With the GRDDS, the dose shape remains controllably in the stomach after oral administration, so that the medication may be continually delivered to its absorption receptors in the intestinal tract. The medicine is delivering in a controlled and extended way. Gastro-retentive dose in the stomach area may last for another few hours and substantially lengthen the gastric residence period of the medicines. While the bulk density in the system for the supply of floating medicines (FDDS) exceeds the gastric fluids, it remains for an extended duration in the stomach without altering the rate of decomposition. The medication distributes gradually as the system floats on the stomach juice. As a consequence, stomach residency takes longer and plasma concentrations are well monitored. The therapy of peptic ulcer illness might be beneficial for local activity in the upper portion of the intestine, i.e., a longer stomach residency. In addition, medicines rapidly absorbed in the GI tract will increase bioavailability through delayed stomach release. The regulated gastric retention of solid dose forms can also be accomplished by the simultaneous administration of pharmacological agents, or by sedimentation, flotation processes, muco-adhesion, expansion, changed shape systems, by delaying the stomach emptying. Keywords: Gastro-retentive drug delivery system, Floating drug delivery system, Muco-adhesion, Bioavailability.

Current pharmaceutical situation focuses on the preparation of gastro-retentive floating drug delivery system (GRFDDS). This systems has gained noteworthy interest in the past decades. These are the low density systems that float over the gastric contents and remain buoyant in the stomach for a prolonged period of time without affecting the gastric emptying rate. GRFDDS is used to delay the residence time of delivery in stomach. The controlled gastric retention of solid dosage forms may be achieved by the mechanism of mucoadhesion, floatation, sedimentation, expansion, modified shape systems or by the administration of pharmacological agents that delaying gastric emptying. This results in targeting of release of drug at a specific site for the systemic or local effects. GRDDS is used to overcome challenges associated with conventional oral dosage forms and to release the drug at a specific absorption site to improve bioavailability of particular drug substance. Some floating drug delivery systems have shown the capability to accommodate these variations without affecting drug release. This review mainly focuses characterizations and application of gastro-retentive floating drug delivery systems.
