The following mean (range) pharmacokinetic parameters are reported after continuous infusion of dopamine in premature and term neonatea (24-43 weken GA) (Bhatt-Mehta et al. 1991, Padbury et al. 1990, Zaritsky et al. 1988):
| Css (1 µg/kg/min) | n=14 | 16.5 ± 3.4 ng/ml |
| Css (8 µg/kg/min) | n=14 | 69.3 ± 11.6 ng/ml |
| t½ | n=11 | 6.9 (5-11) min |
| Cl | n=11 | 115 (62-168) ml/kg/min |
| Vd | n=11 | 1.8 (0.6-4) l/kg |
Gestational age and post-natal age or weight do not effect the clearance of dopamine in (preterm) neonates. The great inter-individual variation that is nevertheless seen is as yet not explained.
The renal clearance in children less than 2 years of age (mean 82.3 ± 27.7 ml / kg / min) is almost 2 times that in children over 2 years (mean 45.9 ± 17 mg / kg / min) (Notterman et al. 1990)
