Erlotinib is a medication used in the treatment of certain types of cancer, including non-small cell lung cancer and pancreatic cancer. It belongs to a class of drugs known as tyrosine kinase inhibitors.

Erlotinib works by inhibiting the activity of a specific protein called the epidermal growth factor receptor (EGFR). This protein is involved in the growth and spread of cancer cells. By blocking EGFR, erlotinib helps to slow down or stop the growth of cancer cells and shrink tumors.

The medication is typically taken orally in the form of tablets. The dosage and treatment duration depend on the specific type and stage of cancer being treated, as well as the individual’s overall health.

Common side effects of erlotinib may include rash, diarrhea, nausea, and fatigue. More serious side effects, such as liver problems or lung toxicity, can occur but are less common. Regular monitoring of liver function and lung function may be recommended during treatment.

Erlotinib should only be used under the guidance and prescription of a qualified healthcare professional experienced in the treatment of cancer. It may interact with other medications, so it is important to inform the healthcare provider about all medications being taken, including over-the-counter drugs and supplements.

In summary, erlotinib is a medication used in the treatment of certain types of cancer. It inhibits the epidermal growth factor receptor to slow down cancer cell growth. Regular monitoring and adherence to healthcare provider instructions are important during erlotinib treatment.
