ORG-21465 is a syntheticneuroactive steroid, withsedative effects resulting from its action as aGABAA receptorpositive allosteric modulator. It is similar to related drugs such asORG-20599, and was similarly developed as an improved alternative to other sedative steroids such asalthesin andallopregnanolone, which despite its superior properties in some respects has not proved to offer enough advantages to be accepted into clinical use.[1][2]
