The concept of research subscribed in this article is directed towards the development of some NDDS for the treatment of various life threatening diseases and disorders. The nanosuspension can be proved as a gift as the poorly water soluble drugs can be easily formulated into nanosuspension. One of the critical problems associated with poorly soluble drugs is too low bioavailability. There are number of formulation approaches to resolve the problems of low solubility and low bioavailability. Nanosuspension not only solves the problems of poor solubility and bioavailability but also alters the pharmacokinetics of drug and thus improves drug safety and efficacy. Nanosuspensions are sub-micron colloidal dispersions of nanosized drug particles stabilized by surfactants.
