AI summarySynthesized from FDA + DailyMed + ClinicalTrials.gov data
IRESSA (gefitinib) is an oral tyrosine kinase inhibitor that targets the epidermal growth factor receptor (EGFR), used primarily in non-small cell lung cancer (NSCLC) with EGFR mutations. It works by blocking intracellular signaling pathways that drive tumor cell proliferation. Gefitinib was a landmark agent in precision oncology when approved in 2003.
