Biochem/physiol Actions
Ganaxolone (3alpha-hydroxy-3beta-methyl-5alpha-pregnane-20-one) is a positive allosteric modulator of the GABAA receptor subtype; synthetic analog of the endogenous neurosteroid allopregnanolone; effective against chemically induced seizures in rats and mice. 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.
