Polymer plays a vital role in novel drug delivery system due to its self transforming quality as excipients in formulations. The collaboration of polymeric science with the pharmaceutical science led to the innovation in design and development of novel drug delivery system. Use of polymer is now extended to controlled release and drug targeting systems. Polymers are obtained from natural sources as well as chemically synthesized. They are classified as biodegradable and non biodegradable. Polymers are the backbone of a pharmaceutical drug delivery system as they control the release of a drug from the device. Biodegradable polymers is more acceptable in use as they can be degraded to non toxic monomers and a constant rate of drug release can be achieved from a biodegradable polymer control release device. Natural polymers can be used as a means of achieving pre determines the rates of drug delivery and their physico-chemical characteristics with the ease of availability while a platform to use it as a polymer or drug delivery systems. These improvements contribute to make medical treatment more efficient and prove minimize side effects and other types inconveniences for patients. The main role of polymer is to protect drug from physiological environment and prolonged release of drug to improve its stability.
