Abstract

The invention relates to an Azilsartan tablet and a preparation method thereof. The Azilsartan tablet contains micronized Azilsartan, lactose anhydrous 21AN, lactose anhydrous 24AN, a disintegrating agent, and a lubricant, and is prepared by pressing through adopting tabletting technology. Compared with the prior art, the Azilsartan tablet is fast in dissolving speed, simple in technology, and an acceleration test result shows that the prepared Azilsartan tablet has good stability.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to an azilsartan tablet and a preparation method thereof. Background technique [0002] Azilsartan is an angiotensin II receptor antagonist drug for the treatment of hypertension. It is mostly used for the treatment of hypertension. It is also the only angiotensin II receptor antagonist (sartan) drug in the terminal clinical stage. . The drug was launched by Japan's Takeda Pharmaceutical Company in 2012, and its clinical efficacy is remarkable. [0003] Azilsartan is a poorly soluble drug with a solubility in water of less than 9 μg / ml. The structure is as follows: [0004] [0005] The bioavailability of a drug in the body is greatly affected by the dissolution of the drug. Azilsartan is almost insoluble in water and is a poorly soluble drug. When making pharmaceutical preparations, micronized azilsartan particles are often used, and the particle size is control...
