The present study was undertaken to develop a suitable transdermal matrix patch of ketorolac tromethamine with different proportions of polyvinyl pyrrolidone (PVP) and ethyl cellulose (EC) using a D-optimal mixture design. The prepared transdermal patches were subjected to different physicochemical evaluation. The surface topography of the patches was examined by scanning electron microscopy (SEM). The drug-polymer interaction studies were performed using Fourier transform infrared spectroscopic (FTIR) technique. A correlation between in-vitro drug-release and in-vitro skin permeation was established and the criterion of desirability was employed to optimize the formulation. The results of the physicochemical characterization and in-vitro permeation of the prepared patches were promising to formulate transdermal patches with PVP/EC combinations.
