standard intensity warfarin

The First Affiliated Hospital with Nanjing Medical University · FDA-approved active Small molecule ✓ Verified May 2026

standard intensity warfarin is a Vitamin K antagonist (VKA) Small molecule drug developed by The First Affiliated Hospital with Nanjing Medical University. It is currently FDA-approved for Atrial fibrillation for stroke prevention, Venous thromboembolism (DVT/PE) treatment and prevention, Mechanical heart valve thromboprophylaxis.

Warfarin inhibits vitamin K-dependent clotting factors (II, VII, IX, X) to reduce thrombus formation and prevent blood clots.

Warfarin is a small molecule used as a vitamin K antagonist in standard intensity. It is studied for various conditions, including Antiphospholipid Syndrome, Arterial Thrombosis, and Heart Valve Disease, often in combination with other antithrombotic therapies.

Mechanism of action

Warfarin acts as a vitamin K antagonist, blocking the enzyme vitamin K epoxide reductase and preventing the carboxylation of clotting factors II, VII, IX, and X in the liver. This reduces the production of functional coagulation factors and prolongs the prothrombin time (PT/INR), thereby decreasing the risk of thromboembolism. Standard intensity warfarin dosing is titrated to maintain an INR of 2–3 for most indications.
