Could a simple inhaler prevent deadly pneumonia in ventilator patients?
NCT ID NCT07409727
First seen Jun 27, 2026 · Last updated Jul 10, 2026 · Updated 1 time
Summary
This study tests whether inhaling a medicine called N-acetylcysteine (NAC) can prevent pneumonia in critically ill patients who need a breathing machine. About 80 adults on ventilators will receive either NAC or a placebo. Researchers will track how many develop pneumonia and how long it takes, along with other breathing and infection measures.
