Neuroactive steroid, methyl analogue of allopregnanolone, that positively and allosterically modulates GABAA receptors; anticonvulsant effect thought to result from tonic modulation of GABA-mediated inhibition. Precise mechanism in CDD seizures is unknown.
成人の通常用量(添付文書の要約)
Adults: treatment initiation is not recommended; efficacy and safety not established. Treatment may be continued into adulthood in adolescents with demonstrated benefit.

注意が必要な方
- Causes somnolence and sedation; other CNS depressants (anti-seizure drugs, opioids, antidepressants, alcohol) may potentiate this.
- Suicidal behaviour and ideation reported with antiepileptic drugs; caregivers should monitor and seek medical advice if signs emerge.
- Avoid strong CYP3A4 inducers (carbamazepine, phenobarbital, phenytoin, primidone, rifampicin, St John's Wort) as they reduce ganaxolone exposure.
