Prachi Patel*, Rima Patel and Anil Raval

ABSTRACT

Emulgels are topical dosage form in which emulsions are gelled by mixing with gelling agent. Incorporation of emulsion into gel increases stability of emulsion and provides controlled release system. Emulgels have emerged as a promising drug delivery system for the delivery of hydrophobic drugs. For the treatment of local as well as systemic skin disorders, topical drug delivery systems have been used for centuries offering the advantage of delivering the drug directly to the site of action and also delivering the drug for extended period of time at the affected area. They are emulsions of either oil-in-water or water in oil type. Thus emulgels have major advantages on novel vesicular system as well as on conventional systems in various aspects. They are referred for topical use due to their favorable properties such as being greaseless, non-staining, thixotropic, emollient, easily removable, water soluble, bio-friendly, long shelf-life, transparent and pleasant appearance. e. Emulgels are used as better topical drug delivery systems over other systems because of many properties. The use of emulgels can be found in analgesics, anti-inflammatory, anti-fungal, anti-acne drugs and various cosmetic formulations.
