Adrenergic beta-receptor blockaders (beta-blockers) are "drugs that bind to but do not activate beta-adrenergic receptors thereby blocking the actions of beta-adrenergic agonists. Adrenergic beta-antagonists are used for treatment of hypertension, cardiac arrhythmias, angina pectoris, glaucoma, migraine headaches, and anxiety".[1]
Beta-blockers vary within the class regarding intrinsic sympathomimetic activity (ISA), beta 1-selectivity, membrane stabilizing activity, lipophilicity, and metabolism. This may lead to different effectiveness among this class of drugs. A meta-analysis has concluded that metoprolol may be the best beta-blocker for secondary prevention of myocardial infarction.[2]
