If approved, suvorexant would be the first in a new class of medicines called orexin receptor antagonists. Orexins are neurotransmitters in the brain that help keep a person awake. By temporarily blocking the actions of orexins, suvorexant helps facilitate sleep. "We are excited about the potential of suvorexant as a new and different approach to treating insomnia, a serious condition that affects up to one-third of the adult population," Darryle Schoepp, Ph.D., said in a press statement. He is senior vice-president and head of the Neuroscience and Ophthalmology Division of Merck Research Laboratories.
