Reversal agents for direct oral anticoagulants (DOACs), including factor X inhibitors and direct thrombin inhibitors, are a major concern in clinical practice. After DOACs were introduced and became widely used as an alternative for vitamin K antagonists in the management of venous thromboembolism and nonvalvular atrial fibrillation, the need for effective reversal agents has increased, particularly for life-threatening bleeding episodes related to DOACs or to reverse medication effects during urgent interventions. In the absence of specific reversal agents, prothrombin complex concentrate (PCC) and activated PCC are reasonable options to reverse bleeding associated with DOACs. However, high-quality clinical evidence is lacking. Idarucizumab is the only agent approved by the US Food and Drug Administration to reverse the effects of dabigatran; andexanet alfa and ciraparantag are also under evaluation as reversal agents for DOACs. This review summarizes the current evidence for nonspecific and specific reversal of DOACs.
直接口服抗凝剂(DOACs)的逆转剂,包括X因子抑制剂和直接凝血酶抑制剂,是临床实践中的一个主要关注点。在DOACs被引入并广泛用作维生素K拮抗剂在静脉血栓栓塞和非瓣膜性心房颤动管理中的替代药物后,对有效逆转剂的需求增加了,特别是对于与DOACs相关的危及生命的出血事件或在紧急干预期间逆转药物作用。在没有特异性逆转剂的情况下,凝血酶原复合物浓缩物(PCC)和活化PCC是逆转与DOACs相关出血的合理选择。然而,缺乏高质量的临床证据。依达赛珠单抗是美国食品药品监督管理局批准的唯一可逆转达比加群作用的药物;安多昔单抗和西帕曲坦也正在作为DOACs的逆转剂进行评估。本综述总结了目前关于DOACs非特异性和特异性逆转的证据。
