NOAC with reversal agent?

• A. Apixaban
• B. Dabigatran
• C. Edoxaban
• D. Rivaroxaban

Answer: (B)

The concept here is reversal options for NOACs in the setting of major bleeding or urgent procedures. Dabigatran has a dedicated reversal agent: idarucizumab. This antidote binds dabigatran with high affinity and neutralizes its anticoagulant effect quickly, allowing rapid control of bleeding or safe timing of procedures. That makes dabigatran the best answer because it is the NOAC with a specific reversal agent readily available. For the other NOACs, reversal strategies exist or have been developed (such as reversal agents for factor Xa inhibitors), but they were not as universally available or established at the time these questions were written, so they aren’t the best match to this prompt.
