POLYMER: A BOON TO CONTROLLED DRUG DELIVERY SYSTEM
Journal Title: International Research Journal of Pharmacy (IRJP) - Year 2013, Vol 4, Issue 4
Abstract
Polymer plays a vital role in novel drug delivery systems with its longevity and self-transforming quality as excipient in tablet and capsule formulations. Use of polymer is now extended to controlled-release and drug-targeting systems. Polymers are obtained from natural sources as well as chemically synthesised. Polymers obtained from natural resources are used as such and also chemically modified for various applications. Polymers are classified as biodegradable and non biodegradable. The majority of biodegradable polymers used in controlled drug delivery undergo bulk erosion. In the present paper, classification of polymer along with their characteristics is given.
