Excellency of natural polymer in drug delivery system: A Review

Abstract

The purpose of writing this review on natural polymer based drug delivery system (NPBDDS) was to compile the recent literature with special focus on the principal mechanism involved coating technology based on natural polymer to achieve therapeutic goal for prolongation of drug release to the desire site of action. It is well known that the growth of human society was influenced by the expansion of man-made polymers. The recent developments of novel drug delivery technology using synthetic polymers including the physicochemical properties and formulation variables affecting drug release from its dosage form and for that it is essential approaches to design NPBDDS. The natural polymers are presented from their molecular structure point of view along with main fields of applications through advance in drug delivery system (ADDS). This review also summarizes the in vitro techniques, in vivo studies to evaluate the performance and application of NPBNDDS and applications of these systems. These systems are useful to several problems encountered during the development of a pharmaceutical dosage form.

Keywords: Natural polymer, NPBDDS, synthetic polymers, ADDS, in vitro and in vivo
