Abstract

The invention belongs to the medical technicial field, and discloses an amlodipine besylate composition which comprises the following components in parts by weight: 3-6 parts by weight of amlodipine besylate, 1-1.8 parts by weight of a disintegrating agent, 65-70 parts by weight of a filler, 20-25 parts by weight of polyethylene glycol 600, and 0.05-0.1 part by weight of a lubricant. An amlodipine besylate tablet is prepared, the 5 min dissolution rate can reach up to more than 80%, the content of stability testing total impurities is less than 0.30%, the amlodipine besylate tablet having stable main drug content and high bioavailability is prepared, and besides, the preparation process has the advantages of being simple to operate, low in equipment requirement, low in production cost and suitable for industrialized production.

Description

technical field [0001] The invention relates to the field of medicine, in particular to an amlodipine besylate composition. Background technique [0002] Calcium antagonists (CAS) are recognized effective antihypertensive drugs and arterial dilators, which block Ca 2+ Into the cells, thereby relaxing vascular smooth muscle, expanding peripheral arterioles, reducing peripheral resistance, and lowering blood pressure. In addition, calcium antagonists can also help improve myocardial ischemia and relieve angina by reducing cardiac afterload and increasing coronary blood flow. [0003] Amlodipine besylate is the third-generation 1,4-dihydropyridine calcium ion antagonist successfully developed by Pfizer Pharmaceuticals Co., Ltd. in the mid-1980s. Its chemical name is 3-ethyl-5-methyl- 2-(2-Aminoethoxymethyl)-4-(2-chlorophenyl)-1,4-dihydro-6-methyl-3,5-pyridinedicarboxylate benzenesulfonate. It has mild and long-lasting effects, is convenient to take, and has mild adverse reac...
