Pharmacokinetics of anidulafungin during venovenous extracorporeal membrane oxygenation

Echinocandins are currently considered the first-line treatment for invasive candidiasis (IC) in the intensive care unit (ICU) [1, 2]. However, extracorporeal membrane oxygenation (ECMO), a rescue therapy used in patients with severe acute respiratory distress syndrome (ARDS) [3], could alter the pharmacokinetics of certain drugs [4]. We prescribed anidulafungin for suspected IC in a patient with severe ARDS on ECMO and measured the plasma concentrations of the drug using high-performance liquid chromatography (HPLC).
