NCIt definition : An anilinoquinazoline with antineoplastic activity. Gefitinib inhibits the catalytic
activity of numerous tyrosine kinases including the epidermal growth factor receptor
(EGFR), which may result in inhibition of tyrosine kinase-dependent tumor growth.
Specifically, this agent competes with the binding of ATP to the tyrosine kinase domain
of EGFR, thereby inhibiting receptor autophosphorylation and resulting in inhibition
of signal transduction. Gefitinib may also induce cell cycle arrest and inhibit angiogenesis.

Alternative definition : NCI-GLOSS: A drug that is used to treat certain types of non-small cell lung cancer
and is being studied in the treatment of other types of cancer. It is a type of epidermal
growth factor receptor (EGFR) tyrosine kinase inhibitor.;
