In the late years, exploratory and innovative progressions have been made in the innovative work of novel medication conveyance frameworks by overcoming physiological inconveniences, for example, short gastric habitation times and capricious gastric purging times. A few methodologies are as of now used in the prolongation of the gastric habitation times, including floating medication conveyance frameworks, swelling and stretching frameworks, polymeric bioadhesive frameworks, adjusted shape frameworks, high-thickness frameworks and other deferred gastric exhausting gadgets. The administration of sickness through solution is entering another period in which developing number of novel medication conveyance frameworks are continuously utilized and are accessible for helpful utilization. Oral maintained discharge gastroretentive measurements structures offer numerous favorable circumstances for medications with assimilation from upper parts of gastrointestinal tract and for those acting mainly in the stomach, enhancing the bioavailability of the pharmaceutical. Floating Gastroretentive Drug Delivery Systems (FGRDDS) is one among the gastroretentive measurements structures used to accomplish delayed gastric living arrangement time. The reason for composing this audit on skimming medication conveyance frameworks (FGRDDS) was to arrange the late writing with unique concentrate on the important instrument of floatation to accomplish gastric maintenance. The late advancements of FGRDDS including the physiological and definition variables influencing gastric maintenance, methodologies to plan single-unit and numerous unit coasting frameworks, and their arrangement and detailing angles are secured in point of interest. This survey likewise compresses the in-vitro strategies, in vivo studies to assess the execution and application of floating frameworks, and applications of these frameworks.Keywords

In recent years scientific and technological advancements have been made in the research and development of novel drug delivery systems by overcoming physiological troubles such as short gastric residence times and unpredictable gastric emptying times. Floating drug delivery systems are designed to prolong the gastric residence time after oral administration, at particular site and controlling the release of drug especially useful for achieving controlled plasma level as well as improving bioavailability. Floating drug delivery systems are the systems which are retained in the stomach for a longer period of time and there by improve the bioavailability of drug. The single unit dosage forms have the disadvantage of a release all or nothing during emptying process while the multiple unit particulate system pass through the GIT to avoid the vagaries of gastric emptying and thus release the drug more uniformly. The uniform distribution of these multiple unit dosage forms along the GIT could result in more reproducible drug absorption and reduced risk of local irritation. The purpose of designing multiple-unit dosage form is to develop a reliable formulation that has all the advantages of a single-unit form and also is devoid of any of the above mentioned disadvantages of single unit formulations. This review explains briefly about advantages, disadvantages, mechanism, types, factors, evaluation and application of these systems.Keywords
