What is the difference in how zolpidem and eszopiclone work?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Zolpidem and eszopiclone are prescription sleep medications that both target GABA receptors in the brain, but they work in slightly different ways. Zolpidem (brand name Ambien) primarily helps you fall asleep faster and is typically shorter-acting. Eszopiclone (brand name Lunesta) has a longer half-life, which means it can help you both fall asleep and stay asleep through the night.

If you're struggling with sleep issues, understanding the root cause is the most important first step before considering medication. Insomnia can stem from stress, anxiety, sleep apnea, hormonal changes, or other underlying conditions—each requiring a different approach. Take a free, instant, online symptom check to better understand what may be affecting your sleep and get guidance on the right next steps to take with a healthcare provider.

Explanation

Zolpidem and eszopiclone are both used to help people sleep, but they have some differences in how they work.

Zolpidem

Mechanism: Zolpidem works by enhancing the activity of a neurotransmitter called GABA. This helps slow down brain activity, making it easier to fall asleep.
Use: It is primarily used for short-term treatment of sleep problems, like trouble falling asleep.

Eszopiclone

Mechanism: Similar to zolpidem, eszopiclone also works by affecting GABA. However, it binds to different sites, which might make it work slightly differently.
Use: It is often used for both falling asleep and staying asleep, and can be used for a longer period of time compared to zolpidem.

Both medications help with sleep but are chosen based on specific sleep issues and how long treatment is needed.
