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.
