Pirfenidone 400mg (Pirfenex)

Pirfenex 400mg contains Pirfenidone 400mg, an oral antifibrotic medication used primarily in the treatment of idiopathic pulmonary fibrosis (IPF). Pirfenidone has anti inflammatory and antifibrotic properties and is used to help slow the decline of lung function associated with IPF.

Pirfenidone works through multiple biological pathways involved in inflammation and fibrosis. While its precise mechanism is not completely understood, it can reduce processes associated with the formation and progression of scar tissue in the lungs.

Pirfenex 400mg should be taken exactly as directed by a qualified healthcare professional. Treatment commonly involves gradual dose escalation to improve tolerability, and liver function testing is recommended before and during treatment.
