Summary
Fondaparinux is a parenteral anticoagulant drug and is approved for the prevention of venous
thromboembolism in high risk medical patients. A relevant proportion of medical patients
have moderate to severe renal insufficiency, which is an independent risk factor for
bleeding. This risk may be further increased when low molecular weight heparin or
fondaparinux are administered in patients with severe renal insufficiency, defined by a
creatinine clearance of lower than 30 mL/min. No clear indications are available to reduce
such risk in patients who require thromboprophylaxis. A lower dose of fondaparinux, 1. 5 mg
daily, has been recently approved for the prevention of venous thromboembolism in the
specific population of patients with a creatinine clearance between 20 and 50 mL/min
(European Marketing Authorization). However, there are to our knowledge no clinical studies
that have assessed the safety and efficacy of this reduced dosage in medical patients.
