Recent research reports that bromide may show promising results in treating patients with SCN1A-associated Dravet syndrome with intractable seizures. Bromide is not FDA-approved for use in the United States. But it is among anticonvulsants available in Germany and other European countries.
Jan Lotte and colleagues at the Sch√∂n Klinik in Vogtareuth, Germany, conducted a retrospective analysis of patient medical histories and structured parent interviews on a cohort of Dravet patients 2 to 25 years of age with SCN1A mutations. A total of twenty-one anticonvulsant drugs, including bromide, were found in the analysis. Most of the anticonvulsants provided at least some degree of seizure control. The investigators also found that fifteen of the twenty-one drugs were associated with an aggravation of the condition. Aggravation was not observed with six of the medications, including bromide.

"Treatment with this medication achieved results comparable to clobazam and clearly above valproate, both first-line therapies for Dravet syndrome. We think that bromide may have a particular role in treating Dravet patients with SCN1A mutations with intractable seizures."
Bromide builds up slowly in the bloodstream taking time to achieve therapeutic levels. Usually the drug is well tolerated, significant toxic side effects are seldom to be found.
