Floating drug delivery system: A novel apporach for delivery of drug on targated organ

The goal of this review on floating drug delivery systems (FDDS) was to compile latest data with a particular focus on the main mechanism of flotation for stomach retention. Drug delivery systems that float instantly when they come into contact with gastric fluids are promising approaches for increasing the bioavailability of drugs within absorption window in the stomach or upper small intestine. They are unstable in the intestinal or colonic environment and have low solubility at high pH values. The Current pharmaceutical scenario focuses on the development of sustained drug delivery systems to achieve required therapeutic concentration with less amount of dose. Oral delivery of the drug is the preferable drug delivery system. Because of the ease of administration, patient compliance and formulation flexibility. The ability to delay and control the emptying period of a dosage form in the stomach is an extremely variable process. For dosage forms that stay in the stomach for longer periods of time than standard dosage forms so the gastric transit time is a valuable asset for this system. The goal of this review article is to provide detailed information on the pharmaceutical basis of their design, classification, advantages, in vitro and in vivo evaluation parameters, and applications of floating systems. These systems can help with a variety of issues that arise during the development of a pharmaceutical dosage form, as well as the potential of FDDS in the future. This review article makes an attempt to introduce readers to current developments in floating drug delivery systems.
