Mechanism of action

Erlotinib selectively inhibits the intracellular tyrosine kinase domain of EGFR, a receptor frequently overexpressed or mutated in various cancers. By blocking EGFR autophosphorylation, it disrupts downstream signaling pathways (MAPK and PI3K/AKT) that drive cell proliferation, survival, and angiogenesis. This mechanism is particularly effective in tumors with EGFR mutations or high EGFR expression.
