Films comprising of ethyl cellulose and polyvinyl pyrrolidone (PVP), were investigated for their potential transdermal use. Placebo films were initially evaluated for their mechanical and physical properties. Single films and laminates (double layered films) cast on a backing membrane of polyvinyl alcohol and containing salicylic acid were evaluated for 'in vitro' and 'in vivo' drug release. The results indicate that the formulation studied appears promising.
