.3) Highly protein-bound drugs: Potential for displacement of other drugs from plasma proteins; monitor for adverse reactions to concomitant highly protein-bound drugs and narrow therapeutic index drugs (e.g., warfarin, cyclosporine, amphotericin B) when initiating or increasing the dosage of dronabinol capsules. (7.4) 7.1 Additive CNS Effects Additive CNS effects (e.g., dizziness, confusion, sedation, somnolence) may occur when dronabinol capsules are taken concomitantly with drugs that have similar effects on the central nervous system such as CNS depressants [see Warnings and Precautions (5.1) ]. 7.2 Additive Cardiac Effects Additive cardiac effects (e.g., hypotension, hypertension, syncope, tachycardia) may occur when dronabinol capsules are taken concomitantly with drugs that have similar effects on the cardiovascular system [see Warnings and Precautions (5.2) ]. 7.3 Effect of Other Drugs on Dronabinol Dronabinol is primarily metabolized by CYP2C9 and CYP3A4 enzymes based on published in vitro studies. Inhibitors of these enzymes may increase, while inducers may decrease, the systemic exposure of dronabinol and/or its active metabolite resulting in an increase in dronabinol-related adverse reactions or loss of efficacy of dronabinol capsules. Monitor for potentially increased dronabinol-related adverse reactions when dronabinol capsules are co-administered with inhibitors of CYP2C9 (e.g., amiodarone, fluconazole) and inhibitors of CYP3A4 enzymes (e.g., ketoconazole, itraconazole, clarithromycin, ritonavir, erythromycin, grapefruit juice). 7.4 Highly Protein-Bound Drugs Dronabinol is highly bound to plasma proteins, and therefore, might displace and increase the free fraction of other concomitantly administered protein-bound drugs. Although this displacement has not been confirmed in vivo , monitor patients for increased adverse reactions to narrow therapeutic index drugs that are highly protein-bound (e.g., warfarin, cyclosporine, amphotericin B) when initiating treatment or increasing the dosage of dronabinol capsules.

8 USE IN SPECIFIC POPULATIONS Pregnancy : May cause fetal harm. (8.1) Lactation : Advise HIV-infected women not to breastfeed due to the potential for HIV transmission. Weight should be monitored in breastfed infants of mothers with nausea and vomiting associated with cancer chemotherapy in whom breastfeeding is appropriate. (8.2) Geriatric Use: Elderly patients may be more sensitive to the neuropsychiatric and postural hypotensive effects. Consider a lower starting dose in elderly patients. (2.1 , 2.2 , 5.1 , 5.2 , 8.5) 8.1 Pregnancy Risk Summary Dronabinol capsules, a synthetic cannabinoid, may cause fetal harm. Avoid use of dronabinol capsules in pregnant women. Although there is little published data on the use of synthetic cannabinoids during pregnancy, use of cannabis (e.g., marijuana) during pregnancy has been associated with adverse fetal/neonatal outcomes [see Clinical Considerations]. Cannabinoids have been found in the umbilical cord blood from pregnant women who smoke cannabis. In animal reproduction studies, no teratogenicity was reported in mice administered dronabinol (delta-9-THC) at up to 30 times the MRHD (maximum recommended human dose) and up to 5 times the MRHD for patients with AIDS and cancer, respectively. Similar findings were reported in pregnant rats administered dronabinol at up to 5 to 20 times the MRHD and 3 times the MRHD for patients with AIDS and cancer, respectively. Decreased maternal weight gain and number of viable pups and increased fetal mortality and early resorptions were observed in both species at doses which induced maternal toxicity. In rats, maternal administration of dronabinol from pregnancy (implantation) through weaning was associated with maternal toxicity including adverse clinical signs, increased stillbirths and mortality of offspring, and reduced pup bodyweight at 2 and 6 times the MRHD for patients with AIDS, and less than or equal to the MRHD for patients with cancer. No evidence of neurodevelopmental adverse effects was observed in the offspring at doses up to 6 times the MRHD for patients with AIDS, and up to the MRHD for patients with cancer [see Data]. The estimated background risk of major birth defects and miscarriage for the indicated populations are unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Fetal/Neonatal Adverse Reactions Published studies suggest that during pregnancy, the use of cannabis, which includes THC, whether for recreational or medicinal purposes, may increase the risk of adverse fetal/neonatal outcomes including fetal growth restriction, low birth weight, preterm birth, small-for-gestational age, admission to the neonatal intensive care unit, and stillbirth. Therefore, use of cannabis during pregnancy should be avoided. Data Human Data Delta-9-THC has been measured in the cord blood of some infants whose mothers reported prenatal use of cannabis, suggesting that dronabinol may cross the placenta to the fetus during pregnancy. The effects of delta-9-THC on the fetus are not known.

