Nanosuspensions: A Novel Drug Delivery Approach

Abstract

Nanosuspen sion is a sub - micron colloidal dispersion of pure particles of drug stabilized by surfactants. N anosuspensions can be produced such that nanocrystalsappear in final products. Drug N anosuspensions can be used as intermediateproduct. Formulations of Nanosusp ensions are most suitable for drugs with high log P value. O f the various methods like bottom up, precipitation and top down technologies, top down is the most preferred one. Particle size, size distribution and crystalline state are some of the important parameters to be considered while formulation of
