The new mathematical model was developed by studying angle of slide using N, N-dimethyl acetamide, non-volatile liquid vehicle and prepared liquisolid tablets, in which the different concentrations of non-volatile liquid adsorbed over carrier and coating material separately. Both DSC and FT-IR study showed better compatibility and stability. The optimized formulation showed higher drug release during in-vitro and in-vivo study against conventional and marketed preparation. The present work concludes that N, N-dimethyl acetamide enhanced the solubility of pioglitazone HCl with higher dissolution rate through liquisolid technique.
