A prothrombin time of 20.2 seconds and an INR of 2.65 indicate an increased risk for bleeding. Warfarin is an anticoagulant that inhibits Vitamin K-dependent clotting factor synthesis. Phytonadione (vitamin K) is the antidote for warfarin, and it should be administered to reverse the anticoagulant effect before surgery. Abciximab (ReoPro) and Ticlopidine (Ticlid) are antiplatelet medications and are not effective in addressing this issue. Protamine sulfate is the antidote for heparin, which is a different anticoagulant.
