Afatinib 40 mg – First-Line Targeted Therapy for EGFR-Positive Lung Cancer

Afatinib 40 mg is an oral targeted cancer treatment used for advanced non-small cell lung cancer (NSCLC) in patients with EGFR (epidermal growth factor receptor) mutations. It is a tyrosine kinase inhibitor (TKI) that helps stop the growth and spread of cancer cells by targeting and blocking EGFR and related pathways.

Prescribed as a first-line treatment, Afatinib offers greater precision than chemotherapy by selectively attacking cancer-driving mutations, often resulting in better progression-free survival for patients with specific genetic profiles.

How Afatinib 40 mg Works & Why It’s Effective

Afatinib irreversibly binds to EGFR and other HER family receptors (HER2 and HER4), blocking the signals these proteins send to cancer cells to grow and divide. This targeted approach helps to minimize the growth of tumor cells while preserving healthy cells to a greater extent than conventional treatments.

Key Benefits:

• First-line treatment for EGFR mutation-positive NSCLC
• Oral dosing—no need for IV administration
• Blocks EGFR, HER2, and HER4 to stop cancer growth
• Delays tumor progression and improves quality of life
• Effective in tumors resistant to older EGFR inhibitors

Afatinib 40 mg is the standard starting dose for most adults unless a lower dose is recommended due to side effects or specific health concerns.

Dosage, Safety, and Side Effects

Standard Dosage:

• 40 mg once daily on an empty stomach (1 hour before or 2 hours after meals).
