Proxibarbal is a barbiturate-class anticonvulsant and sedative-hypnotic that enhances GABA-A receptor-mediated inhibitory neurotransmission by prolonging chloride channel opening time and at higher concentrations directly activating the chloride channel. It was used for the management of epilepsy and as a sedative, though like all barbiturates it carries significant risk of dependence and respiratory depression.
