How TOPROL-XL Works

Metoprolol is a cardioselective beta₁-adrenergic receptor blocker. At therapeutic plasma concentrations, it preferentially inhibits beta₁-receptors located chiefly in cardiac muscle, resulting in a reduction in heart rate (sinus rate) and a decrease in AV nodal conduction. This selectivity is dose-dependent; at higher concentrations, metoprolol also inhibits beta₂-adrenoreceptors found in bronchial and vascular musculature. The drug lacks intrinsic sympathomimetic activity (ISA). Its antihypertensive effects are attributed to several mechanisms, including competitive antagonism of catecholamines leading to decreased cardiac output, reduced central sympathetic outflow, and suppression of renin secretion.
