Floating matrix tablets were developed to prolong gastric residence time and increase drug absorption further increasing the bioavailability. Various forms of gastro retentive drug delivery system, such as floating and non-floating. Floating tablets was formulated to increase gastric residence and there by improve its therapeutic efficacy. By using different polymers such as carbopol, guargum, HPMC K100, HPMCK4 etc. Formulated tablets showed satisfactory results for various post compression evaluation parameters like thickness, hardness, weight variation, floating lag time, total floating time, content uniformity and in vitro drug release.
