Patients admitted with acute medical conditions are at prolonged risk for venous thrombosis. The efficacy and safety, and the appropriate duration of thromboprophylaxis have not been clearly determined. In recent years, direct coagulation factor inhibitors have been successfully tested for the prevention and treatment of arterial and venous thromboembolism. Betrixaban is a novel direct inhibitor of factor Xa with a noteworthy pharmacological feature: limited renal clearance. Areas covered: This review focuses on the pharmacological profile of Betrixaban, including its clinical efficacy and safety. It also covers the results of the pivotal APEX trial assessing the safety and efficacy of betrixaban for extended thromboprophylaxis in patients with acute medical conditions. Expert opinion: The role of extended thromboprophylaxis in acutely ill medical patients is subject to debate. The beneficial results in terms of VTE prevention were offset by the relevant increase in major bleeding. Betrixaban is the only direct oral anticoagulant to have shown a favorable risk-benefit profile in this setting especially in patients at higher risk for thrombosis.
患有急性内科疾病的患者存在长期静脉血栓形成的风险。其疗效和安全性,以及适当的预防血栓形成的持续时间尚未明确。近年来,直接凝血因子抑制剂已成功用于预防和治疗动脉和静脉血栓栓塞。贝曲西班是一种新型的直接因子 Xa 抑制剂,具有显著的药理学特征:肾清除率有限。涵盖领域:本综述重点介绍了贝曲西班的药理学特性,包括其临床疗效和安全性。它还涵盖了关键的 APEX 试验的结果,该试验评估了贝曲西班在急性内科疾病患者中延长预防血栓形成的安全性和有效性。专家意见:延长急性内科疾病患者的预防血栓形成的时间作用存在争议。在预防 VTE 方面的有益结果被主要出血的相关增加所抵消。贝曲西班是唯一一种在这种情况下显示出有利的风险效益比的直接口服抗凝剂,特别是在血栓形成风险较高的患者中。
