  • Dosing: Recommended dose is 10 mg, no more than once per night taken within 30 minutes of going to bed, with at least 7 hours remaining before the planned time of awakening.
  • Dosage forms: Tablets 5 mg, 10 mg, 15 mg, 20 mg.
  • Adverse events: Tablets 5 mg, 10 mg, 15 mg, 20 mg.
  • Mechanism of action: 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.
