Recent Perspectives of Chitosan: A Review

Considerable research efforts have been directed towards mounting safe and competent chitosan-based particulate drug delivery systems. Chitosan is an abundant, naturally occurring polymer with versatile functionalities. Its non allergenicity, biocompatibility, biodegradability and cationic surface charges in acidic medium allow it to have applications in a variety of conventional and pharmaceutical areas. Over the years, numerous strategies for Chitosan and its derivatives have been explored. As evidenced by the literature, it was seen that the viability and prospect of chitosan-mediated drug delivery could be optimistic. The present review outlines the major new findings on the pharmaceutical applications of chitosan-based drug delivery systems published over the past decade and also reviews the recent reports on the preparation, properties and biomedical applications of chitin and Chitosan.
