Suriclone has a very similar pharmacological profile to the benzodiazepine family of drugs including sedative and anxiolytic properties but with less amnestic effects,[1][2] and its chemical structure is quite different from that of the benzodiazepine drugs.

The mechanism of action by which suriclone produces its sedative and anxiolytic effects is by modulating GABA_A receptors, although suriclone is more subtype-selective than most benzodiazepines.[3]
