Application

Ethosuximide has been used:
  • to confirm its effect on spike wave discharges (SWD) in rats
  • to examine its effects on spontaneous locomotion and anxiety-related thigmotaxis behaviours in zebrafish larvae of wild type
  • as a model drug for the treatment of epilepsy in vivo(4)

Biochem/physiol Actions

Ethosuximide is an anticonvulsant drug and an antagonist for T-type calcium channel. It is known to prevent spike wave discharges, characterized in absence seizures.

Generalized absence seizures are characterized by bilateral spike-wave discharges (SWDs), particularly in the frontoparietal cortical region. In WAG/Rij and GAERS rats with absence epilepsy, recent evidence indicates that SWDs arise first from the lateral somatosensory cortex (LSC), that is, the
