Abstract

The invention provides a solid compound preparation containing metformin hydrochloride and glimepiride. The solid compound preparation is prepared from metformin hydrochloride granules and glimepiride granules. The metformin hydrochloride granules contain metformin hydrochloride and an adhesive, and the glimepiride granules contain glimepiride, a water soluble filler, a disintegrating agent and an adhesive. The solid compound preparation does not contain water insoluble filler. The invention also provides a preparation method and application of the solid compound preparation. Compared with common preparations and preparations adopting a water insoluble filler, the solid compound preparation provided by the invention can significantly improve the dissolution rate of glimepiride, and can effectively reduce interaction of the two main drugs, thereby reducing the increase of related impurities in a placement process. The product has stable quality and good uniformity, so that the effectiveness and safety of drug use by patients can be improved.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations. Specifically, the invention relates to a solid compound preparation containing metformin hydrochloride and glimepiride, a preparation method and application thereof. Background technique [0002] Both metformin hydrochloride and glimepiride are drugs for the treatment of type Ⅱ diabetes, and their combined application has a synergistic effect, and is suitable for patients who cannot effectively control blood sugar with sulfonylureas alone or who have taken sulfonylureas and metformin at the same time for combined treatment of patients. [0003] The combined application of metformin hydrochloride and glimepiride has been applied and disclosed in domestic and foreign patents, such as the US patent US2003018028A1 applied by the American Wyeth Pharmaceutical Company, the world patent WO9903477A1 applied by the American Smith Kline Pharmaceuticals Company, etc. [0004] A large number of pr...
