|  | Ambien is a prescription short-acting nonbenzodiazepine hypnotic that potentiates gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter, by binding to benzodiazepine type 1 (BZ1) receptors. Ambien is used for the short-term treatment of insomnia. It works quickly (usually within 15 minutes) and has a short half-life (2-3 hours).