re, use of cannabis during pregnancy should be avoided. Data Human Data Delta-9-THC has been measured in the cord blood of some infants whose mothers reported prenatal use of cannabis, suggesting that dronabinol may cross the placenta to the fetus during pregnancy. The effects of delta-9-THC on the fetus are not known. Animal Data Reproduction studies with dronabinol have been performed in mice at 15 to 450 mg/m 2 , equivalent to 1 to 30 times the MRHD of 15 mg/m 2 /day in patients with AIDS or 0.2 to 5 times the MRHD of 90 mg/m 2 /day in patients with cancer, and in rats at 74 to 295 mg/m 2 (equivalent to 5 to 20 times the MRHD of 15 mg/m 2 /day in patients with AIDS or 0.8 to 3 times the MRHD of 90 mg/m 2 /day in patients with cancer). These studies have revealed no evidence of teratogenicity due to delta-9-THC. At these dronabinol dosages in mice and rats, delta-9-THC decreased maternal weight gain and number of viable pups and increased fetal mortality and early resorptions. Such effects were dose dependent and less apparent at lower doses that produced less maternal toxicity. Review of published literature indicates that the endocannabinoid system plays a role in neurodevelopmental processes such as neurogenesis, migration, and synaptogenesis. Exposure of pregnant rats to delta-9-THC (during and after organogenesis) may modulate these processes to result in abnormal patterns of neuronal connectivity and subsequent cognitive impairments in the offspring. Nonclinical toxicity studies in pregnant rats and newborn pups have shown prenatal exposure to delta-9-THC that resulted in impairment of motor function, alteration in synaptic activity, and interference in cortical projection of neuron development in the offspring. Prenatal exposure has shown effects on cognitive function such as learning, short-and long-term memory, attention, decreased ability to remember task, and ability to discriminate between novel and same objects. Overall, prenatal exposure to delta-9-THC has resulted in significant and long-term changes in brain development, cognition, and behavior in rat offspring. In a pre- and postnatal development study, female rats were administered dronabinol by oral gavage at doses of 0.5, 5, or 15 mg/kg/day (equivalent to 0.2, 2, and 6 times the MRHD for patients with AIDS and 0.03, 0.33, and 1.0 times the MRHD for patients with cancer, respectively, based on body surface area) from gestation day 6 (implantation) through lactation day 20 (weaning). Maternal toxicity including adverse clinical signs (i.e., decreased motor activity, low carriage, abnormal gait, hunched posture, vocalization to touch, ungroomed coat, mild dehydration, piloerection, and splayed hindlimbs), reduced body weight and body weight gain, and decreased food consumption were observed during the gestation period at 2 and 6 times the MRHD for patients with AIDS and 0.33 and 1.0 times the MRHD for patients with cancer, respectively. At the same doses, reduced pup bodyweight, increased stillbirths, and mortality of offspring were observed. No neurodevelopmental adverse effects (i.e., neurobehavioral function, sensory function, motor activity, learning and memory) were observed in pups at maternal doses up 15 mg/kg/day (6 times the MRHD in patients with AIDS or 1.0 times the MRI-ID in patients with cancer). 8.2 Lactation Risk Summary For mothers infected with the Human Immunodeficiency Virus (HIV), the Centers for Disease Control and Prevention recommends that HIV-infected mothers not breastfeed their infants to avoid risking postnatal transmission of HIV. Because of the potential for HIV transmission (in HIV-negative infants) and serious adverse reactions in a breastfed infant, instruct mothers not to breastfeed if they are receiving dronabinol capsules.

