Gefitinib

Gefitinib is a targeted cancer drug used primarily to treat certain types of non-small cell lung cancer. It works by blocking a specific protein called the epidermal growth factor receptor (EGFR) that helps cancer cells grow and divide. By inhibiting this receptor, gefitinib can slow or stop the growth of cancer cells, improving outcomes for some patients. It is often used when other treatments have not been effective and is taken orally in pill form. While it can be effective, it may also cause side effects, so its use is carefully monitored by healthcare providers.
