How Lapatinib works
Lapatinib is an anti-cancer medication. This works against the HER2 (human epidermal growth factor receptor protein) receptors and EGFRs (epidermal growth factor receptor) which are responsible for the over-proliferation of cells. This is how it inhibits the growth of cancerous cells causing downstream signaling pathways.
