By preventing the blood clots that trigger heart attack and stroke, the anticoagulant drug warfarin (CoumadinÂ®) saves countless lives. Doctors must regularly monitor patientsâ blood levels in order to prescribe a high enough dose of warfarin to prevent deadly blood clots, but not an excessive dose that could lead to fatal hemorrhage.
Warfarin is the oral anticoagulant most frequently used to control and prevent thromboembolic disorders. Prescribing the dose that both avoids hemorrhagic complications and achieves sufficient suppression of thrombosis requires a thorough understanding of the drug's unique pharmacology. Warfarin has a complex dose-response relationship that makes safe and effective use a challenge. For most indications, the dose is adjusted to maintain the patient's International Normalized Ratio (INR) at 2 to 3.
