The active ingredient, zolpidem, acts on the neurotransmitter GABA (gamma-aminobutyric acid), enhancing its inhibitory effects. This results in a calming effect on the brain, promoting relaxation and making it easier for individuals to fall asleep. Ambien is particularly effective in initiating sleep and sustaining a full night's rest. Typically prescribed in a 10mg dosage, Ambien is designed for short-term use due to its potential for dependence and tolerance. Patients are advised to take it just before bedtime, ensuring they have a full 7-8 hours available for sleep to avoid morning drowsiness.
