Nanobased Drug Delivery System: A Review

Nanoscience and nanotechnology are the emerging area in recent years, particularly in drug discovery and development process. Nanotechnology has wide variety of applications in pharmaceutical sciences. The major applications of nanotechnology are development of dosage forms that may have better efficacy than conventional dosage forms. Nanocrystals are used to improve the pharmacokinetic properties such as solubility and permeability. Nanoparticles are used to target the drug at specific site of the body or tissue. Various technologies which are used to fabricate the nano based drug delivery systems are reviewed.
