Ethotoin is a hydantoin derivative and anticonvulsant. Ethotoin exerts an antiepileptic effect without causing general central nervous system depression. The mechanism of action is probably very similar to that of phenytoin. The latter drug appears to stabilize rather than to raise the normal seizure threshold, and to prevent the spread of seizure activity rather than to abolish the primary focus of seizure discharges. Ethotoin inhibits nerve impulses in the motor cortex by lowering sodium ion influx, limiting tetanic stimulation. Ethotoin is used for the control of tonic-clonic (grand mal) and complex partial (psychomotor) seizures. Ethotoin is marketed as Peganone by Ovation. — NCATS
