Abstract

A NEW FUTURE APPROACH ON NOVEL DRUG DELIVERY SYSTEM THROUGH EMULGEL

R. B. Saudagar* and M. V. Dukare

ABSTRACT

In comparison among the other groups of semisolid preparations, the use of gels has been emerged both in cosmetics and in pharmaceutical preparations because of its unique array of features. Despite of providing several benefits the category gel faces limitations in delivering hydrophobic drug molecules via skin. So in order to cover up this lacking a recent emulsion based approach is being used so that even a hydrophobic therapeutic moiety can enjoy the unique properties of gels. The use of gels and emulsions as combined dosage form results into formation of emulgel showing dual release. With this approach the use of polymers with enhanced effect in release pattern has been emerged providing sustained and controlled release. The topical drug delivery system is generally used in the system of drug administration fails or in local skin infection like fungal infection. The presence of a gelling agent in the water phase converts a classical emulsion into an emulgel. Then emulgels can be used as better topical drug delivery systems over present systems. The use of emulgels can be expanded in analgesics, anti-inflammatory, anti-fungal, anti-acne drugs and various cosmetic formulations.
