Question

Quizplus · Accepted Answer

Coumadin (also known as warfarin) interferes with the hepatic utilization of vitamin K in the synthesis of prothrombin, which is necessary for blood clotting. This makes it an effective anticoagulant. Clopidogrel (Plavix) is an antiplatelet medication, not an anticoagulant. Digoxin is a medication used to treat heart failure and certain arrhythmias, not an anticoagulant. Heparin is an anticoagulant, but it works by binding to antithrombin III, not by interfering with vitamin K utilization.
