Efficient drug targeting to diseases by circumventing all the shortcomings of conventional drug delivery systems can be achieved by the significant approach of advances in nanotechnology. Nanotechnology will affect our lives tremendously over the next decade in very different fields, including medicine and pharmaceutical Sciences. Most of the available drugs now are lipophilic in nature and this stands as challenging aspect faced for scientists to formulate and deliver for better efficacy, so nanoparticles, nanosuspension, nanocapsules are used now days to deliver these drugs with greater bioavailability and also have been adopted to improve the solubility of poorly soluble drugs. The use of nanoparticles is an universal formulation approach to increase the therapeutic performance of drugs in any route of administration. This review article describes the preparation methods, physicochemical properties, applications, clinical advantages, and recants developments of nanoparticles and their potential in drug delivery systems.
