AbstractKetoprofen is one of the very potent and safe non steroidal anti-inflammatory drugs (NSAIDs) that belong to the propionic acid derivatives group. The aim of this study was to prepare spray film of ketoprofen and evaluate its properties as pH, viscosity, volume of solution delivered per each actuation, spray angle, evaporation time, content uniformity, and in vitro drug release. Different types of film forming polymer were investigated. The best formula containing mixture of 0.05% w/w poloxamer 407 and 0.05% w/w carbopol 940 was found to have pH, content uniformity, viscosity, drying time, volume per each actuation, and spray angle of 5.2, 100.6%, 1.5 mpse, 91sec., 0.09 ml, and 79.90 respectively. Drug release of the selected film was found to be 49.7% at 20 hrs with kinetic release of Higuchi model (R 2 of 0.9). Based on abstained results, it was concluded that ketoprofen can be prepared as dermal spray film using a mixture of 0.05% w/w for both poloxamer 407 and carbopol 940 as film forming polymer.
