Abstract

The invention discloses azilsartan tablets and a preparation process thereof. The tablets comprise azilsartan, microcrystalline cellulose KG1000 and other pharmaceutically acceptable auxiliary materials and are prepared by pressing by adopting a dry-process direct tabletting process. According to the preparation, the content of azilsartan is uniform, and drugs are rapidly dissolved out within 5 minutes. In addition, the preparation process of the preparation is simple, raw materials are not needed to be specially crushed, the granularity requirement is not strict, complex preparation equipment is not needed, and large-scale industrial production is easily realized.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a solid oral preparation, in particular to a tablet containing azilsartan and a preparation process 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 and is currently the only angiotensin II receptor antagonist (sartan) drug in the late clinical stage. . The drug was launched by Japan's Takeda Pharmaceutical Company in 2012, and its efficacy in the clinical stage is remarkable. [0003] Azilsartan's chemical name is 2-ethoxy-1-[[2'-(4,5-dihydro-5-oxo-1,2,4-oxadiazol-3-yl ) biphenyl-4-yl] methyl] benzimidazole-7-carboxylic acid, almost insoluble in water, belongs to insoluble medicine, and the solubility in water is less than 9 μ g / ml, and its chemical structural formula is as follows: [0004] [0005] Because a...
