FORMULATION AND EVALUATION OF LIPID BASED SELF EMULSIFYING DRUG DELIVERY SYSTEM OF GLIMEPIRIDE

Aim of the present investigation was to develop lipid based self-emulsifying drug delivery system(SEDDS) to improve bioavailability of glimepiride. Glimepiride is a class II molecule according to BCS(Biopharmaceutical Classification System), having low solubility. Optimized self-emulsifying drug deliverysystem of glimepiride comprising oil (oleic acid), surfactant (Tween 80) and co-surfactant (PEG 200)was prepared. Optimized SEDDS of glimepiride showed increase in dissolution rate. It was concludedthat the formulation was found to be showing significant improvement in terms of the drug releasewith complete release of drug within 18 minutes. Thus, self-emulsifying formulation of glimepiride wassuccessfully developed.
