N-Acetylcysteine in Ischemic Stroke: A Systematic Review

This 2026 systematic review investigates whether N-acetylcysteine (NAC) can serve as an effective neuroprotective treatment for patients suffering from ischemic stroke. By analyzing several clinical trials, the authors explore how the drug’s antioxidant and anti-inflammatory properties might mitigate brain damage during the critical hours following a blockage. While initial data suggests NAC may improve neurological scores and stabilize certain biochemical markers, the overall findings remain inconclusive due to small sample sizes and inconsistent results across studies. The researchers conclude that while the medication appears safe and biologically promising, its status as a standard clinical therapy is not yet supported. Consequently, the paper calls for larger, more rigorous trials to determine the optimal dosing and timing required to protect the brain effectively alongside existing reperfusion therapies.
