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.
The anticoagulant response to warfarin is influenced both by pharmacokinetic factors, including drug interactions that affect its absorption or metabolic clearance, and by pharmacodynamic factors, which alter the hemostatic response to given concentrations of the drug.
