Used primarily in the treatment of Dravet syndrome, a severe form of childhood epilepsy. It acts as an anticonvulsant by enhancing the activity of gamma-aminobutyric acid (GABA), the main inhibitory neurotransmitter in the brain. It is typically used in combination with other antiepileptic drugs such as clobazam and valproate to reduce the frequency of seizures. Its application is especially effective in patients who do not respond well to standard therapies. Due to its role in modulating brain activity, it requires careful monitoring for side effects and drug interactions.
