In present study, different transdermal patches of Pioglitazone hydrochloride were prepared using different polymers and evaluated on many parameters. Locally fabricated Franz diffusion cell was used for the in-vitrorelease study. Result revealed that there is a direct relationship with weight of the patch and drug content. The thickness lies in the range of 0.027 to 0.038 mm. Average thickness was almost uniform within same formulation, a small variation in thickness was observed with different formulations. The weight of patches lies in the range of 43.31 to 46.3 mg. The percentage of the drug content lies in the range of 96.87 to 99.28. Content uniformity studies proved that the amount of Pioglitazone hydrochloride in each patch of 2.009 cm2 was found to be fairly uniform. Percent moisture absorption was found to be in the range of 4.388 to 5.465, largest in formulations of batch code T3 and least in the batch code T2.The prepared transdermal drug delivery system of Pioglitazone hydrochloride using different polymers such as HPMC, EC, Chitosan and PVP had shown good promising results for all the evaluated parameters. However, for the in-vitro drug release and drug content result, formulation T4 was shown to be the optimized formulation, as higher percentage of drug release was obtained.
