Summary

This study tests whether trazodone, a medication often used for depression, can improve sleep in adults aged 65 and older with chronic insomnia. Forty participants will take either trazodone or a placebo for 28 days, then switch after a break. They will track their sleep with diaries and activity monitors to see if the drug reduces insomnia symptoms.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
trazodone
What this could lead to
If it works, this could offer a safe, non-habit-forming sleep aid for older adults with chronic insomnia.
What could go wrong
This is a small, early-phase trial with only 40 participants. The results may not apply to everyone, and trazodone can cause side effects like drowsiness or dizziness.
