Gefitinib is an anti-cancer medication. It works by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps to stop or slow the spread of cancer cells.
It is used in patients in which it has spread to other parts of the body, who have abnormal epidermal growth factor receptor (EGFR) genes, and who have not had previous treatment for cancer.
