Tagrisso 80 mg (Osimertinib) is a third-generation EGFR tyrosine kinase inhibitor designed for the treatment of non-small cell lung cancer (NSCLC) with specific EGFR mutations. It works by irreversibly blocking mutant EGFR proteins, inhibiting cancer cell growth while sparing normal cells.

This pharmaceutical-grade tablet is suitable for physician-supervised targeted therapy in advanced or metastatic NSCLC.
