Nanoparticulate Drug Delivery Systems: An update

The paper is aimed to provide a comprehensive review on nanoparticles, methods of preparation, applications in drug delivery. In recent years, there has been an exponential interest within the development of novel drug delivery systems using nanoparticles. Nanoparticles offers significant advantages over the conventional drug delivery in terms of high stability, high specificity, high drug carrying capacity, ability for controlled release, possibility to use in several route of administration and therefore the capability to deliver both hydrophilic and hydrophobic drug molecules. This review focuses on classification, methods of preparation, characterization, application, advantages of nanoparticles and health perspectives.
