Question

Discuss in detail on Niosomes.

Answer 1

A Niosome is a non-ionic surfactant-based Vesicle (biology and chemistry). Niosomes are formed mostly by non-ionic surfactant and cholesterol incorporation as an excipient.[1] Other excipients can also be used. Niosomes have more penetrating capability than the previous preparations of emulsions.[2] They are structurally similar to liposomes in having a bilayer, however, the materials used to prepare niosomes make them more stable. It can entrap both hydrophilic and lipophilic drugs, either in an aqueous layer or in a vesicular membrane made of lipid material.
