The U.S. Food and Drug Administration  approved Belsomra (suvorexant) tablets for use as needed to treat difficulty in falling and staying asleep (insomnia).

Belsomra is an orexin receptor antagonist and is the first approved drug of this type. Orexins are chemicals that are involved in regulating the sleep-wake cycle and play a role in keeping people awake. Belsomra alters the signaling (action) of orexin in the brain.
