Ambien is the brand name for zolpidem, a drug that's used to treat insomnia. Insomnia is a sleep disorder that makes it difficult for you to go to sleep, stay asleep, or both. Ambien is in a class of drugs called sedative-hypnotics. They work by slowing the activity in your brain, which allows for a state of sleep. Sanofi-Aventis makes Ambien, which was approved by the Food and Drug Administration (FDA) in 1992. Several companies make generic zolpidem, which became available in 2007.
Zolpidem comes as a tablet (Ambien) and an extended-release (long-acting) tablet (Ambien CR) to take by mouth. Zolpidem also comes as a sublingual tablet (Edluar, Intermezzo) to place under the tongue and an oral spray (Zolpimist) which is sprayed into the mouth over the tongue.
