ABSTRACT

The objective of the present study was to prepare a topical film-forming gel of Ketoprofen for the treatment of rheumatic diseases, using a patient-friendly drug delivery approach. The localized treatment of diseases of our body tissues requires that the pharmaceutical active to be maintained at the site of treatment for an effective period of time. Sweat, clothing, movements and getting washed away easily on contact with water are some of the problems that have limited the effectiveness and residence time of conventional topical formulations mainly used for treatment of arthritis. This necessitates longer treatment duration. The present work aims at designing a dosage form of Ketoprofen referred to as a ‘film-forming gel’ which on application forms a thin, transparent film on skin surface Ketoprofen film-forming gels were prepared using hydroxyl propyl methyl cellulose and polyvinyl pyrrolidone polymeric blend in varied concentrations, polyethylene glycol 400 (PEG 400) as plasticizer and ethanol as solvent. Optimization was done by central composite method taking spreadability and drying time as the variables. The prepared film-forming gels and films formed after solvent evaporation were evaluated and the influence of the concentration and ratio of polymeric blends used were investigated. The concentrations of both the polymers were optimized by Central composite design to obtain optimum spreadability and drying time. The formulation F3 with a maximum spreadability and minimum drying time was selected as the optimized formulation.

Keywords: Film-forming gel, Ketoprofen, Hydroxy propyl methyl cellulose and polyvinyl pyrrolidone.