ion recommends that HIV-infected mothers not breastfeed their infants to avoid risking postnatal transmission of HIV. Because of the potential for HIV transmission (in HIV-negative infants) and serious adverse reactions in a breastfed infant, instruct mothers not to breastfeed if they are receiving dronabinol capsules. For mothers with nausea and vomiting associated with cancer chemotherapy, there are limited data on the presence of dronabinol in human milk, the effects on the breastfed infant, or the effects on milk production. The reported effects of inhaled cannabis transferred to the breastfeeding infant have been inconsistent and insufficient to establish causality. In rat offspring exposed to dronabinol in utero and during lactation, reduced bodyweight was observed during the preweaning (lactation) stage with maternal administration of dronabinol at 2 times and less than the MRHD for patients with AIDS and cancer, respectively. Breastfeeding infants should have their weight monitored. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for dronabinol capsules and any potential adverse effects on the breastfed infant from dronabinol capsules or from the underlying maternal condition. 8.4 Pediatric Use The safety and effectiveness of dronabinol capsules have not been established in pediatric patients. Pediatric patients may be more sensitive to neurological and psychoactive effects of dronabinol capsules [see Warnings and Precautions (5.1) ]. 8.5 Geriatric Use Clinical studies of dronabinol capsules in AIDS and cancer patients did not include the sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Elderly patients may be more sensitive to the neuropsychiatric and postural hypotensive effects of dronabinol capsules [see Warnings and Precautions (5.1 , 5.2) ]. Elderly patients with dementia are at increased risk for falls as a result of their underlying disease state, which may be exacerbated by the CNS effects of somnolence and dizziness associated with dronabinol capsules [see Warnings and Precautions (5.1) ]. These patients should be monitored closely and placed on fall precautions prior to initiating dronabinol capsules therapy. In antiemetic studies, no difference in efficacy was apparent in patients greater than 55 years of age compared to younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of falls, decreased hepatic, renal, or cardiac function, increased sensitivity to psychoactive effects, and of concomitant disease or other drug therapy [see Dosage and Administration (2.1 , 2.2) ]. 8.6 Effect of CYP2C9 Polymorphism Published data suggest that systemic clearance of dronabinol may be reduced and concentrations may be increased in the presence of CYP2C9 genetic polymorphism. Monitoring for potentially increased adverse reactions is recommended in patients known to carry genetic variants associated with diminished CYP2C9 function [see Clinical Pharmacology (12.5) ].

9 DRUG ABUSE AND DEPENDENCE 9.1 Controlled Substance Dronabinol capsules contain dronabinol, a Schedule III controlled substance. 9.2 Abuse Dronabinol capsules contain dronabinol, the main psychoactive component in marijuana. Ingestion of high doses of dronabinol increases the risk of psychiatric adverse reactions if abused or misused, while continued administration can lead to addiction. Psychiatric adverse reactions may include psychosis, hallucinations, depersonalization, mood alteration, and paranoia. In an open-label study in patients with AIDS who received dronabinol capsules for up to five months, no abuse, diversion or systematic change in personality or social functioning were observed despite the inclusion of a substantial number of patients with a past history of drug abuse. Patients should be instructed to keep dronabinol capsules in a secure place out of reach of others for whom the medication has not been prescribed. 9.3 Dependence Physical dependence is a state that develops as a result of physiological adaptation in response to repeated drug use. Physical dependence manifests by drug class-specific withdrawal symptoms after abrupt discontinuation or a significant dose reduction of a drug. The appearance of a withdrawal syndrome when administration of the drug is terminated is the only actual evidence of physical dependence. Physical dependence can develop during chronic therapy with dronabinol capsules, and develops after chronic abuse of marijuana. A withdrawal syndrome was reported after the abrupt discontinuation of dronabinol in subjects receiving dosages of 210 mg per day for 12 to 16 consecutive days. Within 12 hours after discontinuation, subjects manifested symptoms such as irritability, insomnia, and restlessness. By approximately 24 hours post-dronabinol discontinuation, withdrawal symptoms intensified to include "hot flashes," sweating, rhinorrhea, loose stools, hiccoughs, and anorexia. These withdrawal symptoms gradually dissipated over the next 48 hours. Electroencephalographic changes consistent with the effects of drug withdrawal (hyperexcitation) were recorded in patients after abrupt dechallenge. Patients also complained of disturbed sleep for several weeks after discontinuing therapy with high dosages of dronabinol.

