Keywords:Floating drug delivery systems, Sustained action, Swelling, Bioadhesive
Sustained- release system includes any drug delivery system that achieves a slow release of drug over an extended period of time and helps to improve therapy. The delivery system used for sustained action should only produce a sustained action at a predetermined rate by maintaining a constant and effective drug level in the body with undesirable side effects1.Several approaches are currently utilized in the prolongation of the GRT, including floating drug delivery systems (FDDS), swelling and expanding systems, polymeric bioadhesive systems, high-density systems, modified-shape systems and other delayed gastric emptying devices. In this review, current & recent developments of Stomach Specific FDDS are discussed.
