PRESCRIPTION DRUG
Metoprolol tartrate tablets are indicated in the long-term treatment of angina pectoris. Metoprolol tartrate tablets are indicated in the treatment of hemodynamically stable patients with definite or suspected acute myocardial infarction to reduce cardiovascular mortality. Treatment with intravenous metoprolol can be initiated as soon as the patient's clinical condition allows (see DOSAGE AND ADMINISTRATION, CONTRAINDICATIONS, and WARNINGS ). Alternatively, treatment can begin within 3 to 10 days of the acute event (see DOSAGE AND ADMINISTRATION). Hypersensitvity to metoprolol and related derivatives, or to any of the excipients; hypersensitivity to other beta-blockers (cross sensitivity between beta-blockers can occur). Sick-sinus syndrome. Severe peripheral arterial circulatory disorders. Metoprolol tartrate tablets are contraindicated in patients with a heart rate < 45 beats/min; second- and third-degree heart block; significant first-degree heart block (P-R interval ≥ 0.24 sec); systolic blood pressure <

Abbreviated New Drug Application
METOPROLOL TARTRATE - METOPROLOL TARTRATE TABLET, FILM COATED AUROLIFE PHARMA LLC ---------- DESCRIPTION Metoprolol tartrate USP is a selective beta -adrenoreceptor blocking agent, available as 25, 50 and 100 mg tablets for oral administration. Metoprolol tartrate is (±)-1-(isopropylamino)-3-[_p_-(2- methoxyethyl)phenoxy]-2-propanol (2:1) _dextro_-tartrate salt. Its structural formula is: Metoprolol tartrate is a white, practically odorless, crystalline powder with a molecular weight of 684.82. It is very soluble in water; freely soluble in methylene chloride, in chloroform, and in alcohol; slightly soluble in acetone; and insoluble in ether. Each tablet for oral administration contains 25 mg, 50 mg or 100 mg of metoprolol tartrate. The tablets contain the following inactive ingredients: microcrystalline cellulose, corn starch, sodium starch glycolate, colloidal silicon dioxide, sodium lauryl sulfate, talc, magnesium stearate, hypromellose, titanium dioxide, polyethylene glycol and polysorbate 80. In addition, 50 mg tablet contains D&C Red #30 Aluminium Lake and 100 mg tablet contains FD&C Blue #2 Aluminium Lake as coloring agents. 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 vasodi Կարդացեք ամբողջական փաստաթուղթը
