Lunesta is a sedative-hypnotic drug commonly prescribed to treat insomnia. It belongs to a class of medications known as non-benzodiazepine receptor agonists. Lunesta is designed to help people fall asleep more easily and stay asleep.

Mechanism of Action: Lunesta works by affecting certain chemicals in the brain that may be unbalanced in people with insomnia. It enhances the activity of the neurotransmitter GABA (gamma-aminobutyric acid), which has a calming effect on the brain.
