What is it about?
We compared the eff i c acy of p irfenidone plus inhaled N acetylcysteine with results for pirfenidone alone for idiopathic pulmonary fibrosis . Combination treatment with inhaled N acetylcysteine and pirfenidone is likely to result in worse outcomes for IPF .

Why is it important?
The efficacy and tolerability of combination therapy with an antifibrotic agent and inhaled N-acetylcysteine are unclear. This study th erefore compared the efficacy and safety of combination treatment with pirfenidone and inhaled N-acetylcysteine 352.4mg twice daily with the results for pirfenidone alone for treatment of IPF over a 48 week treatment period
Perspectives
The present results indicate that inhaled N acetylcysteine, as administered in this trial, should not be used to treat IPF. Present and previous results indicate that we should not use off-label N acetylcysteine or conduct a new clinical trial without genetic analysis before patient selection.
