Here, we explored the therapeutic effect of gefitinib, a specific inhibitor of EGFR, on the development and progression of peritoneal fibrosis in a rat model. Daily intraperitoneal injections of chlorhexidine gluconate induced peritoneal fibrosis, indicated by thickening of the submesothelial area with an accumulation of collagen fibrils and activation of myofibroblasts, accompanied by time-dependent phosphorylation of EGFR. Administration of gefitinib immediately after injury prevented the onset of peritoneal fibrosis and delayed administration after the onset of peritoneal fibrosis halted fibrosis progression. Gefitinib treatment abrogated the increased phosphorylation of EGFR, Smad3, signal transducer and activator of transcription 3, and NF-\n                    <jats:italic toggle=\"yes\">\u03ba<\/jats:italic>\n                    B during peritoneal fibrosis; it also inhibited the accompanying overproduction of TGF-\n                    <jats:italic toggle=\"yes\">\u03b2<\/jats:italic>\n                    1 and proinflammatory cytokines and the infiltration of macrophages to the injured peritoneum.
