Metoprolol tartrate tablets and injection are indicated in the treatment of hemodynamically stable patients with definite or suspected acute myocardial infarction to reduce cardiovascular mortality. Treatment with intravenous metoprolol tartrate can be initiated as soon as the patient’s clinical condition allows (seeDOSAGE AND ADMINISTRATION ,CONTRAINDICATIONS , andWARNINGS ). Alternatively, treatment can begin within 3 to 10 days of the acute event (seeDOSAGE AND ADMINISTRATION ). Metoprolol tartrate is contraindicated in sinus bradycardia, heart block greater than first degree, cardiogenic shock, and overt cardiac failure (seeWARNINGS ). Hypersensitivity to metoprolol and related derivatives, or to any of the excipients; hypersensitivity to other beta-blockers (cross s

CLINICAL PHARMACOLOGY Metoprolol tartrate is a beta-adrenergic receptor blocking agent. _In vitro _and _in vivo _animal studies have shown that it has a preferential effect on beta adrenoreceptors, chiefly located in cardiac muscle. This preferential effect is not absolute, however, and at higher doses, metoprolol also inhibits beta adrenoreceptors, chiefly located in the bronchial and vascular musculature. Clinical pharmacology studies have confirmed the beta-blocking activity of metoprolol in man, as shown by (1) reduction in heart rate and cardiac output at rest and upon exercise, (2) reduction of systolic blood pressure upon exercise, (3) inhibition of isoproterenol-induced tachycardia, and (4) reduction of reflex orthostatic tachycardia. Relative beta selectivity has been confirmed by the following: (1) In normal subjects, metoprolol is unable to reverse the beta -mediated vasodilating effects Διαβάστε το πλήρες έγγραφο
