title: Lack of interaction between nizatidine and warfarin during chronic administration.
abstract: Nizatidine is a new antagonist of H2 receptors. The nizatidine warfarin interaction was investigated in healthy volunteers during chronic warfarin (mean warfarin dose: 5 +/- 0.9 mg/d) and nizatidine (300 mg/d) administration. Nizatidine coadministration did not increase the prothrombin time, kaolin-cephalin clotting time, and did not modify the activity of clotting factors II, VII, IX, X. Nizatidine did not influence the steady-state plasma warfarin concentration.
