Q: Bleeding due to displacement of warfarin from protein-binding sites is a type of ________ drug interaction.
  • A. oral antidiabetic

  • C. antihypertensive
  • D. analgesic
Correct Answer: Option B - Warfarin is an anticoagulant medication. It works by inhibiting Vitamin K-dependent clotting factors. When warfarin is displaced from its protein-binding sites by another drug its concentration in the blood stream increase, leading to an increased risk of bleeding. This type of drug interaction is known as a displacement interaction.
