Course Summary
Beta-blockers are essential in the treatment of many cardiovascular diseases, including congestive heart failure, myocardial infarction, and tachyarrhythmias. Beta-blockers are also used for migraine prophylaxis, performance anxiety, glaucoma, and various other conditions. They have notable side effects, contraindications, and warnings associated with their use. Pharmacists and staff should be aware of these when determining the appropriateness of beta-blocker therapy. Additionally, pharmacists and staff should note any potential drug interactions when beta-blocker therapy is initiated. This course will review the pharmacologic characteristics of beta-blockers, identify indications for beta-blocker therapy, and highlight adverse reactions, contraindications, warnings, and interactions associated with beta-blocker therapy. Finally, the management of beta-blocker overdose will be discussed.
