Golexanolone, also known by the developmental code name GR-3027, is a neurosteroid medication which is under development for the treatment of hypersomnia and hepatic encephalopathy.[1][2][3][4] It acts as a negative allosteric modulator of the GABAA receptor.[1][2] The medication selectively antagonizes the stimulatory actions of inhibitory neurosteroids like allopregnanolone and tetrahydrodeoxycorticosterone (THDOC) at the GABAA receptor, while not affecting the activation of the GABAA receptor by γ-aminobutyric acid (GABA).[2]
