Abstract

Floating drug delivery Systems has received considerable interest in the past few decades as they can overcome the drawbacks of conventional drug delivery system like frequent dosing, low bioavailability etc. relative to fast gastric-emptying time. An optimum floating drug delivery System can be defined as a systemthat remains in the stomach for sufficient interval of time and releases the active medicament in a sustained manner. These remain floating on the gastric contents. Thus resulting in prolonged pharmacological effect thus improving the bioavailability of drug. The aim of writing this review on gastro retentive and floating Tablet was to compile the new literature with the principle, Advantages and classification of the floating tablets, method of preparation, evaluation techniques, list of drugs formulated as floating tablets, formulation evaluation and future scope of floating tablets.

Keywords: Floating tablets, bioavailability, Gastro retentive, prolong release.
