Zolpidem belongs to a class of medicines that effects the central nervous system, called sedative hypnotics. Zolpidem is closely related to a family of drugs called benzodiazepines. These drugs cause sedation, muscle relaxation, act as anti-convulsants (anti-seizure), and have anti-anxiety properties. Zolpidem has selectivity in that it has little of the muscle relaxant or anti-seizure effect and more of the sedative effect. Therefore, it is used as a medication for sleep.

Zolpidem induces sleep and causes relaxation. It is used to treat sleep disorders such as trouble falling asleep, waking up many times during the night, or waking up too early in the morning.
