How does zolpidem work?
Zolpidem is a nonbenzodiazepine hypnotic that acts on the central nervous system. It is believed to exert its effects by binding to specific sites on GABA-A receptors, which are thought to be part of the benzodiazepine receptor complex. This binding enhances the inhibitory effects of gamma-aminobutyric acid (GABA), a neurotransmitter that reduces neuronal excitability, leading to sedation [3].
