Abstract

The review mainly shows the role of polymer used in drug delivery of therapeutic agent and also application of polymers in various drug delivery. Polymers are substances whose molecules have high molar masses& pressed together by a large number of repeating units. Polymers has been used as a main aid to control the drug release from the formulations. On the basis of various conditions or processes polymers are classified as a addition polymer, condensation polymer, natural polymer, synthetic polymer, chain growth polymerization, step growth polymerization, biodegradable polymer, non biodegradable polymer etc. Role of polymers in various dosage form like immediate release, modified release, extended release and gastroretentitvedosage form. In Pharmaceutical Industry polymers used as binders, film coating to mask unpleasant taste, flow controlling agent, to enhance drug stability, to modify drug release characteristics. Various application of polymers in tableting, capsules, disperse system, gels, patches, ocuserts, colon targeted, mucoadhesive, sustained, floating, tissue targeting, nanoparticles, drug conjugates, and swelling controlled system etc.
