Different Techniques for Preparation of Nanosuspension with Reference to its Characterisation and various Applications-A Review

Nanosuspensions it is a colloidal dispersions of nanosized drug particles stabilized by various surfactants. They can define as a biphasic system consisting of pure drug particles dispersed in an aqueous vehicle in which the diameter of the suspended particle is less than 1μm in size. Nanosuspension are the most of the rapidly developing field of nanotechnology with various applications in drug delivery, medical and research as that of other medical sciences and develop new therapeutics. Now day a new generation of Nanosuspension (NS) consisting of a mixture of two phases in that one it is a solid and another is liquid. Nanosuspension technology solved the problem of drugs which are poorly aqueous soluble and less bioavailability. Stability and bioavailability of the drugs can be improved by the Nanosuspension technology, also the Nanosuspension improves drug loading and firmly incorporates the drug during storage. The present review gives highlight on the different techniques for preparation and characterization of Nanosuspension as Particle Size, Zeta Potential, Entrapment Efficiency, Stability Study and the importance of NLC in pharmaceutical applications.
