AN OVERVIEWON NIOSOMESAS DRUG DELIVERY

Over the years, researchers have attempted to improve the potency of medicament utilization for the treatment of a variety of diseases. Drug targeting is a phenomenon in which a drug is distributed in the body in such a way that it interacts with the target tissue at a cellular or sub-cellular level to achieve a desired therapeutic response at the desired site while avoiding unwanted interactions at other sites. This can be accomplished using modern drug delivery system targeting methods such as niosomes. Niosomes are a novel drug delivery system that encapsulates the medication in a vesicle. The vesicle is made up of a non-ionic surfactant bilayer. The particle size of the niosome must be in the range of 10 nm -100 nm. Niosomes are preferred over liposomes because they are more stable and less expensive. Niosomes enhance the pharmacological action of drug molecules by delaying the drug\'s clearance from circulation, protecting the drug from the biological environment, and limiting the effects to the target cells. It has applications in cancer treatment, as a carrier in hemoglobin, delivery of peptide drugs via the oral route, treatment of leishmaniasis, ophthalmic delivery, and as a carrier in dermal drug delivery. This review article focuses on the vesicular system\'s composition, benefits, types of niosomes, methods of preparation, characterization, and application.
