SIGNIFICANCE OF NANOCRYSTALS IN DRUG DELIVERY

Journal Name:

Publication Year:

Abstract (2. Language): 
For the past few decades, there has been a considerable research interest in the area of drug delivery by using particulate delivery systems as carriers for small and large molecules. Significance of nanocrystal drugs is mentio this review. Nanocrystals are aggregates anywhere from a few hundred to tens of thousands of atoms that combine into a crystalline form of matter known as a "cluster". They are used as a physical approach to alter and improve the pharmacokinetic and pharmacodynamic properties of various types of drug molecules. They have been used in vivo to protect the drug entity in the systemic circulation. The method of preprations of nanocrystal is down, top down and bottom up, spray drying and so new techniques. These approaches are paving the way to the development of nanosized objects which are able to perform multiple technological tasks. There are several important advantages of nanocrystal formulations such as, enhanced oral bioavailability, improved dose proportionality, reduced food effects, suitability for administration by all routes and possibility of sterile filtration due to decreased particle size range. selection depends upon the sites and to deliver the drug at a controlled and sustained rate to the site of action. Here, we review various aspects of nanocrystals formulation, characterization, effect of their characteristics and their pharmaceutical applications in delivery of drug molecules and therapeutic genes.
