Abstract

The present study concerns the development of polymeric films of Ketorolac tromethamine by solvent casting method to explore the possibilities of using kollidon SR as a transdermal drug delivery system. Ketorolac tromethamine was used as a model drug & incorporated in low doses. The films were prepared by using various amounts of Kollidon SR to prolong the drug release with localized action. Some films were also prepared containing certain percent of PEG-6000 along with the drug & polymer. The prepared polymeric films were evaluated for various parameters like weight uniformity, flatness, % elongation, surface pH, uniformity of drug content, in-vitro dissolution studies. The drug-polymer ratio was found to influence the drug release. The rate of drug release decreased with increased polymer concentration. About 10% increased in polymer concentration causes 50% decreased drug release. All the formulation followed Higuchian kinetics & the mechanism of release was diffusion mediated. When PEG-6000 was used as a channeling agent in this formulation drug release was increased accordingly but higher concentration of PEG-6000 results in decreasing release rate of drug because of increasing viscosity of the matrix channels.
