Alprenolol is an antihypertensive drug acting as an antiadrenergic blocker of beta receptors (also called "beta-adrenergic blocker" or simply "beta-blocker"). The main effect of beta-blockers consists in a reduction of cardiac activity due to a decreased stimulation of beta-adrenergic receptors: reducing the speed and the contractile force of the myocardium and decreasing the speed of conduction of impulses through the conducting system, and the response of the heart to stress and exercise is reduced.
