Investigation on the dissolution rates of glibenclamide and metformin in compound metformin hydrochloride / 第三军医大学学报

ABSTRACT

Objective To investigate the dissolution rates of glibenclamide and metformin in compound metformin hydrochloride. Methods The concentrations of the glibenclamide and metformin were determined by HPLC method. The rotating basket method was used to measure and compare the dissolution rates of glibenclamide and metformin between the compound metformin hydrochloride and conventional tablets. Results The dissolution rates of glibenclamide and metformin with different preparation came up to the standard of CHP (2005), but the dissolution parameters were different. Conclusion The dissolution rate of glibenclamide indicated significant difference between the compound metformin hydrochloride and the conventional tablets, and no significant difference for metformin.
