Emulgel: A Novel Approach For Topical Drug Delivery System

Abstract

Topical drug delivery has been used from time for the treatment of local skin disorders. Medications applied to the skin for their local action include antiseptics, antifungal agents, skin emollients, and protectants. When gel and emulsion are used in combined form the dosage form are termed as emulgel. Emulgels have appeared as one of the most advanced topical delivery system as it has dual release control system i.e. gel and emulsion. Despite of many advantages of gels, a major limitation is in the difficulty in delivery of hydrophobic medications. So to overcome this limitation an emulsion based approach is being used so that even a hydrophobic therapeutic moiety can be effectively incorporated and delivered through gels.
