Multicenter StudyBioavailability of fondaparinux to critically ill patients.
Venous thromboembolism is a common problem in the intensive care unit (ICU). To decrease its incidence, prophylactic pharmacologic interventions are part of the ICU routine. However, common ICU conditions may impair the bioavailability of subcutaneously administered agents. The present study evaluates the bioavailability of prophylactic subcutaneous fondaparinux to critically ill patients. ⋯ Vasopressor therapy does not appear to affect fondaparinux bioavailability or to reduce anti-factor Xa levels. Subtherapeutic concentrations were detected during the first 48 hours of fondaparinux administration in hemodynamically stable patients. The clinical significance of reduced levels during the first 2 days of fondaparinux administration remains unknown.
