Abstract

The objective of the present study was to formulate the gastro-retentive floating tablets containing Ibuprofen, which would remain in stomach and/or upper part of GIT for prolonged period of time. Floating systems have low bulk density so that they can float on the gastric juice in the stomach. Ibuprofen is an anti inflammatory drug. On trial and error basis formulation design was done. Four different batches of floating tablets of Ibuprofen were prepared using HPMC, Xanthan gum, and gas generating agent sodium bicarbonate and citric acid. The tablets were characterized for the pre and post compression parameters such as friability, hardness, thickness, drug content, weight variation, in-vitro buoyancy studies and 13 hrs in-vitro drug release studies and the results were within the limits. From the results obtained, it was concluded that the optimized formulation F4 desired drug release properties and floating behavior. Keywords: Ibuprofen, HPMC K4M, gastro-retentive floating tablets, xanthan gum, sodium bicarbonate, citric acid.
