How does zolpidem work?
Zolpidem belongs to a class of drugs called sedative-hypnotics. It works by enhancing the effect of a neurotransmitter called gamma-aminobutyric acid (GABA) in the brain. GABA is an inhibitory neurotransmitter that reduces nerve activity, leading to calmness and sleep [5].
What is the difference between zolpidem and other sleep medications?
Zolpidem is considered a non-benzodiazepine hypnotic, often referred to as a "Z-drug." While it acts on GABA receptors similarly to benzodiazepines, it has a different chemical structure and may have a slightly different side effect profile and risk of dependence [5]. Other sleep medications include benzodiazepines, antidepressants, and melatonin receptor agonists, each with distinct mechanisms of action and safety profiles.
What are the risks associated with zolpidem use?
Risks include dependence and withdrawal symptoms upon discontinuation, the potential for tolerance where higher doses are needed to achieve the same effect, and the aforementioned complex sleep-related behaviors. It is also associated with a risk of respiratory depression, particularly when combined with other central nervous system depressants [4][5].
