FLOATING DRUG DELIVERY SYSTEM: A NOVEL APPROACH

Floating Drug Delivery System is a Novel drug delivery system used to achieve the gastric retention of dosage form which will leads to prolonged release and action of drugs. This delivery system retained in the stomach for a longer period of time and thereby improves the bioavailability of drugs. Several approaches are currently used in the prolongation of gastric residence time (GRT) including floating drug delivery system also called as hydrodynamically balanced system, swelling and expanding system, polymeric bioadhesive systems, high density systems etc. This review also contains current and recent advances in floating drug delivery systems.
