The Correct Answer is B!

 

There are a number of oral anticoagulant agents now used for the prevention of thromboembolic events in patients with atrial fibrillation.

Which one is a direct thrombin inhibitor?

A. Edoxaban
B. Dabigatran
C. Apixiban
D. Rivoraxaban

Rationale:

The correct answer is dabigatran. The new oral anticoagulants have been approved for the prevention of embolic events in selected patients with atrial fibrillation. They have a more selective mechanism of action than warfarin. Dabigatran is a direct thrombin inhibitor and both apixiban and rivoraxaban are factor Xa inhibitors.
