TYKERB 250MG is an inhibitor of intracellular tyrosine kinase domains of both HER2 and epidermal growth factor receptor (EGFR).

It passes through the cell membrane and binds to HER2 and EGFR, found inside the cell. Inhibition of HER2 and EGFR receptors by lapatinib, inhibits the HER2-derived tumor cell growth and division, which in turn reduces tumor cell proliferation.
