Which medication is a direct oral anticoagulant used for long-term anticoagulation?

• A. Warfarin
• B. Dabigatran
• C. Heparin
• D. Enoxaparin

Answer: (B)

Direct oral anticoagulants are taken by mouth and provide long-term protection against clotting without routine INR monitoring. Dabigatran is a direct thrombin inhibitor among these agents and is used for long-term anticoagulation in conditions like nonvalvular atrial fibrillation and treatment of DVT/PE, offering an alternative to warfarin with more predictable effects. Warfarin also provides long-term anticoagulation but is a vitamin K antagonist that requires regular INR checks and dietary considerations. Heparin and enoxaparin are parenteral anticoagulants used mainly for acute or inpatient therapy, not typical for ongoing long-term oral use.
