Main Article Content
features of microemulsions are thermodynamically stable, clear, colloidal dispersion of water and oil that are stabilized by surfactant and cosurfactant. Microemulsion typically has a droplet diameter of approximately 100 nm or less. Microemulsions
have numerous applications in pharmaceutics and many other industries. In the present review we shall discuss about the various aspects of microemulsion with respect to the field of non steroidal anti inflammatory drug, along with its preparation,evaluation and research work carried out in microemulsion.
