Comparative Study of 3 Different Brands of Glimperide

Abstract

Glimepiride is an antidiabetic agent used for lowering blood glucose levels. It induces the activity of peroxisome proliferator-activated receptor-gamma (PPAR gamma). It lowers blood glucose levels by binding to ATP-sensitive potassium channel receptors on the surface of pancreatic cells. The purpose of this study was to perform a comparative analysis of different physicochemical parameters (weight variation, hardness, thickness, friability, disintegration time, and dissolution time) of 3 different commercially available brands of glimepiride in the market. Statistical analysis revealed minor variations in the results. It was found that GETRYL showed the highest % dissolution among all the 3 brands whereas AMARYL took the least time to disintegrate. According to the results of the friability test, Diabold shows the highest stability in the friabilator. However, all 3 brands complied with the official pharmacopoeial limits. The quality of the drug largely influences its therapeutic activity. Hence, owing to the similar physicochemical profile, all the 3 brands can be interchangeably used.
