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.
