Novel drug delivery system for the vesicular delivery of drug by the niosomes

Non-ionic surfactant vesicles (or niosomes) are now widely studied as alternates to liposomes. An increasing number of nonionic surfactant has been found to form vesicles, capable of entrapping hydrophilic and hydrophobic molecules. Drug delivery system using colloidal particulate carrier such as liposomes or niosomes has distinct advantages over conventional dosage forms because the particles can act as drug containing reservoirs. Modification of the particle composition or surface can adjust the affinity for the target site and/or the drug release rate. Niosomes proved to be a promising drug carrier and has potential to reduce the side effects of drugs and increased therapeutic effectiveness in various diseases. © 2011 Universal Research Publications.
