Which drugs prevent clot formation by decreasing blood coagulability?

Anticoagulants
Antifibrinolytic drugs
Hemorheologic drugs
Antiplatelet drugs

The correct answer is: Anticoagulants

Anticoagulants are drugs that decrease the blood's ability to clot, thus preventing clot formation. This is done by inhibiting the production or activity of clotting factors in the blood. The other options, while related to blood clotting, do not directly prevent clot formation by decreasing blood coagulability. Antifibrinolytic drugs work by promoting the breakdown of blood clots, rather than preventing their formation. Hemorheologic drugs improve blood flow but do not directly affect clot formation. Antiplatelet drugs prevent platelets from clumping together, but this alone does not decrease blood coagulability.
