Abstract
Triple bromide elixir was used as an adjunctive antiepileptic drug in 11 children whose seizure disorders were intractable to other antiepileptic therapy. The patients' ages ranged from 2 to 17 years. The seizure disorders treated included photosensitive epilepsy (one case), acquired epileptic aphasia (one case), Lennox-Gastaut syndrome (three cases), and symptomatic localization-related epilepsies (six cases). Two patients' seizures completely stopped with bromide therapy. Four patients had a significant and sustained improvement on bromide therapy, while three more had a transient improvement. In these six patients with complete or significant control, the mean therapeutic dose was 33 mg bromide/kg daily, and the mean therapeutic serum concentration was 14.1 mmol/L (range, 4 to 30.5 mmol/L). The combination of bromide with valproate appeared to be particularly effective in these patients. Toxicity was minimal, and in only one patient was the medication stopped, because of anorexia and weight loss. Given the low cost, long half-life, and minimal toxicity when serum bromide concentrations are followed, bromide therapy should be considered as adjunctive antiepileptic drug therapy for patients whose seizures are intractable to other drugs.
