Ganaxolone is an orally active analog of allopregnanolone that is not converted to the hormonally active 3-keto form. The enhanced anticonvulsant potency of ganaxolone after neurosteroid withdrawal supports the use of ganaxolone as a specific treatment for perimenstrual catamenial epilepsy._x000D_ Features and Benefits_x000D_ This compound is a featured product for Neuroscience research.
