Cinnamic acid mitigates methotrexate-induced lung fibrosis in rats: comparative study with pirfenidone.

Purpose: Lung fibrosis is a heterogeneous lung condition characterized by excessive accumulation of scarred tissue, leading to lung architecture destruction and restricted ventilation. The current work was conducted to examine the probable shielding influence of cinnamic acid against lung fibrosis induced by methotrexate.
