This answer focuses on benefits, uncertainty, and practical interpretation. - Beyond established risk factors such as smoking and exposure to pollutants increasing evidence emphasizes the role of oxidative stress (OS) in COPD pathophysiology. [López-Denis M (2026); evidence level 1] - N-acetylcysteine-based interventions were associated with a significant reduction in exacerbation risk (risk ratio 0.80; 95% confidence interval 0.66-0.98), corresponding to a 20% relative reduction. [López-Denis M (2026); evidence level 1] - Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide. [López-Denis M (2026); evidence level 1] - This document consolidates existing evidence to this effect, and adds insights from practicing clinicians to guide about use of NAC in clinical practice. [Barne M (2026); evidence level 2] - Conclusion This consensus underscores the role of NAC in chronic respiratory diseases beyond its mucolytic properties and reiterates that NAC's antioxidant, anti-inflammatory, immunomodulatory and anti-biofilm properties provide significant clinical utility. [Barne M (2026); evidence level 2] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational.
