A comprehensive review on Liposomes: a novel drug delivery system

Abstract

Liposome was derived from two Greek words “Lipos meaning fat and Soma meaning body”. Liposome were spherical shaped vesicles consist of phospholipids and cholesterol. Due to their size hydrophobic and lipophilic character   they are very promising system for drug delivery. This novel drug delivery system aims to target the drug directly to the site of action. Liposomes are very biocompatible and stable and have unique property to entrap both hydrophilic drug and lipophilic drug (amphiphatic nature) to its compartment and lead to   controlled release effect. They are of 0.05- 5.0 micrometer in diameter. Liposomes are used for the treatment of various diseases like tumors or cancer. This article provides an overview of Liposomal Drug Delivery System and various aspects related to liposome that can be studied. Keywords: Liposomes, novel delivery, amphiphatic, controlled release.
