Abstract

The invention provides a preparation method of succinic acid Trelagliptin tablets. The method includes: taking succinic acid Trelagliptin, adding sorbitol, microcrystalline cellulose and crosslinking sodium carboxymethyl cellulose, mixing, placing mixture under a condition with certain temperature and relative humidity, moving into a vacuum kettle, rising the temperature under a vacuum condition, adding binder, performing wet granulation, drying obtained granules in a fluidized bed granulation coating machine to obtain dried granules, adding lubricant into the dry granules, mixing, tableting, and coating to obtain the succinic acid Trelagliptin tablets. The preparation method has the advantages that the succinic acid Trelagliptin tablets prepared by the method is stable in quality and good in in-vitro dissolution performance, the method is simple in production process, and large-scale industrial production can be achieved.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a preparation method of trexagliptin succinate tablet. Background technique [0002] Diabetes is currently the top five leading cause of death worldwide. Especially in Asia, the number and compound growth rate of diabetic patients will rise rapidly. Although there are many types of diabetes drugs on the market, experts point out that with the progression of type 2 diabetes, the function of pancreatic beta cells gradually declines or even fails. The hypoglycemic efficacy of traditional treatments, whether it is insulin secretagogues or sensitizers, depends on the existence of pancreatic β-cell function. Therefore, more and more patients, especially those in the middle and advanced stages, have increasingly difficult to control their blood sugar levels. For such patients, insulin-independent hypoglycemic drugs may provide a more effective treatmen...
