Zolpidem

Zolpidem (sold under the brand names Ambien, Ambien CR, Stilnox, and Sublinox) is a prescription medication used for the treatment of insomnia, as well as some brain disorders. It is a short-acting nonbenzodiazepine hypnotic of the imidazopyridine class that potentiates gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter, by binding to GABA_A receptors at the same location as benzodiazepines. It works quickly (usually within 15 minutes) and has a short half-life (two to three hours).
