Gefitinib Tablets 250mg in Pakistan

Gefitinib Tablets 250?mg are a prescription anticancer medication classified in a group of targeted therapies known as tyrosine kinase inhibitors (TKIs). These tablets are specifically indicated for the treatment of advanced or metastatic non?small cell lung cancer (NSCLC) in adult patients whose tumors have identifiable EGFR (epidermal growth factor receptor) mutations.

Scientific Mechanism: How Gefitinib Works

Gefitinib belongs to the class of medicines called EGFR tyrosine kinase inhibitors (EGFR?TKIs). The epidermal growth factor receptor (EGFR) is a protein found on the surface of certain cells, including many lung cancer cells. It plays a critical role in cell growth and survival.

Primary Clinical Uses and Indications

Advanced or Metastatic Non?Small Cell Lung Cancer (NSCLC)

Gefitinib is most effective in patients whose tumors show activating EGFR mutations (e.g., exon 19 deletions, exon 21 L858R substitution). In these patients, EGFR signaling is a principal driver of cancer growth.

First?Line Targeted Therapy

In eligible patients, Gefitinib can be used as first?line treatment, often in place of standard chemotherapy, offering disease control with a potentially more tolerable side effect profile.

After Failure of Prior Chemotherapy

Gefitinib may also be used when other chemotherapy options have failed or are not suitable based on patient condition and oncologist judgment.

Patient selection for Gefitinib typically requires genetic testing for EGFR mutations to confirm likelihood of response. Patients without such mutations generally do not benefit from this targeted therapy.

Standard Dosage and Administration

The common dose of Gefitinib for adult patients with EGFR?positive NSCLC is:

250?mg taken orally once daily, at approximately the same time each day.

Additional administration details:

• Tablets may be taken with or without food.

• Usually continued daily until disease progression or until the oncologist advises otherwise.

• Swallow the tablet whole — do not crush, break, or chew.

Storage and Handling

Proper storage helps maintain medication integrity:

Store Gefitinib Tablets in a cool, dry place, away from direct sunlight.
Keep out of reach of children and pets.
Do not use tablets past their expiry date.

Packaging & Availability in Pakistan

Gefitinib tablets in Pakistan are typically supplied in:

• 30 tablets per pack — common oncology packaging.
• Packaged under brand or generic names such as Gefitinib IP, Geftinat, Gefticip, or imported versions.
• Prescription required — sold only through licensed pharmacies with an oncologist’s script.

Frequently Asked Questions (FAQs)

Q: Is Gefitinib a chemotherapy drug?
A: Technically no — Gefitinib is a targeted therapy (EGFR?TKI), distinct from traditional cytotoxic chemotherapy, used specifically in EGFR?mutated lung cancers.

Q: Do I need a genetic test before Gefitinib?
A: Yes — EGFR mutation testing is recommended to determine eligibility and potential benefit.

Q: How long should treatment continue?
A: Treatment may continue daily as long as the patient benefits and side effects are manageable — this is decided by the treating oncologist.

Q: Can it be taken with food?
A: Yes — Gefitinib can be taken with or without food as directed.
