General description

Pirfenidone (5-methyl-1-phenyl-2-[1H]-pyridone) is a synthetic[1] derivative of pyridine.[2]

Application

Pirfenidone has been used:
  • as a post-operative eye drop in rabbits to analyse its antifibrotic effect to improve glaucoma filtration surgery[3]
  • as an anti-scarring agent to examine whether it affects the foreign body reaction after glaucoma drainage device (GDD) implantation in a rabbit[2]
  • to test its antifibrotic potential in primary cultures of human orbital fibroblasts (hOFs)[4]
  • as tumor necrosis factor (TNFα) inhibitor to study its effect in hypoxia[5]

Biochem/physiol Actions

Inhibits collagen production and fibroblast proliferation.
Pirfenidone inhibits collagen production and fibroblast proliferation. It has shown antifibrotic and anti-inflammatory properties in variety of animal models of pulmonary fibrosis, and in clinical trials.
Pirfenidone is used to treat idiopathic pulmonary fibrosis (IPF). It helps to decrease the weakening of lung function decline and ameliorate progression-free survival.[6] Pirfenidone can repress the multiplication and contraction of collagen of human tenon′s fibroblasts.[2]
