It results into an inappropriate activation of an intracellular signal transduction cascade that involves the Ras protein and inhibits apoptosis ultimately leading to uncontrolled proliferation of cell.

Do not start, stop, or change the dosage of any medicine before checking with them first. Gefitinib is a tyrosine kinase inhibitor TKI which reversibly inhibits kinase activity of wild-type and select activation mutations of epidermal growth factor receptor EGFR. EGFR is expressed on cell surfaces of normal and cancer cells and has a role in cell growth and proliferation. Gefitinib prevents autophosphorylation of tyrosine residues associated with the EGFR receptor, which blocks downstream signaling and EGFR-dependent proliferation. Gefitinib has a higher binding affinity for EGFR exon 19 deletion and exon 21 L858R substitution mutation than for wild-type EGFR.
