Transforming Growth Factor Inhibitors

Reduction of fibroblast proliferation may decrease the formation and/or accumulation of fibrotic materials within the lungs.

Pirfenidone (Esbriet)

The precise mechanism by which pirfenidone may work in pulmonary fibrosis has not been established. It inhibits transforming growth factor (TGF)-beta, a chemical mediator that controls many cell functions including proliferation and differentiation. It also inhibits the synthesis of TNF-alpha, a cytokine that is known to have an active role in inflammation.
