SOLUBILITY AND DISSOLUTION ENHANCEMENT OF PIOGLITAZONE USING SOLID DISPERSION TECHNIQUE

Objective: To design the study to improve the solubility and hence enhance the dissolution of hydrophobic drug Pioglitazone in order to increase its bioavailability.Methods: Solid dispersion of Pioglitazone using carriers Poloxomer 188 and HPβCD was formulated in different ratios by microwave induced fusion method. In particular, the Microwave technology has been considered in order to prepare an enhanced release dosage form for poorly water soluble drug Pioglitazone. Statistical Analysis: Their physicochemical characteristics and solubility were compared to the corresponding dispersions and marketed drug. Drug and polymer were further characterized by FTIR.Results: The results of FTIR revealed that no chemical interaction between the drug and the polymer exist.Conclusion: All the formulations showed a marked increase in drug release with the increase in the concentration of Poloxomer 188 and HPβCD.Â
