Studies suggest that N-acetylcysteine (NAC) potentially reduces inflammation and hyperinflation in patients with COPD.
In this pilot study the efficacy, safety and tolerability of high dose NAC in 12 patients with moderate COPD will be examined. These patients will receive a placebo for 12 weeks and NAC for 12 weeks in a dosage of 3 times 600 mg a day on top of their usual medication in a randomized crossover design. All subjects will be followed for 28 weeks.
The effect of high dose NAC on small airways will be assessed by measuring the total and peripheral airway resistance calculated with Computational Fluid Dynamics (CFD). The effect on oxidative stress will be assessed by measuring exhaled NO and specific markers (CRP, erythrocyte sedimentation rate, IL-6, 8-isoprostane, H2O2, TNF-alfa, glutathione, GPX, SOD and IL-8) in blood and Exhaled Breath Condensate (EBC). Dynamic and static lung volumes will be assessed by spirometry, body plethysmography and diffusion. Quality of life and symptoms will be assessed by the St George Respiratory Questionnaire.

The N-acetyl derivative of CYSTEINE. It is used as a mucolytic agent to reduce the viscosity of mucous secretions. It has also been shown to have antiviral effects in patients with HIV due to inhibition of viral stimulation by reactive oxygen intermediates.
An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.

COPD (chronic obstructive pulmonary disease)
COPD (chronic obstructive pulmonary disease) is used for a number of conditions including chronic bronchitis and emphysema, which all lead to the airways in the lungs becoming damaged and thus narrower, making inhalation and exhalation harder...