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Dronabinol is an orally active cannabinoid which has complex effects on the CNS, including central sympathomimetic activity. Cannabinoid receptors have been discovered in neural tissues. These receptors may play a role in mediating the effects of dronabinol. 12.2 Pharmacodynamics Effects on the Cardiovascular System Dronabinol-induced sympathomimetic activity may result in tachycardia and/or conjunctival injection. Its effects on blood pressure are inconsistent, but subjects have experienced orthostatic hypotension and/or syncope upon abrupt standing [see Warnings and Precautions (5.2) ]. Effects on the Central Nervous System Dronabinol also demonstrates reversible effects on appetite, mood, cognition, memory, and perception. These phenomena appear to be dose-related, increasing in frequency with higher dosages, and subject to great inter-patient variability. After oral administration, dronabinol has an onset of action of approximately 0.5 to 1 hours and peak effect at 2 to 4 hours. Duration of action for psychoactive effects is 4 to 6 hours, but the appetite stimulant effect of dronabinol may continue for 24 hours or longer after administration. Tachyphylaxis and tolerance develop to some of the pharmacologic effects of dronabinol with chronic use, suggesting an indirect effect on sympathetic neurons. In a study of the pharmacodynamics of chronic dronabinol exposure, healthy male subjects (N = 12) received 210 mg per day of dronabinol capsules, administered orally in divided doses, for 16 days. An initial tachycardia induced by dronabinol was replaced successively by normal sinus rhythm and then bradycardia. A decrease in supine blood pressure, made worse by standing, was also observed initially. These subjects developed tolerance to the cardiovascular and subjective adverse CNS effects of dronabinol within 12 days of treatment initiation. Tachyphylaxis and tolerance do not appear to develop to the appetite stimulant effect of dronabinol capsules. In clinical studies involving AIDS patients, the appetite stimulant effect of dronabinol capsules was sustained for up to five months at dosages ranging from 2.5 mg to 20 mg per day. 12.3 Pharmacokinetics Absorption Dronabinol (delta-9-THC) is almost completely absorbed (90 to 95%) after single oral doses. Due to the combined effects of first pass hepatic metabolism and high lipid solubility, only 10 to 20% of the administered dose reaches the systemic circulation. Concentrations of both parent drug and its major active metabolite (11-hydroxy-delta-9-THC) peak at approximately 0.5 to 4 hours after oral dosing and decline over several days. The pharmacokinetics of dronabinol after single doses (2.5, 5, and 10 mg) and multiple doses (2.5, 5, and 10 mg given twice a day) have been studied in healthy subjects. Summary of Multiple-Dose Pharmacokinetic Parameters of Dronabinol in Healthy Subjects (n=34; 20 to 45 years) under Fasted Conditions Mean (SD) PK Parameter Values Twice Daily Dose C max ng/mL Median T max (range), hr AUC (0-12) ng∙hr/mL C max : maximum observed plasma concentration; T max : time to maximum observed plasma concentration; AUC (0-12) : area under the plasma concentration-time curve from 0 to 12 hours.

Effect of Food: In a published study, the effect of food on the pharmacokinetics of dronabinol was studied by concomitant dosing of dronabinol capsules with a high-fat (59 grams of fat, approximately 50% of total caloric content of the meal), high calorie meal (approximately 950 calories). An appreciable food effect was observed, resulting in a 4-hour delay in mean T max and 2.9-fold increase in total exposure (AUC inf ), but C max was not significantly changed [see Dosage and Administration (2.2) ]. Distribution Dronabinol has an apparent volume of distribution of approximately 10 L/kg, because of its lipid solubility. The plasma protein binding of dronabinol and its metabolites is approximately 97% [see Drug Interactions (7.4) ]. Elimination The pharmacokinetics of dronabinol can be described using a two-compartment model with an initial (alpha) half-life of about 4 hours and a terminal (beta) half-life of 25 to 36 hours. Values for clearance average about 0.2 L/kg-hr, but are highly variable due to the complexity of cannabinoid distribution. Metabolism Dronabinol undergoes extensive first-pass hepatic metabolism, primarily by hydroxylation, yielding both active and inactive metabolites. Dronabinol and its principal active metabolite, 11‑hydroxy-delta-9-THC, are present in approximately equal concentrations in plasma. Published in vitro data indicates that CYP2C9 and CYP3A4 are the primary enzymes in the metabolism of dronabinol. CYP2C9 appears to be the enzyme responsible for the formation of the primary active metabolite [see Clinical Pharmacology (12.5) ]. Excretion Dronabinol and its biotransformation products are excreted in both feces and urine. Biliary excretion is the major route of elimination with about half of a radiolabeled oral dose being recovered from the feces within 72 hours as contrasted with 10 to 15% recovered from urine. Less than 5% of an oral dose is recovered unchanged in the feces. Due to its re-distribution, dronabinol and its metabolites may be excreted at low levels for prolonged periods of time. Following single dose administration, low levels of dronabinol metabolites have been detected for more than 5 weeks in the urine and feces. In a study of dronabinol capsules involving AIDS patients, urinary cannabinoid/creatinine concentration ratios were studied bi-weekly over a six-week period. The urinary cannabinoid/creatinine ratio was closely correlated with dose. No increase in the cannabinoid/creatinine ratio was observed after the first two weeks of treatment, indicating that steady-state cannabinoid levels had been reached. This conclusion is consistent with predictions based on the observed terminal half-life of dronabinol. Drug Interaction Studies Formal drug-drug interaction studies have not been conducted with dronabinol. The enzyme inhibition and induction potential of dronabinol and its active metabolite are not completely understood. Published data showed an increase in the elimination half-life of pentobarbital by 4 hours when concomitantly dosed with dronabinol [see Warnings and Precautions (5.1) ].

