Ambien is the brand name for zolpidem, a prescription medication primarily used for the short-term treatment of insomnia, particularly difficulties with sleep initiation. Classified as a non-benzodiazepine sedative-hypnotic, Ambien works by affecting specific neurotransmitter receptors in the brain that help induce sleep. Although it produces effects similar to benzodiazepines, it is chemically distinct, which gives it a unique profile regarding effectiveness, safety, and potential side effects.
