Pharmacokinetics in children

The kinetics in adolescents aged 12 years and up are comparable to the kinetics in adults.

The following pharmacokinetic parameters were found in the absence of anti-epileptics that affect the kinetics of perampanel (Renfroe 2019):

Age n= Cl/F (L/hour)
12-17 years 79 0.7±0.4
7-11 years 12 1.0±0.4
2-6 years 14 0.7±0.4

In combination with enzyme-inducing anti-epileptics (carbamazepine, oxcarbazepine and phenytoin) the following values were found (Renfroe 2019):

Age n= Cl/F (L/hour)
12-17 years 73 1.6±0.8
7-11 years 10 1.9±0.5
2-6 years 6 1.7±1.2
