It is unclear whether this medication has been proven safe or effective for infants under 2 years of age.

Ganaxolone oral suspension comprises ganaxolone, a neuroactive steroid that acts as a positive modulator of the gammaaminobutyric acid A (GABAA) receptor. 1-[(3R, 5S, 8R, 9S, 10S, 13S, 14S, 17S)] ganaxolone 2, 4, 5, 6, 7, 8, 9, 11, 12, 14, 15, 16, 17 tetradecahydrocyclopenta[a]phenanthren-17-yl]ethanone) is a methyl-substituted (at the 3ß position) cyclopenta[a]phenanthren-17-yl]ethanone.

Allopregnanolone, a progesterone derivative, is an analog of the endogenous neurosteroid allopregnanolone. Its empirical formula is C22H36O2, and the molecular weight is 332.53 g/mol


Ganaxolone is a white to off-white crystalline powder that only exists in one crystal form and has low
