Objectives: The purpose of this study was to develop a transdermal patch containing the drug nicorandil with different ratios of Eudragit RL 100 polymeric by solvent casting method. Methods: The prepared patches were evaluated for physicochemical characterization, thickness uniformity, mass uniformity, drug content uniformity, folding endurance, moisture loss, FTIR, SEM, in vitro release, ex vivo permeation, and stability studies. Findings: The results of the studies suggest that formulated transdermal patches with good physical properties and drug content were obtained by the solvent casting method. Surface morphological studies indicated uniform distribution of drugs in the polymeric patch formulation. The in vitro diffusion study suggested that drug release was controlled by all six formulations in comparison with the pure drug. The cumulative release of the drug in phosphate buffer pH 6.8 from formulations (F1-F6) ranged between 89.55±0.62- 78.52±0.63% in a 12-hour study. Ex vivo results showed a good correlation with the in vitro study results. About 89.55±0.62% of the drug from (F4=drug: polymer 1:4) permeated through the rat abdominal skin sample over a period of 12 h. Novelty: Transdermal patches could be a good alternative for controlled drug therapy with nicorandil.
