AI summarySynthesized from FDA + DailyMed + ClinicalTrials.gov data
BELSOMRA (suvorexant) is an oral orexin receptor antagonist approved in 2014 for the treatment of insomnia. It works by blocking orexin neuropeptide signaling in the brain, which promotes wakefulness, thereby enabling sleep initiation and maintenance. This novel mechanism differentiates it from traditional sedative-hypnotics and benzodiazepines.
