Introduction to Iressa (Gefitinib) 250mg
Geficent (Gefitinib) 250mg is a targeted anticancer medicine used in the treatment of certain types of lung cancer, particularly non-small cell lung cancer (NSCLC). This medicine belongs to a class of targeted therapies that work by blocking specific signals responsible for cancer cell growth.
Geficent (Gefitinib) 250mg is classified under Prescription Medicines, Oncology Medicines, Targeted Cancer Therapy, and Oral Anticancer Drugs. It contains Gefitinib, which works by inhibiting epidermal growth factor receptor (EGFR) activity in cancer cells.
In some markets, Geficent 250mg is available as a local brand containing the same active ingredient Gefitinib, offering a similar therapeutic effect when prescribed by a qualified healthcare professional.
What Is Iressa (Gefitinib)?
Iressa is the original brand name for Gefitinib, an oral targeted therapy widely used in oncology for lung cancer treatment.
Gefitinib belongs to a class of medicines known as Tyrosine Kinase Inhibitors (TKIs). These medicines help block signals that promote cancer cell growth and division.
Generic versions such as Geficent 250mg contain the same active compound and may be used depending on physician recommendation and regional availability.
Drug Class and Mechanism of Action
Gefitinib is classified as a tyrosine kinase inhibitor with strong antineoplastic activity.
How Gefitinib Works
It works in several ways:
- Blocks epidermal growth factor receptor (EGFR) signaling
- Inhibits cancer cell proliferation
- Induces apoptosis (programmed cell death) in cancer cells
Through these mechanisms, Gefitinib helps slow or stop the progression of cancer.
How Iressa Works in the Body
Certain cancer cells depend on EGFR signals to grow and spread. Gefitinib targets and blocks these signals.
Key Actions of Gefitinib
- Stops cancer cell growth signals
- Reduces tumor size and spread
- Helps control disease progression
- Improves survival outcomes in eligible patients
Some generic versions such as Geficent deliver the same active compound, allowing similar targeted cancer treatment when prescribed appropriately.
