Review On : Bilayer Floating Tablet

The bilayer floating tablet is the key component of the floating drug delivery system (FDDS), which is the main method for extending the gastric residence time in the stomach. In addition to systemic uses, it is more effective for treating gastrointestinal tract local infections like peptic ulcer, gastritis, Zollinger-Ellison syndrome, indigestion, and other similar local infections. For drugs that are acid labile and have a brief half-life, FDDS offers protection. It also extends the residence time of drugs, decreases drug waste, and enhances bioavailability. For the development of FDDS, many different technologies are now being used. Bilayer floating tablet formulations incorporating novel drug delivery systems have also expanded the function of FDDS
