Proniosomes as drug carriers.

Approaches to stabilize niosomal drug delivery system without affecting its properties of merits have resulted in the development of the promising drug carrier, proniosomes. Proniosomes is dry formulation using suitable carrier coated with non ionic surfactants and can be converted into niosomes immediately before use by hydration. These proniosome-derived niosomes are as good as or even better than conventional niosomes. The focus of this review is to bring out different aspects related to proniosomes preparation, characterization, entrapment efficiency, in vitro drug release, applications and merits.
