Summary

Researchers at the University of Utah are studying whether propofol, a drug normally used to put people to sleep for surgery, can ease symptoms in adults with treatment-resistant depression. The trial enrolls 32 people aged 18 to 55 who have major depressive disorder or bipolar disorder and have not improved after at least two antidepressant trials. Participants receive a series of six propofol treatments at one of two doses, and researchers track changes in depression scores and brain-related markers.

What this could mean

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

Active substance
propofol, a sedative drug also known as Diprivan
What this could lead to
If propofol eases depression at certain doses, it could offer a new option for people whose depression has not responded to standard medications.
What could go wrong
This is a small early-stage trial of 32 people, so any benefit may not hold up in larger studies. Propofol is a strong sedative given in a clinic, which carries risks like low blood pressure and breathing problems.
