Saripidem has a similar pharmacological profile to the benzodiazepine family of drugs including sedative and anxiolytic properties, but its chemical structure is quite different to that of the benzodiazepine drugs, and saripidem is described as a nonbenzodiazepine.

The mechanism of action by which saripidem produces its sedative and anxiolytic effects is by modulating the benzodiazepine binding site on GABA_A receptors, however unlike many older GABA_A agonists, saripidem is highly subtype selective and binds primarily to the ω1 subtype.^[1]
