[Hemostasis and blood coagulation revisited: mechanisms and therapeutic implications].

The number of oral anti-thrombotic agents is steadily expanding. Major advances have recently been made in the understanding of haemostasis and blood coagulation processes. This paper reviews the mechanisms of haemostasis and thrombosis and the molecules used for the treatment of arterial and venous thrombotic disorders with a special emphasis on recently introduced agents (Clopidogrel, Pentasaccharide, Melagatran).
