Transdermal drug delivery is an alternative route for systemic drug delivery which minimizes the absorption and increases the bioavailability. Orally lornoxicam has a short elimination half-life (3-4 hrs.), low oral bioavailability undergoes extensive first pass 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 lornoxicam transdermal patches using various polymers such as HPMC, Eudragit RL 100 and Eudragit RS 100 by solvent evaporation technique for improvement of bioavailability of drug and reducing toxic effects. The prepared formulations were evaluated for different physicochemical characteristics like thickness, folding endurance, drug
