Summary

This trial investigates if a drug can reduce insomnia in pre-diabetic midlife women.

Who is the study for?
This trial is for midlife women aged 40-65 who are pre-diabetic, experiencing insomnia and hot flashes, including at night. They should have an Insomnia Severity Index score of ≥15. Women must be postmenopausal or late perimenopausal without serious mental health issues, major organ disease, recent surgery, or use of sleep medications.
What is being tested?
The study tests if Suvorexant can improve sleep in women with pre-diabetes and insomnia compared to a placebo (a pill with no active drug). Participants will not know which treatment they receive to ensure the results are unbiased.
What are the potential side effects?
Suvorexant may cause drowsiness during the day, headaches, dizziness, abnormal dreams or nightmares. It might also lead to complex sleep behaviors like sleepwalking which could increase the risk of injury.
