Ambien, or zolpidem, is a prescription medication commonly used for the treatment of insomnia. This sedative-hypnotic drug works by affecting the gamma-aminobutyric acid (GABA) receptors in the brain, helping to promote relaxation and facilitate sleep onset. While Ambien can be effective for short-term use, it is crucial for patients to follow their healthcare provider's instructions carefully to avoid potential misuse or over-reliance on the medication.
