Abstract

Direct oral anticoagulants (DOAC) are an attractive therapeutic option for anticoagulant treatment in the setting of venous thromboembolism or non-valvular atrial fibrillation. These drugs overall appear to have a lower risk of life-threatening hemorrhage than the vitamin K antagonists. In addition, they demonstrate more predictable and stable pharmacokinetics. Measurement of the degree of anticoagulation is desirable in patients with DOAC-associated hemorrhage, but commonly available coagulation assays show poor sensitivity for degree of DOAC effect. DOAC-specific tests are time consuming and not widely available. All coagulation tests should be interpreted considering the timing of last intake and renal function. When life-threatening bleeding occurs, hemostasis should be restored as rapidly as possible. Non-specific prohemostatic drugs may have a role in DOAC reversal, and specific antidotes are at different stages of development. In this review, we provide a summary of DOAC characteristics and an overview of the different therapeutic options available for DOAC reversal.

摘要

直接口服抗凝剂(DOAC)是静脉血栓栓塞或非瓣膜性心房颤动患者抗凝治疗的一种有吸引力的治疗选择。总体而言,这些药物出现危及生命出血的风险似乎低于维生素K拮抗剂。此外,它们表现出更可预测和稳定的药代动力学。对于DOAC相关出血的患者,抗凝程度的测定是可取的,但常用的凝血试验对DOAC效应程度的敏感性较差。DOAC特异性检测耗时且应用不广泛。所有凝血试验的解读都应考虑末次服药时间和肾功能。当发生危及生命的出血时,应尽快恢复止血。非特异性促止血药物可能在DOAC逆转中发挥作用,特异性解毒剂正处于不同的研发阶段。在本综述中,我们总结了DOAC的特点,并概述了可用于DOAC逆转的不同治疗选择。
