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 GABAA receptors, although suriclone is more subtype-selective than most benzodiazepines.[3]
