Natural Based Polysachharides for Conroll Drug Release

Abstract

Considerable research efforts have been directed towards developing safe and efficient Natural based polysaccharide particulate drug delivery systems. The present review outlines the major new findings on the natural based polysaccharides such as Chitosan, Alginate, Pullan,Scleroglucan,Guargum,Gallengum and their characteristics, applications are covered. Chemically modified natural based polysaccharides or its derivatives used in drug delivery research are discussed critically to evaluate the usefulness of these systems in delivering the bioactive molecules. From a literature survey, it is realized that research activities on polysaccharide/nanoparticulate systems containing various drugs for different therapeutic applications and gene therapy have increased at the rapid rate. Hence, the present review is timely.
