Afatinib
Afatinib
Afatinib (pronounced as /əˈfætɪnɪb/) is a type of medication used in the treatment of certain types of cancer, specifically non-small cell lung cancer (NSCLC) and, in some cases, breast cancer. It belongs to a class of drugs known as tyrosine kinase inhibitors.
Etymology
The name "Afatinib" is derived from the Latin word "affinis", meaning "related to", and the suffix "-ib", which is commonly used in the names of tyrosine kinase inhibitors.
Usage
Afatinib works by blocking the action of a certain naturally occurring substance that may be needed to help cancer cells multiply. It is used when the cancer has spread to other parts of the body (metastasized), or cannot be removed by surgery, and the patient has certain "EGFR" gene mutations.
