How Does Zolpidem Work?
Zolpidem belongs to a class of drugs called sedative-hypnotics [2]. It acts on specific receptors in the brain, primarily the GABA-A receptor complex, to enhance the effect of the neurotransmitter GABA (gamma-aminobutyric acid). This enhancement leads to increased inhibitory activity in the central nervous system, promoting sedation and sleep [2].
What Are the Risks Associated with Zolpidem?
Like other sedative-hypnotics, zolpidem carries risks, including the potential for dependence and withdrawal symptoms [1]. It can also cause complex sleep behaviors, such as sleepwalking or sleep-driving, while not fully awake [1]. Patients are advised to take zolpidem only before bed and to ensure they have a full night's sleep before engaging in activities requiring alertness [1].
Can Zolpidem Be Used Long-Term?
Zolpidem is generally recommended for short-term use due to concerns about tolerance, dependence, and potential side effects with prolonged use [1]. If insomnia persists, other treatment strategies should be explored [1].
