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.
Ambien works by activating the neurotransmitter GABA and binding it to the GABA receptors in the same location as the benzodiazepines such as Xanax and Valium. The extra GABA activity triggered by the drug inhibits the neuron activity that is associated with insomnia. In other words, it slows down the brain. Ambien is extremely effective at initiating sleep, usually working within 20 minutes. It does not, however, have an effect on sustaining sleep unless it is taken in the controlled release form.
