Gefitinib

Gefitinib is a targeted cancer therapy used primarily to treat non-small cell lung cancer (NSCLC). It belongs to a class of drugs called tyrosine kinase inhibitors (TKIs) and works by blocking the activity of a specific protein (EGFR) that promotes cancer cell growth. Gefitinib is prescribed for patients whose tumors have certain mutations in the EGFR gene.

Uses of Gefitinib

• Treatment of advanced or metastatic non-small cell lung cancer (NSCLC)
• Used in patients with EGFR mutation-positive tumors
• Helps shrink tumors and slow cancer progression

How Gefitinib Works

Gefitinib blocks the epidermal growth factor receptor (EGFR), which is involved in the growth and spread of cancer cells. By inhibiting EGFR, it prevents tumor growth and promotes cancer cell death.

Benefits of Gefitinib

• Effective in EGFR-positive NSCLC cases
• Targets cancer cells specifically, sparing healthy cells
• Oral administration for ease of use
• Delays disease progression
• Improves quality of life in advanced cancer patients
