Nanosuspension in Drug Delivery A Review
Nanotechnology is the science that deals with the process that occurs at molecular level and of nano length scale size. Nano refers to the particle size range of 1 1000 nm. Nanosuspensions are coming under nanotechnology. A pharmaceutical Nanosuspension is defined as very finely colloid, biphasic, dispersed solid drug particles in an aqueous vehicle, size below 1 mm stabilized by surfactants and polymers prepared by suitable methods for drug delivery applications. It provides efficient delivery of hydrophobic drugs and increases the bioavailability. Nanosuspension is an attractive and promising technology to improve poor solubility and bioavailability of the drugs. This review article describes the methods of preparation, and applications of nanosuspensions in the field of pharmaceutical sciences.
