Introduction The dissolution test as defined in the United States Pharmacopoeia (1) is used in judging the quality of pharmaceutical products. Dissolution testing is a method for evaluating physiological availability that depends upon having the drug in a dissolved state. The USP Dissolution testing involves three stages and the acceptance criteria are defined for each stage as a function of a ...

The aim of the present work was to develop immediate release dosage form of the solid dispersion of glimperide (GLIM) for potential enhancement in the bioavailability. The solid dispersions of GLIM were prepared with PEG6000, PVP K30 and Poloxamer 188, in 1:1, 1:3 and 1:5 %w/w ratio by using solvent wetting and solvent melt method. The in vitro dissolution parameters (%DE10min, %DE30min, %DE60m...
