ABSTRACT

Pharmaceutical Polymers are the heart of Pharmaceutical formulations either in conventional and novel drug delivery system. The drug release is sustaining, extending, modifying, controlling and targeting based on the use of polymer in different dosage forms and drug delivery system. A proper selection of surface and bulk properties can help in the designing of polymers for various applications in pharmacy. These are widely used as pharmaceutical aids (Binder, suspending agent, emulsifying agent, coating agent, adjuvant etc), packaging materials and medical devices both in conventional and controlled drug delivery system. In this article briefly review Pharmaceutical polymers and their classification, properties, mechanism of drug release and applications of polymers drug delivery system.

Keywords: Polymers, Pharmaceutical aid, Conventional Dosage forms, Controlled drug delivery system, Packaging materials, Medical devices.
