Atazanavir is approved by the U.S. Food and Drug Administration (FDA) for the treatment of HIV-1 infection in both treatment-naive and treatment-experienced patients. This medication is prescribed in combination with other antiretroviral agents for individuals aged 3 months and older with a body weight of 5 kg or more. Atazanavir belongs to the protease inhibitor class of HIV-1 medications and is occasionally used off-label for HIV postexposure prophylaxis in situations involving potential exposure, such as needle sticks. This activity highlights the indications, mechanism of action, administration, adverse effects, contraindications, and monitoring for atazanavir, providing relevant information for healthcare team members involved in the management of HIV/AIDS infection. Objectives: Identify the appropriate indications for atazanavir in the treatment of HIV-1 infection, considering both treatment-naive and treatment-experienced patients. Screen patients for eligibility based on age, body weight, and specific criteria outlined for atazanavir therapy. Assess patients for symptoms of adverse reactions promptly, recognizing the potential for rapid escalation to life-threatening situations. Collaborate with other healthcare team members to enhance awareness and understanding of atazanavir, fostering a coordinated approach to patient care.

Currently, no specific antidote exists for atazanavir toxicity. Patients should receive symptomatic and supportive care from healthcare staff while regularly monitoring their vital signs and looking for signs of respiratory distress. Electrocardiogram monitoring of the patient is recommended, as atazanavir may exacerbate AV block due to PR interval prolongation. In cases where a simultaneous overdose with nucleoside reverse transcriptase inhibitors is suspected, clinicians should carefully monitor patients for symptoms of lactic acidosis.[36]

Estimates indicate that more than a million people in the United States are living with HIV infection. Upon diagnosis of HIV infection, the recommended course is the prompt initiation of antiretroviral treatment to delay disease progression from HIV infection to AIDS. This approach necessitates a collaborative effort from an interprofessional healthcare team, including physicians or specialists, advanced practice practitioners, nursing staff, and pharmacists. Adherence to the treatment plan is equally crucial to prevent HIV transmission to others by reducing viral load.[37] Moreover, studies have indicated that the stigma associated with HIV infection negatively influences treatment adherence.[26] This factor poses a non-trivial challenge to the entire healthcare team, encompassing the need to monitor patients for adverse drug events to enhance adherence to drug therapy, conduct tests for the occurrence of drug resistance, and deliver effective counseling on the significance of therapy adherence and behavioral modifications. The overarching goal is to mitigate patients' risk for opportunistic infections and minimize the public risk of HIV spread. Treatment adherence is improved by the healthcare team when they address patient concerns about adverse events, offer strategies to mitigate dosing forgetfulness, and promote disease and health literacy. Recent research has demonstrated that a single-tablet regimen enhances pharmaceutical adherence compared to multiple-tablet regimens.[38] Nursing staff are crucial in conducting patient counseling to underscore the importance of strict regimen adherence. A lapse in this aspect can potentially render entire classes of antiretroviral drugs ineffective. Pharmacists with specialized expertise, preferably holding infectious disease board certification and additional specialization in HIV regimens, should verify the chosen agents and dosages, thoroughly assess potential drug interactions that may result in adverse effects or compromise therapeutic effectiveness, and promptly communicate any identified issues to the prescriber. In summary, interprofessional healthcare teams can enhance HIV treatment outcomes by improving drug therapy adherence by educating patients, carefully monitoring their symptoms, and considering patients' requirements and lifestyles.
