Abstract
1. Although many studies have assessed changes to brain uptake of anti-epileptic drugs (AEDs) in chemically and electrically induced seizure models, there are limited data available on changes to brain uptake of AEDs in spontaneous seizure animal models, such as genetic absence epilepsy. 2. In the present study, the brain uptake of diazepam and phenytoin was assessed in a genetic mouse model of absence seizures harbouring a human GABA(A) receptor gamma2-subunit gene GABRG2 mutation (R43Q) and results were compared with those obtained during acute seizures induced by subcutaneous administration of pentylenetetrazole (PTZ; 90 mg/kg). Diazepam and phenytoin were administered intraperitoneally a..
