Parkinson's drug side effect targeted by antioxidant NAC – but trial stalls

NCT ID NCT03146130

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested whether N-acetylcysteine (NAC), an antioxidant, could help reduce impulse control disorders caused by Parkinson's medications. Only 14 people with mild-to-moderate symptoms were enrolled before the trial was stopped early. The goal was to see if 10 weeks of NAC improved behavior scores compared to a placebo.

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 worked, NAC could offer a way to ease impulse control problems caused by Parkinson's drugs, improving daily life for some patients.
What could go wrong
The trial was terminated early and very small (14 people), so results are not reliable. NAC may not work for this purpose, and side effects are possible.
