GEFISTERIS 250 is a potent medication designed to combat non-small cell lung cancer (NSCLC). It contains Gefitinib (250mg) as its active ingredient, which belongs to a class of drugs known as tyrosine kinase inhibitors. This medication is specifically formulated to target and inhibit the activity of a specific protein involved in the growth and spread of cancer cells, offering a promising treatment option for patients diagnosed with NSCLC.

Key Benefits

• Targeted Therapy: GEFISTERIS 250 offers targeted therapy by specifically inhibiting EGFR tyrosine kinase, leading to the reduction and slowing of cancer cell growth.
• Effective Against NSCLC: This medication is particularly effective for patients with NSCLC, especially those with specific mutations in the EGFR gene.
• Oral Administration: GEFISTERIS 250 is administered orally, providing a convenient and non-invasive treatment option for patients.

How Does It Work?

Gefitinib works by inhibiting the tyrosine kinase activity of the epidermal growth factor receptor (EGFR). EGFR is a transmembrane receptor that, when activated, triggers a cascade of downstream signaling pathways responsible for cell growth, proliferation, and survival. In certain types of cancer, including NSCLC, mutations in the EGFR gene result in uncontrolled cell division and tumor growth. By blocking EGFR, Gefitinib effectively disrupts these signaling pathways, inhibiting the growth and spread of cancer cells.

Directions for Use

• Dosage: The recommended dose of GEFISTERIS 250 is one tablet (250mg) taken once daily, with or without food.
• Administration: Swallow the tablet whole with a glass of water. Do not crush or chew the tablet.
• Consistency: Take the medication at the same time each day to maintain consistent blood levels of the drug.
• Missed Dose: If a dose is missed, take it as soon as you remember. If it is almost time for the next dose, skip the missed dose and resume the regular dosing schedule. Do not double the dose to make up for the missed one.
• Duration: Continue taking GEFISTERIS 250 as prescribed by your healthcare provider, even if you feel well. Do not stop taking the medication without consulting your doctor.

Side Effects

While GEFISTERIS 250 is effective in treating NSCLC, it may cause some side effects. Common side effects include:

• Diarrhea: One of the most common side effects, which can be managed with appropriate hydration and medication.
• Skin Reactions: Rash, dry skin, and itching are common skin-related side effects.
• Nausea and Vomiting: These gastrointestinal symptoms can occur but are usually manageable with anti-nausea medications.
• Fatigue: Feeling tired or weak is a common side effect that can impact daily activities.
• Loss of Appetite: Some patients may experience a reduced desire to eat.
