Polymers Used In Floating Drugs Delivery System-A Review

The most popular method of administering drugs is through an oral route of administration. Many parts are crucial in the formulation of the drug delivery system. Polymers are among the elements of macromolecules that have changed along with the drug delivery mechanism, polymers are chains of monomers. Based on their origin, the two main types of polymers are employed in drug delivery systems that are synthetic and natural. Each variety of polymers possesses certain benefits and drawbacks. This article lists a number of natural polymers, including sodium alginate, guar gum, chitosan, xanthan gum, and Gellan gum. The most often used synthetic polymers are ethylcellulose, HPMC, eudragit, and carbapol. For those drugs that are mostly absorbed in the upper parts of the gastrointestinal (GI) tract, the gastro retentative drug delivery system (GRDDS) or floating drug delivery system (FDDS) become an extra benefit. Due to their lower density than stomach content, floating drug delivery systems have emerged as an important and cutting-edge technique during the past few decades. The goal of preparing this review article is to concentrate on the uses of synthetic and natural polymers floating drugs delivery system.
