Abstract

Based on the initial successful use of felbamate for infantile spasms in an infant with tuberous sclerosis, three additional infants with infantile spasms of different etiologies who had failed conventional therapies were treated with felbamate. Three of the four patients have shown complete resolution of infantile spasms. All responding patients did so within 1 week of starting felbamate. The one treatment failure had an initial reduction of seizure frequency and severity but has not maintained that response long term. Controlled studies are needed to firmly establish that felbamate is both safe and effective for the treatment of infantile spasms. As these cases document, felbamate is currently available for use in infantile spasms, and the frequent conversion of infantile spasms to Lennox-Gastaut syndrome, for which felbamate is approved, makes its use in infantile spasms logical.
