abstract
- Fondaparinux is the first synthetic selective Factor Xa inhibitor. Along with its antithrombotic efficacy, the safety of fondaparinux has been documented in several Phase II and III clinical trials, including the prevention of venous thromboembolism in patients undergoing major orthopaedic surgery or high-risk abdominal surgery, or in acutely ill medical patients with restricted mobility, and the treatment of patients with deep-vein thrombosis and pulmonary embolism. In all these indications, the safety of fondaparinux used according to its registered regimen was similar to that of reference comparators. In conclusion, due to its superior efficacy and satisfactory safety, fondaparinux may substantially improve the prevention and treatment of venous thrombosis.
