Introduction to Dual Orexin Receptor Antagonists
Dual orexin receptor antagonists (DORAs) represent a significant advancement in the treatment of chronic insomnia by targeting the brain's wake-promoting system. Unlike traditional sleep medications that enhance inhibitory neurotransmitters to promote sleep, DORAs work by effectively turning off wakefulness, a breakthrough inspired by the understanding of narcolepsy. This novel approach revolves around the neurotransmitter orexin, which plays a crucial role in regulating wakefulness; a deficiency in orexin is linked to narcolepsy. The latest addition to this family, daridoxorant, offers a promising alternative for patients struggling to achieve restful sleep despite previous treatments.
