Ambien, also known by its generic name zolpidem, is a prescription medication primarily used to treat insomnia, a common sleep disorder characterized by difficulty falling asleep or staying asleep. Here are the primary uses of Ambien:

1. Insomnia Treatment: Ambien is primarily prescribed to help people with insomnia fall asleep more quickly and stay asleep throughout the night. It belongs to a class of medications called sedative-hypnotics, which work by enhancing the effects of the neurotransmitter gamma-aminobutyric acid (GABA) in the brain. This helps to calm the brain activity, promoting relaxation and sleep.

2. Short-term Management: Ambien is typically recommended for short-term use, usually for no longer than two to four weeks. Prolonged use may lead to tolerance, dependence, and rebound insomnia when the medication is stopped.
