Course Summary
Beta blockers are used mainly in the treatment of heart failure, angina pectoris, and tachyarrhythmias. Other off-label uses of beta-blockers include the management of migraine headaches, performance anxiety, glaucoma, as well as other disorders. The use of beta-blockers has wide acceptance for the management of cardiovascular disorders and provides protective benefits for ischemic heart diseases with regard to morbidity and mortality. Their uses in patients with asthma and COPD is controversial. Beta-blockers may pose a risk in patients with severe COPD but may also be effective for patients with mild to moderate asthma or COPD. Pharmacists and pharmacy technicians should have a system in place to signal or alert them of patients with asthma or COPD, as well as the severity of these conditions, when these patients are prescribed beta-blockers. This course will discuss how prescriptions for beta-blockers should be made, the risks and benefits of beta-blockers and when and how they must be balanced.
Course Objectives
  • Identify the indications, uses, contraindications and potential side effects of beta-blockers
  • Compare the use of beta-blockers, including off-label uses, in multiple clinical settings
