Abstract

The invention relates to a capsule containing valsartan and amlodipine besylate, which is prepared from high-dose valsartan and amlodipine besylate, disintegrating agent crospovidone, filling agent microcrystalline cellulose and lubricating agent silicondioxide. The problem that the compound preparation contianing a high dose of valsartan and amlodipine besylate is not easy to disintegrate and dissolve is solved by adopting the conventional process and equipment of powder mixing and direct capsule filling without using special equipment and the bilayer tablet process.

Description

Technical field: [0001] The invention relates to an oral pharmaceutical composition containing valsartan and amlodipine besylate, and relates to an improved technology for an oral solid preparation of a compound preparation of valsartan and amlodipine besylate. Background technique: [0002] The incidence of hypertension remains high, and there are about one billion hypertensive patients in the world. Blood pressure cannot be controlled within the range of the target value, which can induce cardiovascular disease, kidney disease and metabolic disease. Controlling blood pressure levels can effectively reduce the incidence and mortality of cardiovascular events. Although various antihypertensive drugs are currently on the market, 40% to 80% of hypertensive patients still cannot achieve the prescribed blood pressure control target value, mainly due to poor patient compliance or insufficient medication. Current treatment guidelines recommend the use of compound preparations to...
