Gefitinib is used as a type of cancer treatment that targets a protein known as epidermal growth factor receptor (EGFR). It works by inhibiting or blocking EGFR to control the growth of cancer cells. Gefitinib is particularly used in the treatment of lung cancer and is prescribed by an oncologist or cancer specialist. It comes in tablet form and is taken orally. The usage is determined based on the patient’s medical history, type of cancer, and stage. Side effects may occur during the use of Gefitinib, and each patient may have different reactions. Therefore, it is important to carefully follow the advice and instructions of your doctor during the use of the medication.
What is Gefitinib Used For?
Gefitinib is used in the treatment of patients with a type of lung cancer called non-small cell lung cancer (NSCLC), particularly those with specific mutations in the epidermal growth factor receptor gene. Gefitinib can be effective in patients with EGFR mutations and is often preferred for their treatment. By acting on the EGFR protein, Gefitinib attempts to control the growth and division of cancer cells. It can stop or slow down the growth of cancer cells in patients who respond to the treatment.
