The Pharmaceutical Polymer’s; A Current Status In Drug Delivery: A Comprehensive Review

Abstract

Polymers are a large class of materials consisting of many small molecules. Polymers are the backbone of a pharmaceutical drug delivery system as they control the release of the drug from the device. The main role of polymer is to protect drug from physiological environment and prolong release of drug to improve its stability. The drug is release from polymer by diffusion, degradation and swelling. Nowadays, due to many problems associated with drug release and side effects of synthetic polymers, manufacturers are inclined towards using natural polymers. Natural polymers being poly saccharides are biocompatible and without any side effects. The main highlights of this review article to discuss the basics of polymers, polymerization chain with their ideal characterization including their classification. The lastly discussed points to utilization of polymer role in diverse drug delivery and their various pharmaceutical application including future directions and challenges as well widely in polymer’s application
