Beta-blockers, as a class of drugs, are primarily used to treat cardiovascular diseases and other conditions. Beta-blockers are indicated and have FDA approval for the treatment of tachycardia, hypertension, myocardial infarction, congestive heart failure, cardiac arrhythmias, coronary artery disease, hyperthyroidism, essential tremor, aortic dissection, portal hypertension, glaucoma, migraine prophylaxis, and other conditions. They are also used to treat less common conditions such as long QT syndrome and hypertrophic obstructive cardiomyopathy. This activity outlines the indications, mechanism of action, safe administration, adverse effects, contraindications, toxicology, and monitoring of the broad array of physiological possibilities when using beta-blockers in the clinical setting. Objectives: Summarize the mechanism of action of the beta-blocker class of medications, including the difference between selective and non-selective agents. Identify the indications for beta-blocker therapy. Review the adverse events, contraindications, toxicities, and interactions of beta-blockers. Outline the importance of improving care coordination among the interprofessional team to improve outcomes for patients using beta-blockers for indicated conditions.

The antidote for beta-blocker overdose is glucagon. It is especially useful in beta-blocker-induced cardiotoxicity. The second line of treatment is cardiac pacing if glucagon fails, and this may include transcutaneous pacing or transvenous pacing. Potential acute toxicity can be mitigated by using extended-release formulations as a preventative strategy, which will delay peak toxicity.[13] Please see StatPearls' companion topic, "Beta-Blocker Toxicity," for an in-depth discussion on the potential toxicity associated with beta-blockers.

Beta-blockers are a broad class of medications that are used for various clinical benefits but also carry the potential for adverse effects. They are prescribed by clinicians (MDs, DOs, NPs, or PAs) in both outpatient and inpatient settings, largely for the treatment of cardiovascular-related illnesses. When a patient is admitted to an inpatient ward, monitoring the clinical effects and potential adverse effects is an interprofessional task. This is crucial because excessively high serum levels can have serious or even fatal consequences. Nurses will generally be the first caregivers to take note of any unwanted effects, such as a change in vital signs. In contrast, outpatient settings differ in that the pharmacist may be the closest line of healthcare contact for a patient. The pharmacist will dispense the medication, perform medication reconciliation, verify dosing, and also advise other interprofessional team members and the patient of any potential adverse effects. It is also imperative to take note of any patients who are currently on beta-blockers, as it provides a clinical context for potential symptoms. Many clinical trials have been conducted on beta-blockers and shown to prolong life in patients with cardiovascular disease.[14][15][16] [Level 2] The interprofessional healthcare team needs to prescribe, manage, and monitor the use of beta-blockers safely and effectively.
