Abstract

The invention relates to an irbesartan tablet and a preparation method thereof. The irbesartan tablet is prepared from the following raw materials in parts by mass: 150-450 parts of irbesartan, 15-50 parts of montmorillonite, 85-270 parts of sucrose, 0.5-1.5 parts of magnesium stearate and 0.5-1.5 parts of silicon dioxide. The invention also provides a preparation method of the irbesartan tablet. The irbesartan tablet disclosed by the invention, by matching special accessories and main drugs and through special proportions, can be used for solving the problems of existing drug particles which are poor in liquidity, non-ideal in drug disintegration, low in drug dissolution, poor in stability, not high in bioavailability in human body and the like.

Description

technical field [0001] The invention relates to an irbesartan tablet and a preparation method thereof, belonging to the technical field of medicine. Background technique [0002] According to the statistics of hypertension in China in 2002, the prevalence of hypertension among adults in my country has reached 18.8%, and the total number of people with hypertension in the country has reached nearly 160 million. Various complications caused by hypertension are an important cause of death from cerebrovascular diseases. Therefore, how to effectively prevent and treat hypertension and reduce or reduce various complications caused by hypertension is an important measure to improve the quality of our population and reduce the mortality rate of cardiovascular and cerebrovascular diseases. [0003] Irbesartan is an angiotensin Ⅱ (Angiotensin Ⅱ, Ang Ⅱ) receptor inhibitor, which can inhibit the conversion of Ang Ⅰ to Ang Ⅱ, and can specifically antagonize the angiotensin converting en...
