Population Pharmacokinetic Assessment of Vancomycin Dosing in the Large Pediatric Patient.

The most appropriate vancomycin dosing strategy in pediatric patients weighing ≥70 kg (weight based versus non-weight based) to achieve an area under the concentration-time curve (AUC) of ≥400 mg·liter/h and a trough concentration of <20 mg/liter is not known. Population pharmacokinetic analysis determined that dosing of vancomycin should be weight based using fat-free mass, with appropriate adjustment for kidney dysfunction.
