Online published on 15 May, 2014. Abstract Trandolapril is an antihypertensive agent which undergoes extensive first pass metabolism making it a possible candidate for transdermal delivery. Patches were prepared using hydroxypropylmethylcellulose, eudragit RL 100, gantrez and carbopol. The results of FTIR and DSC revealed no interaction between drug and polymers. The loss of moisture and uptake of moisture were within the limits. The formulations showed an extended release of the drug upto period of 24 hours during in vitro permeation studies and showed non-Fickian drug release. Stability of the optimized formulation was investigated as per ICH guidelines and was found to be stable with respect to drug content and in vitro permeation.
