Floating-mucoadhesive drug delivery system integrates gastric retention and mucoadhesion to extend the gastric residence time, and therefore, drug release is maintained at the absorption site. The present review addresses the strategies of formulations, mechanism of buoyancy and mucoadhesion, the variables that are influenced, approaches to characterization and the future of floating-mucoadhesive tablets (FMTs) to deliver gastric-absorbed drugs. Gastric retention improves solubility and bioavailability of drugs with low absorption half-lives and pH-sensitive drugs. FMTs make use of low density excipients and gas generating agents to realize buoyancy, and mucoadhesive polymers enhance mucosa tightness adhesion to gastric mucosa. We are summing up design parameters like the type of polymer, tablet geometry and swelling behavior. Issues like fluctuation of gastric emptying, food effect and patient to patient differences are emphasized. There is preclinical and clinical evidence of better pharmacokinetic characteristics of model drugs such as antibiotics, antidiabetics and agents with narrow absorption windows such as cardiovascular agents. Future trends and regulatory issues such as the incorporation of nanotechnology and in-situ gelling systems are given. The review offers an elaborate guide to pharmaceutical scientists and formulators who seek to improve the oral bioavailability by adopting gastroretentive approaches.
