Suvorexant is a selective dual antagonist of orexin receptors OX1R and OX2R. It has been approved for the treatment of insomnia. The mechanism by which suvorexant exerts its therapeutic effect in insomnia is presumed to be through antagonism of orexin receptors. The orexin neuropeptide signaling system is a central promoter of wakefulness. Blocking the binding of wake-promoting neuropeptides orexin A and orexin B to receptors OX1R and OX2R is thought to suppress wake drive. — NCATS
