Introduction and Application of Bilayer Floating Tablet: A Brief Review

Bilayer tablet is an innovation period for the successful advancement of controlled release formulation as well as a variety of features to produce a successful drug delivery system technique. Controlled release dose forms have been widely employed to improve treatment with a number of key medications. Inclusion of drugs in controlled release gastro-retentive dosage forms that can remain in the gastric region for several hours would significantly increase drug bioavailability, reduce drug waste, and improve the solubility of drugs that are less soluble in high pH environments. Floating drug delivery systems, swelling and expanding systems, polymeric bio adhesive systems, high-density systems, changed form systems, and other postponed gastric systems are now used in the extension of Gastric Retention Time.
