Gastro retentive systems can remain in the stomach region for several hours and can significantly prolong the gastric residence time of drugs thereby improving the drug bio-availability. Floating Drug Delivery Systems promises to be a potential approach for gastric retention. Floating tablets of Glycerrhiza extract were prepared by direct compression method using HPMC of various grades and sodium bicarbonate as gas forming agent. Floating tablets were evaluated for floating lag time, drug content and invitro dissolution profile. The lag time ranged between 29-4140 sec and buoyancy time for the formulations remained 24 hrs. The drug content was found to be under limits, Drug release percentage was between 31.56-50.54 in 8 hrs and kinetic studies showed the formulations fitting all the models similarly. From the study it is evident that a promising controlled release by floating tablets of Glycerrhiza extract can be developed and different excipient ratios affected the drug release and floating time. Further detailed investigations are required to establish the invivo efficacy of the formulations.