Published data showed an increase in the elimination half-life of pentobarbital by 4 hours when concomitantly dosed with dronabinol [see Warnings and Precautions (5.1) ]. 12.5 Pharmacogenomics Published data indicate a potentially 2-to 3-fold higher dronabinol exposure in individuals carrying genetic variants associated with diminished CYP2C9 function.

12.3 Pharmacokinetics Absorption Dronabinol (delta-9-THC) is almost completely absorbed (90 to 95%) after single oral doses. Due to the combined effects of first pass hepatic metabolism and high lipid solubility, only 10 to 20% of the administered dose reaches the systemic circulation. Concentrations of both parent drug and its major active metabolite (11-hydroxy-delta-9-THC) peak at approximately 0.5 to 4 hours after oral dosing and decline over several days. The pharmacokinetics of dronabinol after single doses (2.5, 5, and 10 mg) and multiple doses (2.5, 5, and 10 mg given twice a day) have been studied in healthy subjects. Summary of Multiple-Dose Pharmacokinetic Parameters of Dronabinol in Healthy Subjects (n=34; 20 to 45 years) under Fasted Conditions Mean (SD) PK Parameter Values Twice Daily Dose C max ng/mL Median T max (range), hr AUC (0-12) ng∙hr/mL C max : maximum observed plasma concentration; T max : time to maximum observed plasma concentration; AUC (0-12) : area under the plasma concentration-time curve from 0 to 12 hours. 2.5 mg 1.32 (0.62) 1.00 (0.50-4.00) 2.88 (1.57) 5 mg 2.96 (1.81) 2.50 (0.50-4.00) 6.16 (1.85) 10 mg 7.88 (4.54) 1.50 (0.50-3.50) 15.2 (5.52) A slight increase in dose proportionality on mean C max and AUC (0-12) of dronabinol was observed with increasing dose over the dose range studied. Effect of Food: In a published study, the effect of food on the pharmacokinetics of dronabinol was studied by concomitant dosing of dronabinol capsules with a high-fat (59 grams of fat, approximately 50% of total caloric content of the meal), high calorie meal (approximately 950 calories). An appreciable food effect was observed, resulting in a 4-hour delay in mean T max and 2.9-fold increase in total exposure (AUC inf ), but C max was not significantly changed [see Dosage and Administration (2.2) ]. Distribution Dronabinol has an apparent volume of distribution of approximately 10 L/kg, because of its lipid solubility. The plasma protein binding of dronabinol and its metabolites is approximately 97% [see Drug Interactions (7.4) ]. Elimination The pharmacokinetics of dronabinol can be described using a two-compartment model with an initial (alpha) half-life of about 4 hours and a terminal (beta) half-life of 25 to 36 hours. Values for clearance average about 0.2 L/kg-hr, but are highly variable due to the complexity of cannabinoid distribution. Metabolism Dronabinol undergoes extensive first-pass hepatic metabolism, primarily by hydroxylation, yielding both active and inactive metabolites. Dronabinol and its principal active metabolite, 11‑hydroxy-delta-9-THC, are present in approximately equal concentrations in plasma. Published in vitro data indicates that CYP2C9 and CYP3A4 are the primary enzymes in the metabolism of dronabinol. CYP2C9 appears to be the enzyme responsible for the formation of the primary active metabolite [see Clinical Pharmacology (12.5) ]. Excretion Dronabinol and its biotransformation products are excreted in both feces and urine. Biliary excretion is the major route of elimination with about half of a radiolabeled oral dose being recovered from the feces within 72 hours as contrasted with 10 to 15% recovered from urine. Less than 5% of an oral dose is recovered unchanged in the feces. Due to its re-distribution, dronabinol and its metabolites may be excreted at low levels for prolonged periods of time.

