Zaleplon is a medication primarily used to treat insomnia, helping individuals fall asleep more quickly. It belongs to a class of drugs known as non-benzodiazepine sedative-hypnotics, which work by affecting certain chemicals in the brain that may be unbalanced in people with sleep problems. Typically taken shortly before bedtime, zaleplon has a rapid onset of action, allowing for a quick transition to sleep. Its effects are relatively short-lived, making it less likely to cause next-day drowsiness compared to other sleep medications. However, it is important to use it under a doctor's guidance to avoid potential side effects or dependency.
