^NY (what is this?) (verify)

Terbequinil (SR-25776) is a stimulant and nootropic drug which acts as a partial inverse agonist at benzodiazepine sites on the GABA_A receptor. In human trials it was found to partially reverse the sedative and amnestic effects of the hypnotic drug triazolam with only slight effects when administered by itself.^[1]
