The role of betrixaban in the prevention of venous thromboembolism (VTE) in acutely medically ill patients and its efficacy and safety profiles are reviewed.
Acutely medically ill patients have a high risk of developing VTE during hospitalization, and this risk continues into the postdischarge phase. Extended-duration betrixaban therapy has been evaluated in a large clinical trial (the APEX trial) and in a meta-analysis of pooled data on acutely medically ill patients. These studies have shown positive outcomes when betrixaban was compared with conventional-duration subcutaneous enoxaparin therapy for prevention of VTE in acutely medically ill patients. In parallel with these results, oral betrixaban therapy was found to be associated with a rate of major bleeding comparable to that associated with subcutaneous enoxaparin therapy; however, betrixaban use was associated with a higher cumulative rate of major and clinically relevant nonmajor bleeding. In the APEX trial, the primary endpoint was not met in 1 of the prespecified cohorts, but betrixaban appeared to confer benefit in another cohort and in the overall study population. Certain populations of patients, including the elderly, are at high risk for bleeding (mainly attributable to altered pharmacokinetics and polypharmacy); such patients are not appropriate candidates for extended-duration betrixaban therapy. Betrixaban can be a potential option for VTE prevention in medical patients; however, drug interaction potential and third-party coverage should be evaluated prior to prescribing.
Betrixaban is an oral option for VTE prevention in medical patients.
综述贝曲西班在预防急性内科疾病患者静脉血栓栓塞症(VTE)中的作用及其疗效和安全性。
急性内科疾病患者在住院期间发生VTE的风险很高,且这种风险会持续到出院后阶段。在一项大型临床试验(APEX试验)以及对急性内科疾病患者汇总数据的荟萃分析中,已对延长疗程的贝曲西班治疗进行了评估。这些研究表明,在预防急性内科疾病患者VTE方面,将贝曲西班与传统疗程的皮下注射依诺肝素治疗进行比较时,取得了阳性结果。与这些结果同时出现的是,发现口服贝曲西班治疗的大出血发生率与皮下注射依诺肝素治疗相当;然而,使用贝曲西班与大出血和临床相关非大出血的累积发生率较高有关。在APEX试验中,预先设定的一个队列未达到主要终点,但贝曲西班在另一个队列和总体研究人群中似乎带来了益处。某些患者群体,包括老年人,出血风险很高(主要归因于药代动力学改变和多种药物并用);这类患者不适合接受延长疗程的贝曲西班治疗。贝曲西班可能是内科患者预防VTE的一个潜在选择;然而,在开处方前应评估药物相互作用的可能性和第三方保险范围。
贝曲西班是内科患者预防VTE的一种口服选择。
