So, afatinib is this special kind of medicine that stops EGFR and HER2 kinases from doing their thing. It’s like a traffic cop for these receptors. They use afatinib to help treat a type of lung cancer called NSCLC, especially when there are certain changes in the EGFR gene.
How it works is by blocking this EGFR signaling pathway, which is like a secret pathway that tells cancer cells to grow and spread. You can get afatinib in three strengths: 20, 30, and 40 milligrams, and they come as these coated tablets. The doc usually says to take 40 milligrams a day, on an empty stomach if you can.
Each pack usually has 30 tablets. You can take this med whenever you want, just don’t chug grapefruit juice with it.
