Ambien is a prescription medication primarily used to treat insomnia, a common sleep disorder characterized by difficulty falling asleep, staying asleep, or both. Its active ingredient is zolpidem, which belongs to a class of drugs known as sedative-hypnotics. Here's some detailed information about Ambien:

1. Sleep Initiation: Ambien is particularly effective in helping individuals fall asleep more quickly after going to bed. It works by enhancing the activity of gamma-aminobutyric acid (GABA), a neurotransmitter in the brain that slows down brain activity and promotes relaxation.

2. Short-Term Use: Ambien is typically prescribed for short-term use, usually no longer than 1 to 2 weeks. It's meant to provide temporary relief from insomnia while addressing underlying causes or contributing factors, such as stress, jet lag, or temporary disruptions in sleep patterns.