out half of a radiolabeled oral dose being recovered from the feces within 72 hours as contrasted with 10 to 15% recovered from urine. Less than 5% of an oral dose is recovered unchanged in the feces. Due to its re-distribution, dronabinol and its metabolites may be excreted at low levels for prolonged periods of time. Following single dose administration, low levels of dronabinol metabolites have been detected for more than 5 weeks in the urine and feces. In a study of dronabinol capsules involving AIDS patients, urinary cannabinoid/creatinine concentration ratios were studied bi-weekly over a six-week period. The urinary cannabinoid/creatinine ratio was closely correlated with dose. No increase in the cannabinoid/creatinine ratio was observed after the first two weeks of treatment, indicating that steady-state cannabinoid levels had been reached. This conclusion is consistent with predictions based on the observed terminal half-life of dronabinol. Drug Interaction Studies Formal drug-drug interaction studies have not been conducted with dronabinol. The enzyme inhibition and induction potential of dronabinol and its active metabolite are not completely understood. Published data showed an increase in the elimination half-life of pentobarbital by 4 hours when concomitantly dosed with dronabinol [see Warnings and Precautions (5.1) ].

13 NONCLINICAL TOXICOLOGY 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility In 2-year carcinogenicity studies, there was no evidence of carcinogenicity in rats at doses up to 50 mg/kg/day dronabinol (approximately 20 times the MRHD in AIDS patients on a body surface area basis) or in mice at doses up to 500 mg/kg/day (approximately 100 times the MRHD in AIDS patients on a body surface area basis). Dronabinol was not genotoxic in the Ames tests, the in vitro chromosomal aberration test in Chinese hamster ovary cells, and the in vivo mouse micronucleus test. However, dronabinol produced a weak positive response in a sister chromatid exchange test in Chinese hamster ovary cells. In a long-term study (77 days) in rats, oral administration of dronabinol at doses of 30 to 150 mg/m 2 , equivalent to 2 to 10 times the MRHD of 15 mg/m 2 /day in AIDS patients or 0.3 to 1.5 times the MRHD of 90 mg/m 2 /day in cancer patients, reduced ventral prostate, seminal vesicle and epididymal weights and caused a decrease in seminal fluid volume. Decreases in spermatogenesis, number of developing germ cells, and number of Leydig cells in the testis were also observed. However, sperm count, mating success, and testosterone levels were not affected. The significance of these animal findings in humans is not known.

14 CLINICAL STUDIES The effectiveness of dronabinol capsules has been established based on studies for the treatment of anorexia associated with weight loss in patients with AIDS and nausea and vomiting associated with cancer chemotherapy in patients who have failed to respond adequately to conventional antiemetic treatments. 14.1 Appetite Stimulation The appetite stimulant effect of dronabinol capsules in the treatment of AIDS-related anorexia associated with weight loss was studied in a randomized, double-blind, placebo-controlled study involving 139 patients. The initial dosage of dronabinol capsules in all patients was 5 mg/day, administered in doses of 2.5 mg one hour before lunch and one hour before dinner. In pilot studies, early morning administration of dronabinol capsules appeared to have been associated with an increased frequency of adverse experiences, as compared to dosing later in the day. The effect of dronabinol capsules on appetite, weight, mood, and nausea was measured at scheduled intervals during the six-week treatment period. Side effects (feeling high, dizziness, confusion, somnolence) occurred in 13 of 72 patients (18%) at this dosage level and the dosage was reduced to 2.5 mg/day, administered as a single dose at supper or bedtime. Of the 112 patients that completed at least 2 visits in the randomized, double-blind, placebo-controlled study, 99 patients had appetite data at 4-weeks (50 received dronabinol capsules and 49 received placebo) and 91 patients had appetite data at 6-weeks (46 received dronabinol capsules and 45 received placebo). A statistically significant difference between dronabinol capsules and placebo was seen in appetite as measured by the visual analog scale at weeks 4 and 6 (see figure). Trends toward improved body weight and mood, and decreases in nausea were also seen. After completing the 6-week study, patients were allowed to continue treatment with dronabinol capsules in an open-label study, in which there was a sustained improvement in appetite. Figure
