CONCLUSION AND FUTURE SCOPE Drug incorporation in the niosomes to target the niosomes to the specific site is a promising drug delivery model. They present a structure similar to liposome and hence they can represent alternative vesicular systems with respect to liposomes, due to the niosome ability to encapsulate different type of drugs within their multienvironmental structure. Niosomes are considered
to be better candidates for drug delivery as compared to liposomes due to various factors like cost, stability etc. Niosomes are promising vehicles at least for lipophilic drugs. These advantages over the liposomes make it a better targetting agent. Ophthalmic, topical, parentral and various other routes are used for targetting the drug to the site of action for better efficacy.
