Question

Which is the following is orally active direct Xa inhibitor?

• A. Rivaroxaban
• B. Agrataban
• C. Dabigatran
• D. Bilverudin

Answer 1

The Correct Option is A

The question asks which of the listed options is an orally active direct Factor Xa inhibitor. Let's analyze each option:

1. Rivaroxaban: This is a well-known anticoagulant that works as a direct Factor Xa inhibitor and is administered orally.
2. Agrataban: This option is a mix-up with argatroban, which is a direct thrombin inhibitor, not a Factor Xa inhibitor, and is used intravenously.
3. Dabigatran: This is a direct thrombin inhibitor, not a Factor Xa inhibitor, and although it is orally active, it does not target Factor Xa.
4. Bilverudin: This appears to be a misinterpretation of bivalirudin, which is also a direct thrombin inhibitor used intravenously, not targeting Factor Xa.

Given the analysis above, Rivaroxaban is the correct choice as it is an orally active direct Factor Xa inhibitor. Therefore, the correct answer is:

Rivaroxaban
