An Overview on Natural Polymers in Novel Drug Delivery System

Abstract

Any pharmaceutical formulation contains two ingredients, one is the active ingredient and other is an excipient. An excipients help in the manufacturing of dosage form and it also improve physicochemical parameters of the dosage form. Polymer plays an important role as excipients in any dosage form. They influence drug release and it should be compatible, nontoxic, stable, economic etc. They are broadly classified as natural polymers and synthetic polymer. They have wide range of application, so selection of polymer is the main step in designing any dosage form. Now a day, due to many problems associated with drug release and side effects manufacturers are inclined towards using natural polymers. Natural polymers are basically polysaccharides, so polymers are biocompatible and without any side effects. This review discusses various natural polymers, their advantages over synthetic polymers and role of natural polymers in designing novel drug delivery system.

Keywords: Polymer, Polysaccharides, Emulsifying agent, Protein, Biocompatible
