Pharmacokinetic data from one 10-month old child receiving the 50 mg/ m2 daily dose indicated an AUC0-24hr within the same range as that observed in older children and adults at the 50 mg/ m2 and the 50 mg dose, respectively, while in one 6-month old child receiving the 50 mg/ m2 dose, the AUC0-24hr was somewhat higher.
