Observational Study Evaluating Lemborexant for Insomnia in Adults With Psychiatric Disorders

What this Trial Is About

Researchers are evaluating the effectiveness and safety of lemborexant, a new dual orexin receptor antagonist, in treating adults with mental disorders complicated by insomnia. This observational study focuses on patients aged 18 and above who meet the DSM-5 criteria for mental disorders and have an Insomnia Severity Index score of 11 or higher. The study aims to provide real-world evidence for optimizing treatment plans for insomnia alongside psychiatric conditions. Participants will receive lemborexant tablets taken orally before bedtime, starting at 5 mg per day, which may be increased to 10 mg based on clinical response and tolerance. The treatment period lasts 8 weeks, including a baseline assessment week and 8 weeks of active treatment. Patients who are using benzodiazepine receptor agonists at the start are recommended to gradually reduce and stop these within the first 4 weeks. The study is single-arm and prospective, with all participants receiving lemborexant. During the study, participants will complete various assessments including the Insomnia Severity Index, Sleep Satisfaction VAS, and Epworth Sleepiness Scale at baseline, week 4, and week 8. Researchers will monitor changes in insomnia symptoms, treatment retention, benzodiazepine discontinuation rates, dose adjustments, and adverse events. The total duration of participation is approximately 8 weeks, with follow-up to observe symptom improvement and safety outcomes.
