Emulgel: A Novel Technique for Transdermal Drug Delivery

Abstract

Topical drug delivery is obtained chiefly for the local dermatological action, but new technologies recently enhanced its systemic effect. They are generally applied for antiseptics, antifungal agents, skin emollients, and protectants. The activity of topical preparation confides in various factors such as drug solubility, lipophilicity, contact time to the skin, and permeability. Typically topical agents like lotions, ointments, creams, gel are associated with drawbacks like stability problems, stickiness, poor permeability, poor absorption, lesser spreading coefficient, irritation, allergic reactions, and difficulty absorbing large molecules. The new concept of Emulgel has been introduced Emulgel. Emulgel systems are currently of attention to pharmaceutical scientists because of their substantial potential to act as drug delivery vehicles by incorporating a broad range of drug molecules. These are either an emulsion of water in oil type or oil in water, gelled by blending it with a gelling agent. Incorporating the emulsion into gel makes it a dual control release system and also increases its stability. The overview gives the ideal properties, formation, and evaluation of emulgels.
