Treatment of seizures in acute intermittent porphyria: safety and efficacy of gabapentin

Patients needing chronic therapy often experience acute porphyric attacks due to increased hepatic metabolism induced by the antiepileptic drugs themselves. Gabapentin is a new antiepileptic drug not appreciably metabolized by the liver in humans, and it appears to be safe and effective in the maintenance therapy of epilepsy in these patients. We report a patient affected by partial and generalized seizures in the course of acute intermittent porphyria, who was safely and successfully treated with gabapentin
