The aim of present study,  To formulate and characterized  proniosome contain flurbiprofen in a gel formulation for the treatment of rheumatoid arthritis and enhanced skin targeted effect, sustained & prolonged drug release, enhanced skin bioavailability by using different type of non ionic surfactant & cholesterol. The batches were designed using Box Behnken Design and prepared by coacervation phase separation method. Optimized formulation (PNGopt) showed drug entrapment efficiency of 74.46% and particle size 215nm. In-vitro drug release from PNGopt was found to be 84.15 in 24 hrs. The In-vitro drug release was best explained by zero order kinetics as the plot showed highest linearity and release was governed by Quasi Fickian diffusion.
