Evaluation of Intravenous Posaconazole Dosing and Pharmacokinetic Target Attainment in Pediatric Patients.

Limited data exist on intravenous (IV) posaconazole dosing and the risk for hepatotoxicity it confers to children. In this study, we evaluated dosing and resulting trough levels in 10 pediatric patients on IV posaconazole. A therapeutic level in these patients was achieved 95% of the time. We found a median minimum effective dose of 6.55 mg/kg of body weight. No correlation was found between the duration or posaconazole trough level and an increased alanine transaminase level.
