Description: YM-75466 is a factor Xa inhibitor potentially for the treatment of thrombosis. YM-75466 did not prolong coagulation time even at the dose which exerted significant antithrombotic effects, while it decreased TAT level in plasma in a dose-dependent manner. YM-75466 exerted anti-FXa activity but not anti-thrombin activity. YM-75466, unlike heparin, exerts its antithrombotic effect through specific inhibition of FXa without any effect on thrombin.
