Gefitinib is a synthetic anilinoquinazoline which inhibits the intracellular phosphorylation of numerous tyrosine kinases associated w/ transmembrane cell surface receptors found on both normal and cancer cells, including epidermal growth factor receptor (EGFR) tyrosine kinase. Tyrosine kinase activity appears to be essentially important to cell proliferation and survival.

Concomitant use w/ CYP3A4 inducers (e.g. rifampicin, phenytoin, carbamazepine, barbiturates) may reduce serum gefitinib levels. Plasma concentrations may be increased w/ potent CYP3A4 inhibitors (e.g. itraconazole, ketoconazole). Increased INR or bleeding events w/ warfarin. May increase plasma levels of metoprolol. May exacerbate vinorelbine-induced neutropenia. Decreased plasma levels and potential reduction in efficacy w/ drugs that affect gastric pH (e.g. PPIs, H2-receptor antagonists).
