Presentation transcript:

Bivalirudin is Cleaved by Thrombin so that there is a Rapid Return to Hemostasis and a Safety Advantage Heparin’s effects on platelets and its reappearance as it dissociates from cells and proteins may explain the prolonged bleeding risk following discontinuation of heparin, when a return to normal hemostasis is essential. Angiomax® (bivalirudin) is cleaved by thrombin, allowing thrombin to quickly recover hemostatic activity upon discontinuation of Angiomax. The natural reversibility and the short, 25-minute half-life may explain the significantly lower bleeding rates seen in clinical trials. Key Message: The natural reversibility and the short, 25-minute half-life of Angiomax may explain the significantly lower bleeding rates seen in clinical trials. Heparin’s effects on platelets and its reappearance as it dissociates from cells and proteins may explain the prolonged bleeding risk following discontinuation of heparin, when a return to normal hemostasis is essential. Angiomax has a short half-life. It is actually cleaved by thrombin, allowing thrombin to quickly recover hemostatic activity upon discontinuation of Angiomax.
