💊 Gefitinib Tablets – A Targeted Therapy for Lung Cancer
🧬 Introduction
Gefitinib tablets are a breakthrough in targeted cancer therapy, especially for patients with specific genetic mutations in lung cancer. Unlike traditional chemotherapy, Gefitinib works at the molecular level to stop cancer growth with fewer systemic side effects.
Gefitinib is widely known under the brand name Iressa, and is used globally in oncology treatment protocols.
🫁 What Are Gefitinib Tablets?
Gefitinib is an EGFR (Epidermal Growth Factor Receptor) inhibitor, used primarily in the treatment of:
- Non-small cell lung cancer (NSCLC)
- Advanced or metastatic lung cancer
- EGFR mutation-positive cancer cases
It belongs to a class of targeted therapies that block signals responsible for tumor growth.
⚙️ How Gefitinib Works
Gefitinib targets the Epidermal Growth Factor Receptor, a protein found on the surface of some cancer cells.
👉 It works by:
- Blocking EGFR signaling pathways
- Preventing cancer cell growth and division
- Slowing or stopping tumor progression
This makes it highly effective in patients with EGFR gene mutations.
🏥 Medical Uses
Gefitinib tablets are prescribed for:
- First-line treatment of EGFR-positive NSCLC
- Patients who cannot tolerate chemotherapy
- Advanced-stage lung cancer cases
👉 It is often recommended after genetic testing confirms EGFR mutation.
💊 Dosage & Administration
- Standard dose: 250 mg once daily
- Taken orally with or without food
- Should be taken at the same time every day
⚠️ Always follow an oncologist’s prescription.
⚠️ Side Effects
Like all cancer medicines, Gefitinib may cause side effects:
Common:
- Skin rash
- Diarrhea
- Dry skin
- Loss of appetite
Serious (rare):
- Lung inflammation (interstitial lung disease)
- Liver toxicity
👉 Regular monitoring is required during treatment.
