Glycerosomes: A Novel Vesicular Drug Delivery System

Abstract

Glycerosomes are novel vesicular drug delivery systems used both for topical as well as systemic drug delivery. These noninvasive carriers can penetrate into the deeper layer of skin to such extent a free drug would not penetrate. Glycerosomes are composed of phospholipids, water and high concentration of glycerol (from 20 to 40%), which are harmless and fully acceptable ingredients for topical preparations. High concentration of glycerol gives positive contributes to the penetration of drug by increasing flexibility of vesicles; italso enhances the stability of vesicles.They have capability to encapsulate both lipophilic and hydrophilicdrugs and protect them from degradation. Now a days glycerosomal carrier are the most interesting area of work for researchers. This review article summarizes the structure, advantages, composition, methods of preparations, characterization and applications of glycerosomes.
