Methaqualone acts primarily as a sedative, reducing anxiety and inducing sleep. It binds to GABAA receptors, where it functions as a positive allosteric modulator at many receptor subtypes, enhancing the inhibitory effects of the neurotransmitter GABA. It shows negligible affinity for a wide array of other potential targets, including other receptors and neurotransmitter transporters. This action is similar to that of benzodiazepines like diazepam
