POLYMERS USED IN FLOATING DRUG DELIVERY SYSTEM: A REVIEW

D. P. Kulkarni and S. S. Saboo*

ABSTRACT

Oral drug delivery system is the most preferred route of administration for drug delivery. In the development of the drug delivery system many components play important role. Polymers are amongst those components which have evolved with the drug delivery system. Polymers are the macromolecule compound containing many monomer units joined to each other by bonds. Polymers used in the drug delivery system are of two types Natural and Synthetic based on their origin. Both types of the polymers have some advantages and disadvantages. This particular article gives information about the different types of natural and synthetic polymer used in the drug delivery system. This article also provide information about the different evolution stages of polymer in medical field. Natural polymers like guar gum, chitosan, xanthum gum, Gellan gum and sodium alginate are mentioned in the article. Synthetic polymer mentioned are HPMC, Eudragit, and Ethylcellulose.

Keywords: Polymers, HPMC, GRT, floating drug delivery system.
