title: The interaction of warfarin with antacid constituents in the gut.
abstract: A study was made of the effect of 4 constituents of antacid preparations on the absorption of the coumarin derivate warfarin sodium using an in vitro experimental model. The constituents tested were activated dimethiocone (a silicone) magnesium trisilicate, bismuth carbonate and the adsorbant, kaolin. Slight decreased intestinal absorption was shown by magnesium trisilicate (19%) and bismuth carbonate (7%), the other 2 components showing no effects.
