The most commonly used drugs are carbamazepine (Calepsin[R]), benzodiazepines (for example, clonazepame [Klonopin[R]]), barbiturates (for example, phenobarbital [Luminal[R]]), primidone (Mysoline[R]), phenytoin (Dilantin[R]),
ethosuximide (Zarontin[R]), gabapentin (Neurontin[R]), tiagabine (Gabitril[R]), topiramate (Topamax[R]), and valproate (Depacon[R]) (Glauser et al., 2006; Ropper & Brown, 2005).
At the time of his admission to the inpatient facility, he was on several medications including valproic acid, clonazepam, felbamate,

Although most of the drugs had no effect or were toxic to the worms, Kornfeld's team found that
ethosuximide, an anticonvulsant drug, increased the worms' life span by 17 percent.
