Abbreviated New Drug Application
METOPROLOL TARTRATE- METOPROLOL TARTRATE TABLET, FILM COATED PROFICIENT RX LP ---------- METOPROLOL TARTRATE TABLETS, USP RX ONLY 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 USP 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 glycollate, 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 MECHANISM OF ACTION Metoprolol tartrate is a beta -selective (cardioselective) adrenergic receptor blocker. This preferential effect is not absolute, however, and at higher plasma concentrations, metoprolol also inhibits beta -adrenoreceptors, chiefly located in the bronchial and vascular musculature. Clinical pharmacology studies have demonstrated the beta-blocking activity of metoprolol, 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. 1 1 2 Hypertension The mechanism of the antihypertensive effects of beta-blocking agents has not been fully elucidated. However, several possible mechanisms have been proposed: (1) competitive Prečítajte si celý dokument
