Hydrophobic Drug

When gels and emulsions are used in combined form the dosage form are referred as emulgel. Also there has been incredible interest for the utilization of novel polymers and drug molecules. A one of the feature of topical drug delivery is the immediate availability of the skin as  target organ for diagnosis and treatment. Among the different group of semisolid planning, the utilization of gel has extended both in cosmetics and in the pharmaceuticals. Although Gel has many advantages, there is many limitation in delivery of hydrophobic drugs, so to overcome this limitation an emulsion base novel approach is being most used. That is emugel system used so that even a hydrophobic moiety can enjoy the unique properties of gels and having characteristics of dual control release i.e. emulsion as well as gel. The formulation is prepared by various polymer which behave as an emulsifer and thickening agent because of gelling capacity of these compounds give rise to stable emulsions and creams by diminishing surface and interfacial pressure while in the meantime expanding the thickness of the aqueous phase. In order to understand the potential of emulgel as delivery vehicles, this review gives an overview of the ideal properties, formation, and characterization of emulgels. So this can be use as analgesics and antifungal drugs, as superior topical drug delivery systems over present conventional systems available in market.
