Abstract:
The purpose of writing this review on floating drug delivery systems was special focus on the principle mechanism of floatation to achieve gastric retention. Conventional oral dosage forms has short residence times & unpredictable gastric emptying time. The idea of gastric retention comes from the need to localize drugs at a specific region of gastrointestinal tract (GIT) such as stomach in the body. Many drugs get absorbed only in the upper intestinal tract, designing such molecules as once-daily formulations are exclusive for these molecules. Thus GI retention platforms had emerged. Gastroretentive drug delivery systems are designed to be retained in the stomach for a prolonged time. Gastroretentive drug delivery systems have potential for use as controlled release drug delivery system. The use of floating drug delivery system is one method to achieve prolonged gastric residence times, providing opportunity for both local & systemic drug action. Thus, gastroretention could help to provide greater availability of new products and consequently improved therapeutic activity and substantial benefits to patients. This article aims at reviewing the floating drug delivery system including types, approaches for designing the floating dosage form, advantages & disadvantages of FDDS.

ABSTRACT
As pharmaceutical scientists are attaining a better understanding of biochemical and physicochemical properties related to the drug action, the drug delivery systems are becoming simple. Recent advances in Novel Drug Delivery Systems (NDDS) aim for designing dosage forms, convenient to be manufactured and administered, free of side effects, offering immediate release and enhanced bioavailability, so as to achieve better patient compliance Oral delivery is currently the gold standard in the pharmaceutical industry where it is regarded as the safest, most convenient and most economical method of drug delivery. Fast dissolving tablet is designed to allow administration of an oral solid dose form in the absence of water or fluid intake. Such tablets when put on the tongue. it readily dissolve or disintegrate in the saliva without chewing or water within <60 seconds. Fast- or mouth dissolving tablets have been formulated for pediatric, geriatric, and bedridden patients and for active patients who are busy and traveling and may not have access to water. This review includes requirements for fast disintegrating tablets, sailent features, advantages, limitations, challenges in formulation, various technologies developed for fast disintegrating tablets, patented technologies, evaluation methods and various marketed products.
