WebbDeficiency in protein C-mediated anticoagulant response: warfarin sodium reduces the synthesis of the naturally occurring anticoagulants, protein C and protein S. Hereditary or acquired deficiencies of protein C or its cofactor, protein S, have been associated with tissue necrosis following warfarin administration. WebbWarfarin, also known by its trade name Coumadin, is an anticoagulant that inhibits the activation of vitamin K, decreasing the levels of vitamin K-dependent clotting factors in blood. These include prothrombotic factors like Factor II, VII, IX, and X, as well as the thrombolytic factors Protein C and S.
