Buy Ambien Online, known by its generic name zolpidem, is a prescription medication primarily used for the short-term treatment of insomnia, a condition characterized by difficulty falling asleep, staying asleep, or experiencing restorative rest. Belonging to a class of medications called sedative-hypnotics, Ambien works on the brain by enhancing the activity of a neurotransmitter called gamma-aminobutyric acid (GABA). By increasing GABA activity, Ambien slows brain activity and promotes relaxation, which makes it easier for individuals to fall asleep.
