A Brief Review on Emulgels

Topical drug delivery system is good drug delivery system, in which drug directly contact with skin produces its pharmacological effect to targeted site to cure and treat various disorder. Emulgels is an emerging topical drug delivery system that will prove boon to skin care and cosmetology. Emulgels are prepared by the incorporation of the emulsion into the gel with constant stirring at a moderate speed. Emulsions are either available in an oil in water or water in oil type. Incorporation of emulsion into a gel makes it a dual control release system, increasing its stability and provides better drug releases. Due to presence of gel phase which enhances patient compliance. Emulgels contains permeation enhancers to overcome permeation problems and improve transmission of drug into skin. Emulgels are non-greasy, improves bioavailability, patient compliance and stability over than other semi solid dosage forms like lotions, creams, gels, emulsions and ointments. Emulgels is used to treat aches and pains caused by colds, headaches, muscle, aches, backaches, arthritis and other conditions. The prepared emulgels are evaluated by various tests - PH, viscosity, particle size, zeta potential, spread ability, swelling index, drug content, stability study, skin irritation test, Extrudability test, ex vivo permeation test. This review gives knowledge about emulgels including its properties, advantages, formulation components, evaluation tests and applications.
