Suvorexant: A Dual Orexin Receptor Antagonist for Treating Sleep Disturbance in Posttraumatic Stress

NCT03642028

This study is recruiting at 4 US sites in 3 states, according to its ClinicalTrials.gov record last updated .

Summary

Post-traumatic stress disorder (PTSD) is a common consequence of combat that can result in trauma-related hyperarousal and sleep disturbances. Poor sleep, one of the most common complaints in Veterans with PTSD, can be distressing, impair concentration and memory, and contribute to physical health conditions, such as metabolic syndrome, inflammation, and cardiovascular disease. The orexin neuropeptide system underlies both sleep and stress reactivity. Suvorexant, a drug that reduces orexin, improves sleep in civilians, but has not yet been tested in Veterans with PTSD.
