General information
Class/mechanism: Irreversible tyrosine kinase inhibitor of EGFR (epidermal growth factor receptor, ErbB1), HER2 (human epidermal growth factor receptor 2, ErbB2), and HER4 (human epidermal growth factor receptor 4, ErbB4). Inhibition of tyrosine kinase autophosphorylation inhibits ErbB signaling.[1][2][3]
