Ambien is a brand name for zolpidem tartrate, a sedative-hypnotic medication prescribed for the short-term treatment of insomnia [1]. The generic form of Ambien is simply zolpidem tartrate [2].
What is Zolpidem Tartrate Used For?
Zolpidem tartrate is primarily used to help people fall asleep [1]. It works by slowing down activity in the brain, which can lead to drowsiness and the ability to fall asleep [1]. It is typically prescribed for individuals experiencing difficulty initiating sleep [1].
How Does Generic Zolpidem Work?
Zolpidem tartrate belongs to a class of drugs called sedative-hypnotics [1]. It acts on the central nervous system, specifically by enhancing the effect of a neurotransmitter called GABA (gamma-aminobutyric acid) [3]. GABA is an inhibitory neurotransmitter, meaning it reduces nerve activity. By increasing GABA's effects, zolpidem calms brain activity, promoting relaxation and sleep [3].
When Does the Patent for Ambien Expire?

What are the Differences Between Brand-Name Ambien and Generic Zolpidem?
The primary difference between brand-name Ambien and generic zolpidem tartrate is the inactive ingredients [5]. Both contain the same active ingredient, zolpidem tartrate, in the same dosage [5]. The inactive ingredients, such as fillers, binders, and dyes, may vary between brands and generics. Regulatory agencies like the U.S. Food and Drug Administration (FDA) require generic drugs to be bioequivalent to their brand-name counterparts, meaning they perform the same way in the body [5].
What Are the Potential Side Effects of Zolpidem Tartrate?
Common side effects of zolpidem tartrate can include drowsiness, dizziness, lightheadedness, and a "drugged" feeling [1]. More serious side effects, though less common, can involve unusual behavior, memory problems, hallucinations, and signs of an allergic reaction [1]. It is important to take zolpidem tartrate exactly as prescribed and to avoid activities requiring alertness until the medication's effects have worn off [1].
