Nanocrystal Drug Delivery System:A Review

Nanotechnology is the science in which the particle having the size below 1000nm.Theimportance of nanotechnology in drug delivery is in the concept and ability to manipulate molecules and supramolecular structures for producing devices with programmed functions. One of the major application areas of nanotechnology in pharmacy is nanoparticular drug delivery system. Preparation of nanocrystals to improve the solubility of poorly water- soluble drug for oral delivery is also one of the important applications. Drug nanocrystals are crystals with a size in the nanometre nanoparticle with a crystalline character .The use of drug Nanocrystals is an universal formulation approach to increase the therapeutic performance of these drugs in any rout of administration.
