Problems solved by technology

[0004] The main features of type 2 diabetes are insulin resistance and pancreatic β-cell dysfunction. Therefore, any of the above drugs alone cannot achieve ideal blood sugar control
Analysis of its examples shows that the proportion of the drug-containing coating layer is very large, which is difficult to achieve in the production process, and the uneven coating will also cause problems such as drug flushing; Risk of impurities from active ingredient exposure
[0006] Patent CN201220120673.7 discloses the tablet capsule of the above-mentioned compound preparation, but the process is cumbersome, the energy consumption is large, and the production cost is increased

Abstract

The invention provides a composition containing alogliptin and pioglitazone. The composition comprises 13-33wt% of tablet core, 0.4-10wt% of isolation coating layer and 60-85wt% of outer layer, wherein when the tablet core contains alogliptin, the outer layer contains pioglitazone; when the tablet core contains pioglitazone, the outer layer contains alogliptin; alogliptin accounts for 2.5-10wt% of the total tablet and pioglitazone accounts for 3-16wt% of the total tablet. The composition has the advantages of simple and reliable production process, low loss, good product stability and few by-products, so that the composition is beneficial to large-scale industrial production.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, in particular to a core-coated tablet containing alogliptin and pioglitazone. Background technique [0002] Alogliptin is a DPP-4 (dipeptidyl peptidase-4) inhibitor, which can promote postprandial insulin secretion and inhibit glucagon secretion, and is suitable for the treatment of type 2 diabetes. [0003] Pioglitazone is a thiazolidinedione hypoglycemic agent and an insulin activator for patients with type 2 diabetes. [0004] The main features of type 2 diabetes are insulin resistance and pancreatic β-cell dysfunction. Therefore, any one of the above drugs alone cannot achieve ideal blood sugar control. The effect of combining the two drugs is better, but there is a problem of poor stability. [0005] The compound tablet of alogliptin and pioglitazone (trade name: Oseni) was developed and launched in 2011 by Japan's Takeda Pharmaceutical Co., Ltd. Its patent information is disclo...
