新型選擇性的抑制第Xa因子抗凝血藥品-Fondaparinux

New Selective Inhibitor of Factor Xa Anticoagulant Drug-Fondaparinux

摘要


在治療急性冠狀動脈症候群(acute coronary syndrome, ACS),抗凝血藥品(anticoagulant agents)是主要的一部分。目前有四種注射型的抗凝血藥品分別爲傳統肝素(unfractionated heparin, UFH)、enoxaparin、bivalirudin及fondaparinux。Fondaparinux爲合成的pentasaccharide,可選擇性的抑制第Xa因子,在預防骨科下肢手術後引起靜脈血栓栓塞(venous thromboembolism, VTE),共有四個多中心、隨機分派、平行及雙盲的研究(PENTHIFRA、EPHESUS、PENTATHOLON及PENTAMAKS)的結果皆指出fondaparinux的療效優於enoxaparin。而關於fondaparinux用於急性冠狀動脈症候群之療效部分,則有兩個大型的臨床研究,分別爲OASIS-5(針對非ST段上升型急性冠狀動脈症候群或不穩定型心絞痛)及OASIS-6 (針對ST段上升型心肌梗塞)。在OASIS-5的研究結果指出,fondaparinux在主要臨床療效指標部分(在第九天之死亡、心肌梗塞或復發性的缺血性心臟疾病指標)不劣於enoxaparin,而在OASIS-6的研究結果指出,和對照組或傳統肝素相比,針對ST段上升型心肌梗塞,未接受再灌流(reperfusion)治療的患者,使用fondaparinux可降低死亡率或再次心肌梗塞的發生率,並且不會增加嚴重出血或中風的比率。結論:fondaparinux有其使用的方便性,對於急性冠狀動脈症候群的病患,排除接受立即性皮下冠狀動脈侵入性治療手術的病患,fondaparinux是抗凝血劑的另一個新選擇。

並列摘要


Anticoagulant therapy is a major component in the management of acute coronary syndromes (ACS). Four anticoagulant agents are currently commercially available for ACS, namely unfractionated heparin (UFH), enoxaparin, bivalirudin and fondaparinux. Fondaparinux is a synthetic pentasaccharide, selective indirect inhibitor of factor Xa. Based on the four multicenter studies were conducted as randomized, parallel-group, double-blind clinical trials (PENTHIFRA、EPHESUS、PENTATHOLON及PENTAMAKS), fondaparinux was shown to be efficacious in the prevention of venous thromboembolism (VTE) versus enoxaparin. Two pivotal studies have demonstrated the efficacy of fondaparinux as an anticoagulant in the setting of ACS, namely OASIS-5 in non-ST elevation ACS, and OASIS-6 in ST elevation myocardial infarction (MI). In OASIS-5, fondaparinux was shown to be noninferior to enoxaparin in terms of death, MI or refractory ischemia at 9 days. In conclusion, ST-elevation myocardial infarction (STEMI) patients who were not receiving reperfusion treatment, fondaparinux is a convenient and alternative anti-coagulation therapy.
