Summary

Zolpidem is a sedative-hypnotic drug that is used to treat insomnia. It is a short-term treatment, and should not be used for longer than 10 days. Zolpidem is a preferred treatment for insomnia over benzodiazepines because it does not have as high of a risk for dependence or abuse compared to the benzodiazepine drugs.
