Effect of olive oil on transdermal penetration of flurbiprofen from topical gel as enhancer

The present study was conducted to formulate and evaluate flurbiprofen transdermal gel. a standard calibration curve was constructed to obtain a regression line equation to be used for finding out the concentration of drug in samples. olive oil was used as penetration enhancer and was added in different concentrations to some selected formulations to see its enhancement effect on in vitro drug release profiles. the prepared gels were evaluated for several physico-chemical parameters to justify their suitability for topical use. the in vitro drug release studies were carried out by using franz cell diffusion apparatus across both synthetic membrane and excised albino rabbit skin. in order to investigate the drug release mechanism a kinetic approach was made by employing korsmeyer kinetic model to the in vitro drug release profiles of flurbiprofen. the flurbiprofen topical gels were successfully prepared and could be beneficial for topical use.
