Gefitinib Tablets 250 mg – Targeted Therapy for Non-Small Cell Lung Cancer (NSCLC)

Gefitinib Tablets 250 mg are a targeted cancer therapy belonging to a group of drugs known as epidermal growth factor receptor (EGFR) inhibitors. These medications are designed to block the signals that tumors use to grow, divide, and spread.

Gefitinib is most commonly prescribed to treat non-small cell lung cancer (NSCLC) that has EGFR gene mutations. It is typically used as a first-line treatment in adults whose cancer has spread to other parts of the body and whose tumors test positive for EGFR mutations.

Uses of Gefitinib 250 mg Tablets

Gefitinib is indicated for:

• Non-Small Cell Lung Cancer (NSCLC) — in metastatic or advanced stages
• Patients who have EGFR gene mutation-positive tumors
• First-line therapy in place of or after traditional chemotherapy
• Maintenance treatment in some cases

Your oncologist will perform tests to confirm the presence of an EGFR mutation before prescribing Gefitinib.

How Gefitinib Works

Gefitinib is a tyrosine kinase inhibitor (TKI) that specifically targets the EGFR (epidermal growth factor receptor) pathway. In certain cancers like NSCLC, the EGFR gene is mutated, resulting in uncontrolled cell division.

Gefitinib:

• Binds to the ATP-binding site of the EGFR tyrosine kinase
• Inhibits phosphorylation and subsequent signal transduction pathways
• Blocks tumor growth and proliferation
• Slows down spread (metastasis) of cancer cells
• Induces programmed cell death (apoptosis) in cancer cells

It functions as a precision medicine, minimizing damage to surrounding healthy cells compared to conventional chemotherapy.

Gefitinib 250 mg Dosage and Administration

• Typical Adult Dose: 250 mg tablet once daily
• Route: Oral (by mouth)
• Meal Consideration: Can be taken with or without food
• Administration Tip: Take with a full glass of water at the same time daily
• Missed Dose: Skip the missed dose if it’s almost time for your next dose. Do not double up.

Always follow your oncologist’s personalized treatment plan. Dosage may be adjusted if side effects occur or based on liver function.

Benefits of Gefitinib Therapy

• Targets cancer cells with fewer systemic side effects
• Shown to improve progression-free survival in EGFR-positive NSCLC
• Oral tablet form — no hospital infusion required
• Suitable for long-term use with routine monitoring
• High response rate in select patient populations

Side Effects of Gefitinib Tablets

While Gefitinib is generally better tolerated than traditional chemotherapy, it may cause some adverse effects.

Common Side Effects:

• Skin rash or acne
• Diarrhea
• Nail inflammation (paronychia)
• Fatigue
• Loss of appetite
• Dry skin
• Nausea and vomiting
• Eye irritation

Serious Side Effects:

• Interstitial lung disease (rare, but serious)
• Liver toxicity
• Severe diarrhea or dehydration
• Gastrointestinal bleeding
• Abnormal liver tests

Regular blood tests will be conducted to monitor liver function and overall health.

Precautions and Warnings

• Not suitable for patients without EGFR mutation-positive tumors
• Not recommended during pregnancy or breastfeeding
• Use effective contraception during treatment and for at least 2 weeks after the last dose
• Inform your doctor about any lung issues, liver disease, or recent infections
• Gefitinib may impair wound healing. Inform your doctor if you are planning any surgeries
• Ensure you’re monitored for symptoms like sudden shortness of breath or persistent cough

Drug Interactions

Gefitinib interacts with:

• Rifampicin, carbamazepine, and other CYP3A4 inducers (may lower effectiveness)
• Proton pump inhibitors and antacids (reduce Gefitinib absorption)
• Warfarin (increased risk of bleeding)
• Herbal supplements like St. John’s Wort must be avoided

Inform your healthcare provider of all prescription, over-the-counter, or herbal supplements you’re taking.

Storage Instructions

• Store tablets below 30°C (86°F) in a cool, dry place
• Keep in the original blister packaging until use
• Do not store in humid or hot environments
• Keep out of reach of children and pets
