Which outcome is associated with the interaction of Warfarin and CYP2C9 inducers?

  1. Bleeding risk

  2. Clotting risk

  3. No significant outcome

  4. Increased blood pressure

The correct answer is: Clotting risk

The interaction of Warfarin and CYP2C9 inducers can increase the risk of clotting, not bleeding. This is because Warfarin is a blood thinner, so when it is mixed with a drug that increases the activity of CYP2C9 enzymes, it can cause too much clotting in the blood. This is why options A, C, and D are incorrect, as they do not accurately reflect the interaction and its resulting outcome.
