It is an antifibrotic agent with anti-inflammatory and antioxidant properties that is used to treat idiopathic pulmonary fibrosis (IPF), which is a chronic, progressive form of interstitial pneumonia. While its mechanism of action is not yet fully understood, pirfenidone is proposed to primarily regulate tumor necrosis factor (TNF) pathways and modulate cellular oxidation. The FDA first approved pirfenidone alongside [nintedanib] as one of the first drugs to treat IPF."}]
