Abbreviated New Drug Application
BISOPROLOL FUMARATE- BISOPROLOL FUMARATE TABLET, FILM COATED AVPAK ---------- BISOPROLOL FUMARATE TABLETS, USP RX ONLY DESCRIPTION Bisoprolol fumarate is a synthetic, beta -selective (cardioselective) adrenoceptor blocking agent. The chemical name for bisoprolol fumarate is (±)-1-[4-[[2-(1- Methylethoxy)ethoxy]methyl]phenoxy]-3-[(1-methylethyl)amino]-2-propanol( _E_)-2- butenedioate (2:1) (salt). It possesses an asymmetric carbon atom in its structure and is provided as a racemic mixture. The S(-) enantiomer is responsible for most of the beta- blocking activity. Its molecular formula is (C H NO ) •C H O and its structure is: Bisoprolol fumarate has a molecular weight of 766.97. It is a white crystalline powder which is approximately equally hydrophilic and lipophilic, and is readily soluble in water, methanol, ethanol, and chloroform. Bisoprolol fumarate is available as 5 and 10 mg tablets for oral administration. Inactive ingredients include microcrystalline cellulose, anhydrous dibasic calcium phosphate, crospovidone, colloidal silicon dioxide, magnesium stearate, hypromellose, polyethylene glycol, polysorbate 80, and titanium dioxide. The 5 mg tablets also contain red and yellow iron oxide. CLINICAL PHARMACOLOGY Bisoprolol fumarate is a beta -selective (cardioselective) adrenoceptor blocking agent without significant membrane stabilizing activity or intrinsic sympathomimetic activity in its therapeutic dosage range. Cardioselectivity is not absolute, however, and at higher doses (≥20 mg) bisoprolol fumarate also inhibits beta -adrenoceptors, chiefly located in the bronchial and vascular musculature; to retain selectivity it is therefore important to 1 18 31 4 2 4 4 4 1 2 use the lowest effective dose. PHARMACOKINETICS AND METABOLISM The absolute bioavailability after a 10 mg oral dose of bisoprolol fumarate is about 80%. Absorption is not affected by the presence of food. The first pass metabolism of bisoprolol fumarate is about 20%. Binding to serum proteins is approximately 30%. Peak plasma concentrati Leer el documento completo
