Summary

This study tested whether N-Acetylcysteine (NAC), an antioxidant, could help people with severe COVID-19 lung failure in the ICU. 59 adults received either NAC or a placebo alongside standard care. Researchers measured changes in inflammation markers and tracked survival and length of ICU stay.

What this could mean

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

Active substance
N-Acetylcysteine (NAC)
What this could lead to
If it works, NAC could become a cheap, widely available add-on treatment to reduce inflammation and improve survival in severe COVID-19 lung injury.
What could go wrong
This is a small, completed trial with only 59 participants. Results may not apply to all patients, and NAC's benefits are uncertain until larger studies confirm them.
