Ambien is in a class of drugs known as Sedative-Hypnotics. Ambien works by activating the neurotransmitter GABA, which slows down the brain and the central nervous system (CNS). Ambien is used to treat insomnia but is only intended for short-term use.

How long does it take for Ambien to kick in?

Ambien works relatively quickly, and it remains in the body for a short period of time. It has a rapid onset of action within 30 minutes, with peak effects reached within 1–2.5 hours for most people, depending on whether the person took an immediate- or extended-release version of the drug.

How does Ambien make you sleep?

Zolpidem, commonly known as Ambien, slows down activity in the brain, allowing you to sleep. The immediate release form dissolves right away, helping you fall asleep fast. The extended release version has two layers — the first helps you fall asleep, and the second dissolves slowly to help you stay asleep.
