Pharmacokinetics in children
Pharmacokinetic data from research in children has shown that the plasma concentrations of bosentan were lower on average than in adult patients and were not raised by increasing the dose of Tracleer further, beyond 2 mg/kg twice daily.
The study by Barst et al. (n=18, ages 3 to 15 years) stated the following pharmacokinetic parameters after a single dose of bosentan:
| Dose | Cmax (ng/ml) | Tmax (hours) | T½ (hours) |
|---|---|---|---|
| 31.25 mg | 959 | 1.0 | 4.7 |
| 62.5 mg | 815 | 2.5 | 5.3 |
| 125 mg | 1709 | 4.0 | 4.2 |
After multiple doses, the following average pharmacokinetic parameters were stated:
| Dose | Cmax (ng/ml) | Tmax (hours) | T½ (hours) |
|---|---|---|---|
| 62.5 mg/day in 2 doses | 685 | 2.5 | 6.0 |
| 125 mg/day in 2 doses | 1136 | 1.0 | 5.6 |
| 250 mg/day in 2 doses | 1200 | 1.8 | 5.3 |
