General description

A competitive blocker of benzodiazepine activation of inhibitory GABAergic synpases (ID50 = 200 µg/kg/i.p). Binds to the benzodiazepine site of GABAA receptors. Enhances GABAA-receptor mediated currents and antagonizes the enhancing effects of benzodiapine agonist flurazepam. Exhibits fast association and dissociation from the benzodiazepine binding site. Permeates the blood brain barrier, however, the level of uptake may depend on efflux effects of p-glycogprotein transporter.
