Niosomes a novel trend in drug delivery in which medication is encapsulated in a vesicle and the vesicle made up of bilayer of non-ionic surface active agents and then it is named as niosomes. However niosomes are structurally similar to liposomes in having a bilayer, and the materials used to prepare niosomes make them more stable. After preparing the dispersion of niosomes unentrapped drug is separated by gel filtration or centrifugation. A method of invitro release rate study includes the use of dialysis tubing. niosomes are either unilamellar or multilamellar vesicles formed from synthetic non-ionic surfactants. Niosomal drug delivery applicable to many pharmacological agents for their action through various diseases. Hence niosomes have more penetrating capability than the previous preparations of emulsions.
