|Abstract:||Copyright © 2015 Wolters Kluwer Health, Inc. The purpose of this study was to evaluate the pulmonary and systemic pharmacokinetics of colistin following a single dose of nebulized colistimethate sodium (CMS) in mechanically ventilated neonates. We administered a single dose of nebulized CMS (approximately 120,000 IU/kg of CMS, equivalent to 4 mg/kg colistin base activity) to 6 ventilated neonates with ventilator-associated pneumonia. The median gestational age was 39 weeks (range, 32-39 weeks). Mean (±SD) tracheal aspirate colistin maximum concentration (C<inf>max</inf>), area under the concentration-time curve (AUC<inf>0-24</inf>) and t<inf>1/2</inf> were 24.0 ± 8.2 μg/mL, 147.6 ± 53.5 μg·hours/mL and 9.8 ± 5.5 hours, respectively. The plasma concentrations of colistin were low. In neonates, a single nebulized dose of CMS (120,000 IU) resulted in high local concentrations for at least 12 hours and low systemic concentrations of colistin. Twice daily nebulization might be more appropriate.|
