Problems solved by technology

In the original research product mentioned above, due to the use of special equipment, the production process is responsible. If metformin and vildagliptin are mixed with wet granulation, the related substances will increase greatly due to the contact with water in the process; if metformin is dry granulated alone, and The compressibility of metformin cannot be improved. If fillers such as microcrystalline cellulose are added to improve its compressibility, since microcrystalline cellulose and other moisture are high and difficult to remove during drying, the growth of impurities during the storage stability process is relatively large. quick

Abstract

The invention provides a preparation method of a composition containing vildagliptin and metformin. The method includes: S1) dissolving 1-10 parts by weight of an adhesive in water and / or an alcohol solvent to obtain a granulation solution; S2) subjecting 5-95 parts by weight of metformin and / or pharmaceutically acceptable salt thereof and the granulation solution to fluidization granulation and drying, then adding 1-5 parts by weight of vildagliptin and / or pharmaceutically acceptable salt thereof and 1-5 parts by weight of a lubricant, mixing the substances uniformly, and conducting tabletting to obtain the composition containing vildagliptin and metformin. Compared with the prior art, the invention adopts fluidization granulation and simplifies the production procedure, at the same timefluidization granulation improves the raw material fluidity, and the obtained particles are loose, thus increasing compressibility. In addition, vildagliptin and pharmaceutically acceptable salts thereof are not added in the granulation process, thus lowering process impurities.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a composition containing vildagliptin and metformin and a preparation method thereof. Background technique [0002] Vildagliptin is a selective, competitive and reversible DPP-4 inhibitor. Vildagliptin inhibits the activity of this enzyme by combining with DPP-4 to form a DPP-4 complex. It increases the concentration of GLP-1 and promotes the production of insulin by pancreatic B cells, while reducing the concentration of glucagon, thereby reducing blood sugar. and had no significant effect on body weight. The vildagliptin metformin compound tablet combines the advantages of the classic hypoglycemic drug metformin and the new dipeptidyl peptidase 4 (DPP-4) inhibitor vildagliptin, which can synergistically increase the level of GLP-1 and regulate the function of islet cells , reduce weight, and contribute to safe and effective blood sugar manageme...
