Drug information of ceprotin


Mechanism of effect

Converted to activated protein C (APC). APC is a serine protease which inactivates factors Va and VIIIa, limiting thrombotic formation. In vitro data also suggest inhibition of plasminogen activator inhibitor-1 (PAF-1) resulting in profibrinolytic activity, inhibition of macrophage production of tumor necrosis factor, blocking of leukocyte adhesion, and limitation of thrombin-induced inflammatory responses.
