NAC (N-acetylcysteine) and chronic bronchitis

NAC (N-acetylcysteine) has long been used for chronic bronchitis. A study published in 2000, for example, surveyed 9 well-designed trials of NAC for broncopulmonary conditions and found evidence that “a prolonged course of oral NAC prevents acute exacerbations of chronic bronchitis” –meaning improved quality of daily life for patients.
