INTRODUCTION: Patients undergoing major orthopedic surgery face considerable risk of venous thromboembolism (VTE), which may be fatal unless they receive prophylactic treatment. Fondaparinux sodium is a new antithrombotic agent that is indicated for prophylaxis of VTE after major orthopedic surgery. This paper presents a cost-effectiveness analysis of fondaparinux sodium and enoxaparin sodium, the latter being the most commonly used agent for prophylaxis of VTE. METHODS: The analysis is based on an international simulation model, using Norwegian unit costs, and Norwegian data of 55 000 patients undergoing orthopedic surgery between 1999 and 2001. We estimated the expected incidence of VTE and VTE-related deaths, and expected costs of VTE-related care for each of the two prophylactic agents for different periods. RESULTS AND CONCLUSION: The results indicate that fondaparinux sodium is likely to be more effective than enoxaparin sodium in preventing the incidence of VTE. By day 90, fondaparinux sodium is expected to avoid 180 more VTE events, and between 8 and 33 more VTE-related deaths per 10,000 patients than enoxaparin sodium. Fondaparinux sodium is also a cost-saving option in short follow-up periods for hip fracture surgery. For extended follow-up periods (i.e. 5 years), fondaparinux sodium is also likely to represent the lower cost treatment option after total knee and hip replacement. The sensitivity analyses show that the main results are robust to changes in the most important parameters. Results are, however, sensitive to the price difference between the two drugs. 相似文献

Fondaparinux sodium (fondaparinux) is a synthetic sulfated pentasaccharide anticoagulant developed from the antithrombin binding moiety of heparin. Through the activation of antithrombin it inhibits Factor Xa, the activation of thrombin, and the subsequent coagulation cascade. Fondaparinux is approved in Europe and the US for the treatment of acute venous thromboembolism (VTE), including both deep vein thrombosis (DVT) and pulmonary embolism (PE), when used in conjunction with warfarin. In phase III clinical trials, subcutaneous fondaparinux was noninferior to subcutaneous enoxaparin or intravenous unfractionated heparin (UFH) in the prevention of recurrent symptomatic VTE in patients with acute DVT and PE, respectively, and equally well tolerated. It thus provides a valuable alternative to UFH and low-molecular weight heparins in the treatment of acute VTE, particularly in the outpatient setting. 相似文献

Fondaparinux sodium (Arixtra) is a synthetic, sulfated pentasaccharide, selective factor Xa inhibitor that is indicated in Europe for preventing thrombus formation in patients with acute coronary syndromes (ACS; the focus of this review), including those with ST-segment elevation myocardial infarction (STEMI), non-STEMI (NSTEMI), or unstable angina.The large (n = 20,078), well designed OASIS-5 trial showed that subcutaneous fondaparinux 2.5 mg/day for 12,000) OASIS-6 trial. There were no differences in the incidence of major bleeding between these groups, resulting in a benefit : risk balance favoring fondaparinux. The specificity and selectivity of fondaparinux, combined with its long half-life and 100% bioavailability, allows once-daily anticoagulation without the need for monitoring activated clotting time. Subcutaneous fondaparinux was noninferior to enoxaparin treatment in patients with unstable angina or NSTEMI, and was more effective than usual care in those with STEMI. Fondaparinux has a favorable tolerability profile, particularly with regard to the risk of major bleeding, and limited data suggest that it is more cost effective than enoxaparin in the short term. Thus, overall, clinical evidence suggests that fondaparinux has a valuable place in the treatment of patients with ACS. 相似文献
