  • Warfarin is a widely used oral anticoagulant agent used to treat thromboembolic disease. The purpose of this study was to develop the efficient assay method of warfarin sodium i n human plasma and to assess the pharmacokinetic profile of the warfarin in healthy Korean volunteers. The pharmacokinetics of warfarin administered orally was evaluated after a dose of 10 mg. Warfarin in plasma was assayed using a specific HPLC method with UV absorbance at 304 nm. AUC was 46.33${\pm}9.95{\mu}g/ml.hr$, $C_{max}$ $1.22{\pm}0.22{\mu}g/ml, $T_{max}$$2.50{\pm}1.41$ hr and half-life $43.49{\pm}4.33$ hr. $T_{max}$ was slightly shorter than that in Caucasian (3~9 hr), whereas the half-life was longer than that in Caucasian (10~45 hr, mean: 36 hr). These results suggest that warfarin may have a longer duration in Korean than in Caucasian.
