Doctors at OHSU
Doernbecher Children's Hospital have claimed that ethosuximide, one of the
oldest available anti-seizure medications, is the most effective treatment for
childhood absence epilepsy.
The experts reported the finding in this week's New England
Journal of Medicine . To come up with
the conclusion, the study group compared three medications typically used to
treat the most common childhood epilepsy syndrome, childhood absence epilepsy,
which is characterized by frequent non-convulsive seizures that cause the child
to stop what he or she is doing and stare for up to 30 seconds at time.
Prior to this study, there was no definitive evidence on which drug worked best.
"Much of our scientific understanding of childhood epilepsy care today comes
from historical experience or studies involving adult patients with related, but
not identical, conditions," explained Colin Roberts, MD, OHSU Doernbecher's
principal investigator for the study, assistant professor of pediatrics and
neurology, and director of OHSU Doernbecher's Pediatric Epilepsy Program,
"This study is an important milestone in our understanding of childhood absence
epilepsy. Never before have we been able to document in such a comprehensive,
scientific fashion the best options to treat children with this condition."
The study group enrolled 453 children newly diagnosed with childhood absence
epilepsy from July 2004 to October 2007. Study participants were randomly
assigned to ethosuximide, valproic acid or lamotrigine. Drug doses were
incrementally increased until the child was seizure-free. After 16 weeks of
therapy, the researchers found.
Ethosuximide and valproic acid were significantly more effective than
lamotrigine in controlling seizures, with no intolerable side effects. They also
determined ethosuximide was associated with significantly fewer negative effects
on attention.
