Management of anticoagulants. The administration of warfarin is generally continued within the therapeutic range of the prothrombin time-international normalized ratio (PT-INR). For patients taking warfarin with low-thromboembolic risk, 3 days withdrawal of warfarin is performed. In heparin bridging therapy, the administration of warfarin is discontinued for 3 days, and heparin is intravenously administered for 2 days.
