What this trial studies

This clinical trial investigates the effectiveness of lemborexant, an orexin receptor antagonist, in improving sleep quality among hospital rotating shift workers who experience sleep problems. Participants aged 20-60 years with a history of sleep issues related to their work schedule will be enrolled and randomly assigned to receive either lemborexant or a placebo. The study aims to assess changes in sleep efficiency, quality of life, and related symptoms over the course of the trial. By focusing on a specific population that faces unique sleep challenges, this trial seeks to provide valuable insights into the management of sleep disorders in shift workers.

Who should consider this trial

Good fit: Ideal candidates are hospital rotating shift workers aged 20-60 who have been experiencing sleep problems for at least three months.

Not a fit: Patients with untreated mental health conditions, obstructive sleep apnea, or those currently undergoing medication adjustments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved sleep quality and overall well-being for hospital shift workers.

How similar studies have performed: Other studies have explored the use of orexin receptor antagonists for sleep disorders, indicating potential for success in this approach.
