ABSTRACT:
Drug targeting is the ability of a therapeutic agent to act on the site of action which is prior to be desired having little or no interaction with non-target tissue. Niosomes are one of the best carriers for drug targeting. Niosomes are Microscopic lamellar structures and similar to liposomes which can be used as carrier of lipophilic and amphiphilic drugs. The size of niosome is very small (lies in Nano metric scale) than liposome, and have several advantage over liposomes. Niosomes are prepared by admixture of non-ionic surfactant of the alkyl or dialkyl polyglycerol ether class and cholesterol with subsequent hydration in aqueous media. Niosomes can be SUV (Small Unilamellar Vesicles), MLV (Multi lamellar Vesicles) or LUV (Large Unilamellar Vesicles). The method of preparation of niosome is based on liposome technology. The basic process of preparation is same like hydration by aqueous phase of the lipid phase which may be either a pure surfactant or mixture of surfactant or mixture of surfactant with cholesterol. Niosomes are important vehicle for drug delivery and being nonionic which is less toxic and improve the therapeutic index of drug by restricting action to target cells. Niosomes have shown good release profile and thus serve better option for drug delivery system.
