Gefitinib 250 mg is a prescribed drug mainly utilized for treating non-small cell lung cancer (NSCLC). It includes Gefitinib, a targeted treatment belonging to the class of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors. Gefitinib aims to block the activity of the EGFR protein, which is frequently overactive in certain cancer cells, resulting in uncontrolled growth.

This drug is often prescribed for patients with advanced or metastatic NSCLC, particularly those with tumors that have specific EGFR mutations, as they are more likely to respond to treatment.

Mechanism of Action

The active ingredient in Gefitinib, gefitinib, functions by targeting the EGFR, a protein found on cell surfaces that aids in their growth and division. In some cancers, there is either an overexpression or a mutation of EGFR, leading to uncontrolled cell proliferation. Gefitinib inhibits the signals sent by EGFR, which prevents the growth of cancer cells and promotes apoptosis (cell death).

This mechanism, which is aimed at a specific target, reduces the harm done to healthy cells, making it a more accurate treatment than conventional chemotherapy.

Indications

Gefitinib is recommended for:

Initial treatment of patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) and activating EGFR mutations.

Management of patients with EGFR-mutant NSCLC who did not respond to prior chemotherapy.

Note: Before initiating therapy, molecular testing for EGFR mutations is usually conducted to assess whether a patient is likely to benefit from Gefitinib.

Dosage and Administration

Suggested dosage: One tablet (250 mg) per day, regardless of meals.

The tablet must not be crushed or chewed; it should be taken whole with water.

Depending on the individual patient’s response and side effects, it may be necessary to adjust the dose.

To guarantee uniform drug levels in their body, patients are advised to take Gefitinib at the same time every day.

Side Effects

Like all drugs, Gefitinib can lead to side effects. Less serious and frequent side effects include:

Durchfall

Cutaneous rash or desiccation

Vomiting and nausea

Müdigkeit

Appetite loss

Dry eyes or mouth

Side effects that are severe and necessitate immediate medical attention include:

Interstitial lung disease (though uncommon, it can threaten life)

Abnormal liver function

Serious skin reactions

Ocular ailments (like corneal erosion)

Those patients who have severe or persistent symptoms should get in touch with their healthcare provider without delay.

Precautions and Warnings

Before taking Gefitinib, let your doctor know if you:

Are expectant mothers, those preparing for pregnancy, or nursing mothers

Suffer from liver or kidney disease

Suffer from lung issues, particularly interstitial lung disease

Are you using other medications (to prevent drug interactions)

Pregnancy and Breastfeeding: Gefitinib can be harmful to an unborn child, so its use during pregnancy is not advised. Women of childbearing age should employ effective contraceptive methods while undergoing treatment and for some time after the final dose. Due to potential risks to the infant, it is also recommended to avoid breastfeeding while taking Gefitinib.

Drug Interactions

Gefitinib can have interactions with other drugs, which may influence its efficacy or raise the likelihood of side effects. Frequent medication interactions comprise:

Protonenpumpeninhibitoren (z. B. Omeprazol)

Warfarin and additional anticoagulants

Antifungal drugs (such as ketoconazole)

Antikonvulsiva (z. B. Phenytoin, Carbamazepin)

Herbal products such as St. John’s Wort

Always inform your doctor of all the medications and supplements you are taking.

Storage Instructions

Keep at room temperature (15°C to 30°C).

Avoid contact with moisture and direct sunlight.

Make sure children and pets cannot reach it.

Conclusion

Gefitinib 250 mg provides an effective oral treatment option for patients with EGFR-mutant non-small cell lung cancer, featuring a targeted mechanism and manageable adverse effects. It aids in regulating cancer growth and enhancing survival outcomes in qualifying patients by inhibiting the EGFR pathway. Like any cancer treatment, Getinib should be administered under the supervision of an oncologist, with regular monitoring to ensure safety and effectiveness.

It is important to adhere to the doctor’s instructions and attend follow-up appointments in order to monitor the treatment response and manage any side effects.

1. What is the purpose of Gefitinib 250 mg?
Gefitinib in a dosage of 250 mg is mainly prescribed for treating non-small cell lung cancer (NSCLC), especially in patients who have certain EGFR (epidermal growth factor receptor) mutations.

2. What is the mechanism of action of Gefitinib?
Gefitinib works as an inhibitor of tyrosine kinase in EGFR. It prevents signals that promote the growth and division of cancer cells.

3. What is the recommended way to take Gefitinib 250 mg?
It is typically administered orally once a day, regardless of meals. Always follow your doctor’s instructions.

4. Is Gefitinib suitable for all patients with lung cancer?
No. It is most effective for patients with EGFR mutations, which occur more frequently among women, non-smokers, and Asians.

5. For what duration should I take Gefitinib?
The length of time is contingent upon your reaction and the strategy devised by your oncologist. Certain patients continue taking it until the illness advances or adverse effects become intolerable.
