Ambien (zolpidem) is a prescription medication primarily used for the short-term treatment of insomnia. It belongs to the sedative-hypnotic class, working by enhancing GABA activity in the brain, which promotes relaxation and sleep. Ambien is effective in helping individuals fall asleep quickly but is not intended for long-term use. Misuse or prolonged use can lead to dependence, memory issues, and withdrawal symptoms upon discontinuation.
