Microemulsions are one of the most excellent candidates as novel drug delivery system because of their long shelf life, better drug solubilization with ease of preparation and administration. Microemulsions are isotropic system, which are difficult to formulate than ordinary emulsions because their formulation is a highly specific process involving impulsive interactions among the constituent molecules. These systems are currently of interest to the pharmaceutical scientist because of their extensive potential to act as drug delivery vehicles by incorporating a extensive range of drug molecules. They suggest the advantage of impulsive formation, ease of manufacturing and scale-up, thermodynamic stability, and enhanced drug solubilization and bioavailability.
