There has been a lot of trouble in absorption of drugs having narrow absorption window. Major physiological adversities to overcome include short residence time (GRT) and unpredictable gastric empting time (GET). According to previous studies it has been seen that differences in gastric physiology, such as gastric pH, and motility exhibit both intra as well as inter subject variability demonstrating significant impact on gastric retention time and drug delivery behavior. Various approaches are currently being used 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 empting devices. This review article focuses on the current technological development in FDDS with special emphasis on the principal mechanism of floatation and advantages to achieve gastric retention and its potential for oral controlled drug delivery.
