Abstract

This study aims to prepare immediate release glipizide liquisolid tablets using Avicel PH-102 and Aerosil 200 as the carrier and coating material respectively to increase dissolution rate of poorly soluble glipizide. This study also aims to evaluate treated Gellan gum as disintegrant in the preparation of liquisolid tablets. The solubility of glipizide was increased by use of liquisolid technique. The glipizide liquisolid tablets were evaluated for characteristics like drug content, friability, hardness, disintegration time, thermal analysis, X-ray diffraction (XRD) study and dissolution rates. The dissolution patterns of glipizide liquisolid tablets, carried out according to USP paddle method, and were compared with their commercial counterparts. The results obtained shows that all glipizide liquisolid tablets exhibits higher dissolution rates than those of marketed glipizide tablets. Dissolution rates increases with increasing concentration of liquid vehicles and maximum drug release achieved by formulations containing Polyethylene glycol 400 (PEG 400) as a liquid vehicle. The results of XRD and thermal analysis did not show any changes in crystallinity of drug and interaction between glipizide and excipients during the formulation process.
