Can a muscle relaxant keep heavy drinkers calm on breathing machines?
NCT ID NCT02723383
First seen Sep 14, 2026 · Last updated Sep 15, 2026 · Updated 1 time
Summary
Heavy drinkers who need a breathing machine in intensive care often become agitated, which can lead to pulling out tubes, falling, or harming themselves or staff. This Phase 3 trial tests whether baclofen, a drug that calms the nervous system, can prevent these dangerous events better than a placebo. Researchers will enroll 314 adults who drink above recommended limits and are expected to need mechanical ventilation for more than a day. The study measures agitation-related problems, time on the ventilator, length of ICU stay, and sedative and painkiller use.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- baclofen, a muscle relaxant drug also used to reduce alcohol cravings
- What this could lead to
- If baclofen works, intensive care teams could have a routine drug to keep heavily drinking patients calm and safe while they are on breathing machines.
- What could go wrong
- Baclofen can cause sedation and confusion, which may be hard to separate from alcohol withdrawal in very sick patients. The trial may show no benefit, or the results may not apply to lighter drinkers or non-ICU settings.
