The invention provides an amlodipine besylate tablet and a preparation method thereof, wherein the tablet comprises, by weight, 15-30 parts of amlodipine besylate, 30-60 parts of microcrystalline cellulose, 10-20 parts of L-tyrosine, 15-25 parts of a solubilizer, 15-30 parts of a disintegrant, 5-10 parts of a crospovidone, 2-5 parts of a lubricant, 5-10 parts of an excipient, and 30-50 parts of ethanol. According to the present invention, the tablet has characteristics of slow release, low gastrointestinal side-effect and simple preparation process.

Description

technical field [0001] The invention belongs to the field of medicines, and in particular relates to an amlodipine besylate tablet and a preparation method thereof. Background technique [0002] In recent years, with the improvement of people's living standards, the incidence of hypertension has also been increasing, and high blood pressure can cause damage to the heart, brain, kidneys and other human organs, which in turn lead to cardiovascular diseases. According to surveys, cardiovascular diseases It has become one of the frequent diseases that endanger human health. Research and development of a drug that can effectively treat hypertension has always been the unremitting pursuit of scholars at home and abroad. [0003] Amlodipine besylate is a third-generation dihydropyridine calcium antagonist. The contraction of cardiac muscle and smooth muscle depends on extracellular calcium ions entering cells through specific ion channels. Compared with similar antihypertensive dr...
