Β Ambien, the brand name for zolpidem, is a prescription medication primarily used to treat insomnia, a sleep disorder characterized by difficulty falling asleep or staying asleep. As a non-benzodiazepine sedative-hypnotic, Ambien works by enhancing the effects of gamma-aminobutyric acid (GABA), a neurotransmitter that inhibits brain activity, leading to sedative and hypnotic effects. This mechanism helps initiate sleep and improve sleep maintenance, facilitating a more restful and uninterrupted sleep cycle.Β Β
