What is Ambien and How Does It Work?

Ambien is the brand name for zolpidem tartrate, a sedative-hypnotic medication classified as a Schedule IV controlled substance. It belongs to a class of medications called non-benzodiazepine hypnotics, sometimes referred to as “Z-drugs” . These drugs work by interacting with the gamma-aminobutyric acid (GABA) receptor complex in the brain, enhancing the inhibitory effects of GABA, which slows brain activity and promotes sleep .

Available Formulations

Ambien is available in several formulations:

Important: The 5 mg and 10 mg tablets are not scored and should be swallowed whole .
