FORMULATION AND EVALUATION OF CLOPIDOGREL BISULFATE TRANSDERMAL PATCHES

Transdermal drug delivery is an alternative route for systemic drug delivery which minimizes the absorption and increases the bioavailability. The main objective of the present work was to develop a suitable matrix type transdermal drug delivery system of Clopidogrel bisulphate using different polymers HPMC E15, Eudragit L100 and to compare the drug release through physical method and chemical method. Matrix type transdermal patches containing Clopidogrel Bisulfate were prepared by solvent evaporation technique. The prepared transdermal patches were evaluated for Thickness, folding endurance, tensile strength and in vitro studies. The prepared transdermal drug delivery system of Clopidogrel bisulphate using different polymers such as HPMC E15 and Eudragit L 100 had shown good promising results for all the evaluated parameters. Based on the In-vitro drug release, drug content and folding endurance results formulation F4 was concluded as an optimized formulation which shows its higher percentage of drug release.
