Although the use of dabigatran and rivaroxaban are increasing, data on the reversal of their effects are limited. The lack of reliable monitoring methods and specific reversal agents renders treatment strategies empirical, and as a result, treatment consists mainly of supportive measures. Therefore, we performed a systematic search of the PubMed database to find studies and reviews pertaining to oral anticoagulation reversal strategies. This review discusses current anticoagulation reversal recommendations for the oral anticoagulants warfarin, dabigatran, and rivaroxaban for patients at a heightened risk of bleeding, actively bleeding, or those in need of preprocedural anticoagulation reversal. We highlight the literature that shaped these recommendations and provide directions for future research to address knowledge gaps. Although reliable recommendations are available for anticoagulation reversal in patients treated with warfarin, guidance on the reversal of dabigatran and rivaroxaban is varied and equivocal. Given the increasing use of the newer agents, focused research is needed to identify effective reversal strategies and develop and implement an accurate method (assay) to guide reversal of the newer agents. Determining patient-specific factors that influence the effectiveness of reversal treatments and comparing the effectiveness of various treatment strategies are pertinent areas for future anticoagulation reversal research.
尽管达比加群和利伐沙班的使用日益增多,但关于其作用逆转的数据却很有限。缺乏可靠的监测方法和特定的逆转剂使得治疗策略只能凭经验制定,因此,治疗主要包括支持性措施。为此,我们对PubMed数据库进行了系统检索,以查找有关口服抗凝逆转策略的研究和综述。本综述讨论了针对出血风险增加、正在出血或需要在术前进行抗凝逆转的患者,目前对华法林、达比加群和利伐沙班这几种口服抗凝剂的抗凝逆转建议。我们着重介绍了形成这些建议的文献,并为未来填补知识空白的研究提供方向。虽然对于接受华法林治疗的患者已有可靠的抗凝逆转建议,但关于达比加群和利伐沙班逆转的指导意见却各不相同且模棱两可。鉴于新型药物的使用日益增加,需要开展有针对性的研究,以确定有效的逆转策略,并开发和实施一种准确的方法(检测手段)来指导新型药物的逆转。确定影响逆转治疗效果的患者特异性因素,并比较各种治疗策略的有效性,是未来抗凝逆转研究的相关领域。
