WHAT IS GEFTINAT ?
Gefitinib belongs to a group of anti-cancer medicines known as tyrosine kinase inhibitors (TKI). These medicines work by blocking chemical messengers (called tyrosine kinases) which send signals to cells to grow. Geftinat stops cancer cells from growing and spreading.
Geftinat is consumed for the treatment of Non small cell lung cancer that has spread into surrounding tissues (locally advanced cancer) or to other parts of the body in people with certain types of tumors. In order for Gefitinib to work, the cancer cells need to have receptors for a protein called Epidermal Growth Factor (EGFR).
