Liposome- as drug carriers

Abstract

Liposomes are artificially prepared vesicles made of lipid bilayer. Liposomes can be filled with drugs, and used to deliver drugs for cancer and other diseases. Amongst the various carrier, few drug carrier reached the stages of clinical trails where phospholipid vesicles (liposome) show strong potential for effective drug delivery to the site of action. Liposomes can be composed of naturally-derived phospholipids with mixed lipid chains or other surfactants. Liposome have covered predominantly medical, albeit some non-medical areas like bioreactor, catalysts, cosmetics and ecology. However,their predominance in drug delivery and targeting has enabled them to be used as therapeutics tool in fields like tumour targeting, gene and antisense therapy etc.
