Hypertension is a major disease caused by mental stress and work tension. To duplicate the benefits of intravenous drug infusion without its potential hazards, the novel drug delivery system has brought renaissance into the pharmaceutical industry for controlled drug delivery.Transdermal drug delivery systems are also known as patches, containing dispersed or dissolved drug with plasticizers, polymers etc., are intended to deliver a therapeutically effective amount of drug across the skin. In this investigation it was planned to formulate transdermal formulations containing Valsartan (hydrophobic) using two natural gums viz.., Xanthan gum and Almond gum as a reservoir gels planned to characterize the candidate drugs for physico-chemical properties. Membrane-moderated TTS was prepared with rate controlling Eudragit RL 100 polymer, with reservoir gels, and provided with a backing laminate. The films was characterized by WVT studies and SEM photomicrographs. Further, in vitro permeation of the candidate drug was conducted in keshary-chien diffusion cells across depilated abdominal skin of male Swiss albino rat. The data was corrected with Hayton-chien equation, to remove any sample induced bias. Also the data was subjected to regression analysis and ANOVA. A value of p<0.05 shall be considered statistically significant. Various permeation parameters like, flux, diffusivity, and permeability coefficient was determined. Stability of the TTS of Valsartan also studied at 40 ºC / 75 %RH Keywords: Valsartan, Xanthan gum, Almond gum, Eudragit RL 100, Transdermal Systems
