 Etiocholanolone is also known to be an inhibitory androstane neurosteroid, acting as a positive allosteric modulator of the GABAA receptor, and possesses anticonvulsant effects.The unnatural enantiomer of etiocholanolone is more potent as a positive allosteric modulator of GABAA receptors and as an anticonvulsant than the natural form.Etiocholanolone is produced from 5β-dihydrotestosterone, with 3α,5β-androstanediol as an intermediate.
