  • Abstract

    During the last two decades, many modern technologies have been established in the pharmaceutical research and development area. The automation of the drug discovery process by technologies such as high-throughput screening, combinatorial chemistry, and computer- aided drug design is leading to a vast number of drug candidates possessing a very good efficacy. Unfortunately, many of these drug candidates are exhibiting poor aqueous solubility. The use of drug nanosuspension is an universal formulation approach to increase the therapeutic performance of these drugs in any route of administration. A nanosuspension is a submicron colloidal dispersion of drug particles which are stabilized by surfactants. Nanosuspension is defined as very finely dispersed solid drug particles in an aqueous vehicle for either oral and topical use or parenteral and pulmonary administration. The particle size distribution of the solid particles in nanosuspensions is usually less than one micron with an average particle size ranging between 200 and 600 nm. Nanosuspension consists of the pure poorly water-soluble drug without any matrix material suspended in dispersion.This review article describes the physicochemical properties of drug nanosuspension, preparation methods and; its potential clinical advantages.
