The poorly water soluble drugs tend to have low bioavailability and this can be improved by several methods. Solid dispersion is a promising formulation approach to improve solubility and dissolution and ultimately oral bioavailability of these drugs. The aim of this study was to prepare and characterize solid dispersion of anti-diabetic glimepiride, a BCS class II drug, with the hydrophilic carrier PVP K30 by solvent evaporation and microwave induced fusion methods. Scanning electron microscopy (SEM), X–ray powder diffractometry (XRD) and differential scanning calorimetric (DSC) were used to evaluate the physical state of the drug. The solid dispersions were also evaluated for drug content, solubility and dissolution studies. Solid dispersions prepared by solvent evaporation method were showed maximum enhancement of solubility and dissolution in comparison to that prepared by other method.
