We report analysis of voriconazole (VRCZ) concentration of cerebrospinal fluid (CSF) during prophylactic use in children and adolescents with acute myelogenous leukemia. The median CSF/plasma ratio was 0.57 (range, 0.35–1.04). There was a significant positive correlation between the VRCZ concentrations in CSF and plasma. The CSF/blood ratio negatively correlated with age, body weight and VRCZ concentration in plasma and CSF. VRCZ is more highly transferred to CSF at low plasma concentrations, and the rate is lower at high plasma concentrations. The exact mechanism of VRCZ penetration though blood−brain barrier is not known.
