Transdermal drug delivery is an alternative route for systemic drug delivery, which minimizes the absorption and increase the bioavailability. Orally Terbinafine undergoes extensive metabolism and frequent high doses are required to maintain the therapeutic level as a result, dose development toxic effect. The purpose of this research work was to formulation and evaluation of transdermal drug delivery system of Terbinafine using various polymers such as HPMC E25, Eudragit-RS100 and PVP K25 with different proportions by solvent evaporation technique. The Fourier transform infrared study revealed no physical or chemical interactions between Terbinafine and excipients. The prepared formulations were evaluated for different physicochemical characteristics such as thickness, folding endurance, drug content, percentage moisture absorption, and percentage moisture loss. The diffusion studies were performed by using modified Franz diffusion cells. The result of dissolution studies shows that formulation, SA12 showed maximum release of 92.56% in 06 h, whereas SA22 showed minimum release of 45.89% in 06 h. Based on the drug release and physicochemical values obtained the formulation SA 12 is considered as an optimized formulation, which shows higher percentage of drug release.
