title: The multifaceted role of pirfenidone and its novel targets.
abstract: BACKGROUND
  Pirfenidone (PFD) is a molecule that exhibits antifibrotic properties in a variety of in vitro and animal models of lung, liver and renal fibrosis. These pathologies share many fibrogenic pathways with an abnormal fibrous wound-healing process; consequently, tissue repair and tissue regeneration-regulating mechanisms are altered.
  
  
  OBJECTIVE
  To investigate the usefulness of PFD as an antifibrotic agent in clinical and experimental models of fibrotic disease.
  
  
  CONCLUSIONS
  There is a growing understanding of the molecular effects of PFD on the wound healing mechanism, leading to novel approaches for the management of fibrosis in lung, liver and renal tissues. Although the optimum treatment for fibrosis remains undefined, it is possible that combined therapeutic regimens that include this wide-application molecule, pirfenidone, could offer a useful treatment for fibrotic disease.
