The aetiopathogenesis and effective treatments for CP\/CPPS are needed to be untangled. Pirfenidone is a molecule that exhibits anti\u2010inflammatory, antifibrotic, and antioxidative stress capacities in a variety of animal experiments and clinical trials. This study was aimed to investigate the therapeutic effect of pirfenidone on CP\/CPPS and to identify the mechanism responsible for it.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A CP\/CPPS model was induced in rats by intraprostatic injection of complete Freund's adjuvant (CFA). Blood and prostatic tissues were harvested for assessment after the administration of pirfenidone or vehicle for 4 weeks.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The findings revealed that pirfenidone significantly ameliorated chronic pelvic pain and inhibited prostatic inflammation and fibrosis. Further study found that pirfenidone suppressed the expression of proinflammatory mediators, including tumor necrosis factor\u2010\u03b1, interleukin\u20101\u03b2 (IL\u20101\u03b2), IL\u20106, IL\u20108. Pirfenidone exhibited a potent antioxidant capacity through improving the activities of glutathione, catalase, total superoxide dismutase, and reducing the production of malondialdehyde. Furthermore, pirfenidone also facilitated the polarization of M2 macrophages and suppressed the activation of the nuclear factor\u2010\u03baB (NF\u2010\u03baB) signaling pathway.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Pirfenidone can exert a beneficial effect against CFA\u2010induced CP\/CPPS by anti\u2010inflammatory, antioxidative, antifibrotic properties, and the function is mediated at least partly through the M2 polarization of macrophages and the inhibition of NF\u2010\u03baB signaling pathway. These findings suggest that pirfenidone holds promise as a potential therapeutic for the treatment of CP\/CPPS.<\/jats:p><\/jats:sec>","DOI":"10.1002\/pros.23995","type":"journal-article","created":{"date-parts":[[2020,6,22]],"date-time":"2020-06-22T17:18:48Z","timestamp":1592846328000},"page":"917-925","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["The
