    Depressant

    Summary PsychonautWiki

    Nitromethaqualone is a central nervous system (CNS) depressant of the quinazolinone class that acts as a sedative and hypnotic. Nitromethaqualone is a derivative of methaqualone, distinguished by the presence of a nitro group, which affects its pharmacological profile. While methaqualone gained popularity in the 1960s and 70s, nitromethaqualone has been studied less extensively but exhibits similar depressant effects.
