Abstract

Gastro retardation is attractive approach to enhance bioavailability of narrow absorption window drugs. Drug retardation in stomach is more beneficial for certain gastro intestinal disorders like gastro esophageal reflex disease, ulcer and other gastro intestinal conditions. Gastric site retardation is one of the challenging technique, however various techniques are applied to keep the drug and achieve the enhancement of bioavailability. To achieve gastro retentive commonly two approaches are considered, they are floating drug delivery system and non-floating gastro retentive drug delivery system. The floating drug made-up by low density polymers, this approach was not fit many of the drug molecule and floating drug has some limitations like sufficient level fluids in stomach and not to be dosed just before going to bed. In this review describe the various high density (sinking) system (non-floating) drug delivery systems like super porous hydrogels, expanding system, bio/mucoadhesives system, and magnetic system and mechanism, desirable drug characters, advantages and disadvantages.

Keyword: Bioavailability, gastro retentive, magnetic system, mucoadhesive, non-floating and sinking system.
