ABSTRACT

Topical drug delivery system can be defined as the application of the formulation onto the skin directly to elicit its pharmacological actions to treat skin diseases. The Major disadvantage of gel is the delivery of hydrophobic drugs, this can be overcome by the novel technique Emulgel. It is a combination of gel and emulsion that forms a dosage form referred to as Emulgel. Emulgel is one of the recent technologies in Novel Drug Delivery System and it also have characteristics of both drug delivery systems i.e., both emulsion as well as gel. The Emulgel is utilized in treating skin infections like fungal infections, acne, psoriasis. The union of hydrophilic cornified cells in lipophilic intercellular material provides a barrier to both hydrophilic and lipophilic layers. Polymers have been used in the manufacturing of emulgel which functions as emulsifiers and thickeners. These Emulgels are having major advantage on Novel Vesicular systems as well as Conventional systems. The use of Emulgels can be extended in Analgesics and Antifungal drugs.
