Influence of ayurvedic antidiabetic agent on the pharmacodynamics of glimepiride

Abstract

The present study is planned to explore the influence of ayurvedic antidibetic drug Madhumehari on the pharmacodynamics of glimepiride. Wistar albino rats of either sex were induced diabetes with alloxan and were used. The study was done in two phases, acute phase and chronic phase. In acute phase the diabetic rats were divided into six groups each consisting of 6. The diabetic control (Group-I) was treated with 0.5%W/V CMC suspension orally. To the diabetic group II, III and IV glimepiride 4mg/kg body wt, madhumehari 100mg/kg body wt. and madhumehari 200mg/kg body wt. were administered orally respectively.   Groups V and VI were given orally the combination of glimepiride 4mg/kg body wt + madhumehari 100mg/kg body wt and glimepiride 4mg/kg body wt + madhumehari 200mg/kg body wt. In chronic study the protocol was similar to that of acute study but treatment was given for 7 days. Blood samples were collected from retro orbital plexus at predetermined time intervals for serum glucose level estimation after the oral dosing of glimepiride.  The combination of glimepiride + madhumehari has shown antidiabetic activity at 3^rd hour. Glimepiride when administered along with madhumehari 100 & 200mg orally the fall in serum glucose level was found to be more significant when compared with the per se treatment of  glimepiride, madhumehari 100 & 200mg in both acute and chronic studies. From the above study it may be concluded that there is additive type of Pharmacodynamic interaction is possible between glimepiride and madhumehari.
