Evaluation of anti-diabetic effects of Glimepiride/metformin cocrystal

Emerging data suggest that cocrystal of two compounds may have a different pharmacological effect from two compounds alone or their physical combination. Glimepiride (Gli) and metformin (Met) are two types of anti-diabetic drugs. Previously we generated the glimepiride/metformin cocrystal (GM). In this study, we evaluated the anti-diabetic effects of GM and explored the underlying mechanisms. Our result showed that GM reduced the blood glucose and HbA1c levels in db/db mice, and low doses of GM can achieve the hypoglycemic effect as Gli or Met alone, and high dose of GM was better than Gli and Met alone in improving the pathological changes of liver.
