Abstract
To compare the marked hypoprothrombinemic augmentation in man of racemic warfarin sodium by the pyrazolons phenylbutazone and sulfinpyrazone with that of the coumarin anticoagulant phenprocoumon, these interactions were studied prospectively in six normal subjects. Large single doses of racemic phenprocoumon, 0.6 mg/kg orally, were administered with and without daily phenylbutazone, 300 mg, or sulfinpyrazone, 400 mg, beginning three days before phenprocoumon and continuing for 14 days. Daily blood samples were drawn for phenprocoumon content and one-stage prothrombin time. Phenylbutazone markedly increased both the phenprocoumon concentrations and prothrombin times, whereas sulfinpyrazone did not.
