Abstract

The present invention relates to a kind of slow released preparation containing metformin hydrochloride and rosiglitazone and its preparation process. The preparation consists of slow released metformin hydrochloride and quickly released rosiglitazone. The extracorporeal leaching test shows that rosiglitazone is released in over 75 % in 30 min. The metformin hydrochloride is released in 15-40 % in the first 1 hr, 50-70 % in the first 4 hr, and over 75 % in the first 8 hr. The slow released preparation containing metformin hydrochloride and rosiglitazone has mild and lasting blood sugar reduction, capacity of avoiding hypoglycemia, gastrointestinal discomfort and other untoward reaction, decreased medicine taking times and raised compliance. The present invention also discloses the extracorporeal slow releasing characteristic and preparation process of the slow released preparation.

Description

technical field [0001] The invention relates to a compound preparation composed of two hypoglycemic drugs rosiglitazone and metformin hydrochloride, a compound sustained-release preparation for treating type II diabetes that cannot effectively control blood sugar by diet control and exercise and a preparation method thereof . Background technique [0002] This compound is composed of two hypoglycemic drugs, but their mechanism of action is different. The two complement each other. [0003] Metformin hydrochloride does not promote insulin secretion. Its hypoglycemic effect is mainly to promote the uptake of glucose by adipose tissue, increase the anaerobic glycolysis of muscle tissue, increase the utilization of glucose, and reduce the absorption of glucose through the digestive tract. [0004] Rosiglitazone has the effect of lowering blood sugar by increasing the sensitivity of tissues to insulin and improving the utilization of glucose by cells. It can significantly reduc...
