Abstract: 
Niosomes represent a promising targeted drug delivery system for hydrophilic and lipophilic drugs. They present a structure similar to liposome and hence they can be an alternative vesicular system with respect to liposomes. Due to the niosome ability to encapsulate different type of drugs within their multi environmental structure they can be exploited for various treatments of various diseases. Niosomes can be a better drug delivery system as compared to liposomes due to various factors like cost, stability. Various routes of drug delivery and drug targeting can be achieved using niosomes.

Keywords: Niosomes, Liposome, Targeting, Ophthalmic, Topical, Parentral.
