Abbreviated New Drug Application
LABETALOL HCL- LABETALOL HCL TABLET, FILM COATED MYLAN INSTITUTIONAL INC. ---------- LABETALOL HYDROCHLORIDE TABLETS USP RX ONLY DESCRIPTION Labetalol hydrochloride tablets USP are an adrenergic receptor blocking agent that has both selective alpha -adrenergic and nonselective beta-adrenergic receptor blocking actions in a single substance. Labetalol hydrochloride is a racemate, chemically designated as 2-hydroxy-5-[1-hydroxy-2-[(1-methyl- 3-phenylpropyl)amino]ethyl] benzamide monohydrochloride, and it has the following structure: Labetalol hydrochloride has the molecular formula C H N O •HCl and a molecular weight of 364.87. It has two asymmetric centers and therefore exists as a molecular complex of two diastereoisomeric pairs. Dilevalol, the R,R’ stereoisomer, makes up 25% of racemic labetalol. Labetalol hydrochloride is a white or off-white crystalline powder, soluble in water. Labetalol hydrochloride tablets USP, for oral administration, contain 100 mg, 200 mg or 300 mg labetalol hydrochloride USP. In addition, each tablet contains the following inactive ingredients: corn starch, hypromellose, lactose monohydrate, magnesium stearate, polyethylene glycol, polysorbate, sodium starch glycolate (potato) and titanium dioxide. CLINICAL PHARMACOLOGY Labetalol hydrochloride combines both selective, competitive, alpha -adrenergic blocking and nonselective, competitive, beta-adrenergic blocking activity in a single substance. In man, the ratios of alpha- to beta-blockade have been estimated to be approximately 1:3 and 1:7 following oral and intravenous (IV) administration, respectively. Beta -agonist activity has been demonstrated in animals with minimal beta -agonist (ISA) activity detected. In animals, at doses greater than those required for alpha- or beta-adrenergic blockade, a membrane-stabilizing effect has been demonstrated. PHARMACODYNAMICS 1 19 24 2 3 1 2 1 The capacity of labetalol hydrochloride to block alpha receptors in man has been demonstrated by attenuation of the pressor effect of phenylephrine an সম্পূর্ণ নথি পড়ুন
