Which medication must be prescribed for a patient to manage anticoagulation therapy?

1. Aspirin

2. Warfarin

3. Clopidogrel

4. Ibuprofen

The correct answer is: Warfarin

Warfarin is a medication that is specifically designed for anticoagulation therapy, which is the prevention of blood clots. It works by inhibiting vitamin K-dependent clotting factors in the liver, effectively reducing the blood's ability to clot and therefore managing conditions such as deep vein thrombosis, pulmonary embolism, and preventing strokes in patients with atrial fibrillation. While the other medications listed may have anticoagulant effects or be used for cardiovascular health, they are not primarily indicated for managing anticoagulation therapy in the way that Warfarin is. Aspirin is an antiplatelet agent, which helps prevent platelets from clumping together, but it does not provide the same level of anticoagulation as Warfarin. Clopidogrel is also an antiplatelet medication, and similarly, while it plays a role in preventing blood clots, it is not a primary medication for managing anticoagulation therapy. Ibuprofen, on the other hand, is a nonsteroidal anti-inflammatory drug (NSAID) that is used for pain relief and inflammation, and it does not serve the purpose of anticoagulation. Therefore, Warfarin is the most appropriate choice for patients requiring management of anticoagulation therapy
