Resistance to antiepileptic drugs (AEDs) is a major problem in epilepsy therapy.
Rodent models with resistant spontaneous seizures are only rarely used in drug development.
Induction of acute seizures in epileptic rodents could provide a surrogate model of resistance.
We evaluated the timed i.v. pentylenetetrazole infusion seizure test in epileptic mice.
Except valproate, AEDs examined were not less effective in epileptic vs. nonepileptic mice.
