Exogenous anticoagulant drugs

"Exogenous anticoagulant drugs" are medications administered to prevent or treat pathologic blood clots by interfering with various steps of the coagulation cascade. Common classes include heparins (unfractionated and low molecular weight), vitamin K antagonists, and direct oral anticoagulants (DOACs), which respectively target clotting factors, vitamin K metabolism, or thrombin/factor Xa directly. These drugs are critical for managing conditions like venous thromboembolism, atrial fibrillation, and for prophylaxis in high-risk scenarios. They pose significant bleeding risks and often require laboratory monitoring for safe and effective use.
