Erlotinib

Erlotinib is a medication primarily used to treat certain types of lung cancer and pancreatic cancer. It works by blocking a protein called EGFR (epidermal growth factor receptor) that helps cancer cells grow and divide. By inhibiting this protein, Erlotinib can slow down the progression of the cancer or sometimes shrink tumors. It's typically prescribed for patients whose cancers have specific genetic changes that make them more likely to respond to this treatment. Like all medications, Erlotinib may have side effects, and its use is determined by a healthcare professional based on individual patient factors.
