Toprol-XL is a beta1-selective (cardioselective) adrenoceptor blocking agent, for oral administration, available as extended release tablets. It has been formulated to provide a controlled and predictable release of metoprolol for once-daily administration. The mechanism of the antihypertensive effects of beta-blocking agents is not fully known. However, several possible mechanisms have been proposed: (1) competitive antagonism of catecholamines at peripheral (especially cardiac) adrenergic neuron sites, leading to decreased cardiac output; (2) a central effect leading to reduced sympathetic outflow to the periphery; and (3) suppression of renin activity. Metoprolol blocks the catecholamine-induced increases in heart rate, velocity and extent of myocardial contraction, and in blood pressure, metoprolol reduces the oxygen requirements of the heart at any given level of effort. Tthe precise mechanism for the beneficial effects of beta-blockers in heart failure is not known. Toprol-XL is specifically indicated for: the treatment of hypertension, either alone or in combination with other antihypertensive agents, the long-term treatment of angina pectoris and the treatment of stable, symptomatic (NYHA Class II or III) heart failure of ischemic, hypertensive, or cardiomyopathic origin. lasix teaching • Hypertension • Angina pectoris • Tachyarrhythmias, in particular supraventricular tachycardia • Maintenance treatment after a myocardial infarction • Prophylaxis of migraine Metoprolol is indicated in adults.
