After a single intravenous administration of 1 mg/kg, Pokela et al. 1992 and Hamunen et al. 1993 found the following pharmacokinetic parameters:
| Age | n= | t½ (hour) | Cl (ml/min/kg) | Vd (l/kg) | Reference |
| 6 hours -5 months (including 5 preterme neonates) |
21 | 3,3-31,7 | 4,1-34,9 | 3,3-11,0 | Pokela et al. 1992 |
| 4-6 years | 20 | 3,0 | 10,4 | 2,8 | Hamunen et al. 1993 |
In addition, Jacobsen et al. 1988 found after single intravenous administration of 1 mg/kg to 10 children 7-13 years of age a mean Cmax of 2800 nmol/L reached after an average of 5 minutes (tmax). Based on the concentration time curves, a t½ of 3-4 hours was estimated.
