Warfarin, Eliquis, Pradaxa, Plavix, and Xarelto are all examples of what?

• A. Blood thinners
• B. Pain relievers
• C. Antibiotics
• D. Antihistamines

Answer: (A)

These medications all reduce the blood’s ability to form clots, so they’re commonly called blood thinners. Warfarin works by blocking vitamin K–dependent clotting factors, which slows the overall clotting process. The direct oral anticoagulants Eliquis and Xarelto inhibit factor Xa, a key step in making thrombin and forming clots. Pradaxa directly inhibits thrombin, another essential enzyme in clot formation. Plavix is an antiplatelet that prevents platelets from sticking together, interrupting the first step of clot formation. While they all aim to prevent clots, they achieve this through different mechanisms—some affect clotting factors in the blood, others prevent platelet aggregation. The other options describe drugs with different primary uses (pain relief, infection control, allergy relief) and don’t describe agents that prevent clot formation.
