AbstractThe new oral anticoagulants directly inhibit either thrombin (Dabigatran, Pradaxa®,) or activated Factor X (rivaroxaban, Xarelto®, and apixaban, Eliquis®) and have been approved for thromboprophylaxis after hip and knee replacement surgery and stroke prevention in non-valvular atrial fibrillation. Moreover, rivaroxaban has been approved for the treatment of deep venous thrombosis, prevention of pulmonary embolism and anticoagulation after acute myocardial infarction. The direct FXa-inhibitor edoxaban (Lixiana®) expects approval for the prevention of stroke in atrial fibrillation in Germany in 2014. The half lives of all direct anticoagulants range between 8 and 17 hours. Dabigatran (Pradaxa®) and rivaroxaban (Xarelto®) are mainly excreted by the kidneys, apixaban (Eliquis®) by the liver (75%) and edoxaban (Lixiana®) by the kidneys (40%) and the faeces in 60%. Prior to surgery a shorter cessation is expected compared to the vitamin k antagonists phenprocoumon (Marcumar®, Falithrom®) and warfarin (Coumadin®). For acute bleedings caused by the direct thrombin inhibitor dabigatran (Pradaxa®) hemodialysis is recommended to eliminate the drug from the plasma. Due to the high protein binding the direkt FXa-inhibitors rivaroxaban (Xarelto®) and apixaban (Eliquis®) can not be hemodialysed. For edoxaban (Lixiana®) no data on elimination by renal replacement therapy are available. In case of life-threatening bleeding the replacement of a prothrombin complex preparation (PCC) containing the factors II, VII, IX and X and, second line, activated factor concentrates as recombinant factor VIIa or activated prothrombin complex preparations are recommended. © Georg Thieme Verlag Stuttgart · New York.
