Official title
Effect of a Dual Orexin Receptor Antagonist, Lemborexant, on Total Sleep Time in Shift Workers: a Randomized Controlled Trial
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Insomnia and daytime sleepiness are common complaints among night shift workers, but effective sleep treatments in shift workers are lacking. The aim of this Phase IV double-blind, placebo-controlled, randomized study is to test whether a dual orexin antagonist, Lemborexant (5mg or 10mg), which would be expected to block the clock-driven orexin-mediated wakefulness during the day, will increase daytime sleep time in shift workers who complain of difficulty sleeping during the daytime compared to placebo.
