Niosomes: A New Approach to Targeted Drug Delivery

Targeted drug delivery, sometimes called smart drug delivery, is a method of delivering medication to a patient in a manner that increases the concentration of the medication in some parts of the body relative to others. The goal of a targeted drug deliverysystem is to prolong, localize, target and have a protected drug interaction with the diseased tissue. A niosome is a non-ionic surfactant-based liposome. They are structurally similar to liposomes in having a bilayer, however, the materials used to prepare niosomes make them more stable and thus niosomes offer many more advantages over liposomes. Various type of drug deliveries can be possible using niosomes like targeting, ophthalmic, topical, parentral etc.
