Topiramate efficacy in infancy.

Topiramate is a sulfamate-substituted monosaccharide that has demonstrated efficacy as an antiepileptic drug in adults with partial onset seizures. Experience in children has been limited, but early reports have supported its safety and effectiveness in children as young as 2 years of age. In two infants ages 12 and 9 months, respectively, with partial seizures, the authors report excellent efficacy with good tolerability at doses up to 7.7 mg/kg. Although long-term safety and possible adverse sequelae have not been fully established in children, topiramate may represent an option for infants with high seizure frequency unresponsive to standard antiepileptic drugs.
