Gefitinib is a receptor tyrosine kinase inhibitor which targets the epidermal growth factor receptor (EGFR) on cells. EGFR is found in large amounts on the surface of some cancer cells, resulting in tumors growing more quickly. Gefitinib blocks the function of EGFR, thus preventing further cancer cell growth and slowing cancer progression.
