N = Number of subjects
GA = Gestational age (weeks)
BW = Birth weight (g)
t½ = Terminal half life of elimination (hours)
CL = Clearance (ml/min/kg)
V = Volume of distribution (L/kg)
Cmax = Maximum serum concentration (µg/ml)
AUC = area under the curve (ug*hr/ml)
These results were reported as a formula, based on the population PK model, to calculate PK parameters
