AMIODARONE HYDROCHLORIDE- AMIODARONE HYDROCHLORIDE TABLET MCKESSON CONTRACT PACKAGING ---------- AMIODARONE HYDROCHLORIDE TABLETS, 200 MG RX ONLY DESCRIPTION Amiodarone hydrochloride tablets are a member of a new class of antiarrhythmic drugs with predominantly Class III (Vaughan Williams’ classification) effects, available for oral administration as yellow, scored tablets. Each tablet for oral administration contains 200 mg of amiodarone hydrochloride. In addition, each tablet contains the following inactive ingredients: colloidal silicon dioxide, corn starch, lactose monohydrate, magnesium stearate, povidone, and D&C yellow No. 10 aluminum lake. Amiodarone hydrochloride tablets are a benzofuran derivative: 2-butyl-3-benzofuranyl 4-[2-(diethylamino)-ethoxy]-3,5-diiodophenyl ketone hydrochloride. It is not chemically related to any other available antiarrhythmic drug. The structural formula is as follows: C H I NO • HCl Molecular Weight: 681.8 Amiodarone hydrochloride is a white to cream-colored crystalline powder. It is slightly soluble in water, soluble in alcohol, and freely soluble in chloroform. It contains 37.3% iodine by weight. CLINICAL PHARMACOLOGY ELECTROPHYSIOLOGY/MECHANISMS OF ACTION In animals, amiodarone hydrochloride is effective in the prevention or suppression of experimentally induced arrhythmias. The antiarrhythmic effect of amiodarone hydrochloride may be due to at least two major properties: 1) a prolongation of the myocardial cell-action potential duration and refractory period and 2) noncompetitive α- and β-adrenergic inhibition. Amiodarone hydrochloride prolongs the duration of the action potential of all cardiac fibers while causing minimal reduction of dV/dt (maximal upstroke velocity of the action potential). The refractory period is prolonged in all cardiac tissues. Amiodarone hydrochloride increases the cardiac refractory period without influencing resting membrane potential, except in automatic cells where the slope of the prepotential is reduced, generally reducing automaticit 전체 문서 읽기
