Ambien is a brand name for the medication zolpidem, which is primarily prescribed for the short-term treatment of insomnia. Ambien is FDA-approved for the treatment of insomnia, particularly for helping individuals fall asleep more quickly and stay asleep longer. It is indicated for short-term use, typically for a period of 1 to 2 weeks. Ambien works by enhancing the activity of gamma-aminobutyric acid (GABA), a neurotransmitter that inhibits brain activity, thereby promoting relaxation and inducing sleep.
