How does lapatinib work
Lapatinib inhibits the tyrosine kinase activity associated with two oncogenes, EGFR (epidermal growth factor receptor) and HER2/neu (human EGFR type 2). Over expression of HER2/neu can be responsible for certain types of high-risk breast cancers in women. Like sorafenib, lapatinib is a protein kinase inhibitor shown to decrease tumor-causing breast cancer stem cells. WebHow does Tykerb work? About: Lapatinib (Tykerb®) By blocking a particular enzyme from working, this medication can slow the growth of cancer cells. Lapatinib works to inhibit the function of two types of tyrosine kinases: epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor (HER-2).
