A comprehensive review on floating drug delivery system

The category of gastroretentive drug delivery systems (GRDDS) includes floating drug delivery systems (FDDS). These dose formulations are intended to extend the duration of the stomach's residence period by a sustained release technique. Drugs which are harder to dissolve in high pH environments have improved bioavailability and solubility when incorporated into GRDDS. Reduced intestinal absorption of solid dose forms can be accomplished by the flotation mechanism. The novel fusion of bilayer and floating mechanism is demonstrated by the bilayer floating drug delivery device. It demonstrates the effective creation of a controlled release formulation. Bilayer floating tablets offer a sustained release layer formulation in addition to an immediate release. A attempt was made to explain the mechanism of FDDS, or floating bilayer, in the review. In order to accomplish regulated administration of various medications with predetermined release profiles, bi-layer tablets were developed. The pharmaceutical industry has been more interested in creating bilayer tablets over the past ten years as a way to improve patient compliance and convenience by combining two or more API in a single dose form.
