Nanoparticles and their Therapeutic Applications in Pharmacy

Nanotechnology is providing solutions several pharmaceutical drug delivery issues. With the emergence of nanotechnology, researchers become more interested in studying the unique properties of nanoscale materials. Nanoparticles are attractive tool in pharmaceutical and biomedical fields. These particulate systems have been used as a physical approach to alter and improve the pharmacokinetic and pharmacodynamic properties of various types of drug/proteins. Nanoparticles have been used in-vivo to protect the drug/proteins molecules in the systemic circulation, targeting of the drug to the chosen sites and to deliver the drug at a controlled and sustained rate to the site of action. Various types polymers have been used in the formulation of nanoparticles for drugs, proteins, and hormone delivery are discussed in this article. It also describes various methods of preparation, advantages, disadvantages and their applications in biomedical fields. It provides an overview of characterization of nanoparticles, storage, and commercially available nanoformulations.
