Dabigatran belongs to which class of anticoagulants?

• A. Direct thrombin inhibitors
• B. Factor Xa inhibitors
• C. Vitamin K antagonists
• D. Antiplatelet agents

Answer: (A)

Dabigatran is a direct thrombin inhibitor. It binds to thrombin (factor IIa) and blocks its ability to convert fibrinogen to fibrin, as well as thrombin’s role in activating platelets. This direct inhibition of thrombin distinguishes it from other anticoagulants in the options. Factor Xa inhibitors (like rivaroxaban, apixaban) prevent the generation of thrombin by inhibiting factor Xa. Vitamin K antagonists (like warfarin) reduce the synthesis of several clotting factors by interfering with vitamin K–dependent carboxylation. Antiplatelet agents (such as aspirin or clopidogrel) primarily affect platelets rather than the coagulation cascade. Dabigatran is a direct oral anticoagulant used for stroke prevention in nonvalvular atrial fibrillation and for treatment of DVT/PE.
