Abstract

Transdermal patch is a drug delivery device in which the drugs are incorporated and is design in such a way that it releases the drug in sustained and at predetermined rate to deliver the drug through the skin to the systemic circulation painlessly. The aim of this research study was to formulate a controlled and sustained release transdermal matrix type patch of Methimazole. The matrix patch was prepared by solvent casting method using a various polymer in different concentration, HPMC (hydrophilic), Eudragit RL100 and Ethyl cellulose (hydrophobic) polymer. Total 9 prototype formulation were prepared and it was subjected for various evaluation test; weight uniformity, Folding endurance, thickness, Drug content, percent moisture content, percent Moisture uptake and In-vitro drug release study using Franz diffusion cell. The in-vitro CDR% data was fit into kinetics model to see the release kinetics from the patches. The Formulation F5 was choosen as a best formulation according to in-vitro drug release study. The in-vitro release was found 81.12% in 12 hours, it followed zero order kinetics. The nature of polymer and concentration ratio of polymers plays a crucial role for obtaining a good transdermal patch design; therefore optimisation is very important step to formulate a desired TDDS. Therefore the result of the study encourages a further study and is hopeful that the present study would contribute to the recent pharmaceutical research for formulation development.
