Could a few doses of ketamine help both depression and alcohol addiction?
NCT ID NCT06090422
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study investigates whether ketamine, given as four intravenous infusions over two weeks, can reduce depression and alcohol cravings in adults who have both conditions. Participants are already in inpatient addiction therapy and are randomly assigned to receive either ketamine or a low-dose sedative (midazolam) as a comparison. The trial tracks changes in depression severity and alcohol craving over six months to see if ketamine offers added benefit beyond standard care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Ketamine hydrochloride
- What this could lead to
- If successful, this could point toward a new treatment approach for people struggling with both depression and alcohol use disorder.
- What could go wrong
- This is an early-phase trial with only 34 participants, so results may not apply to everyone. Ketamine can cause side effects like dissociation and blood pressure changes.
