In this article, we will discuss the uses, benefits, side effects and warnings associated with the drug Iressa. Iressa is a prescription medicine used for the treatment of non-small cell lung cancer (NSCLC). It is a type of targeted therapy known as an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI).
Uses
Iressa is prescribed for the treatment of NSCLC in patients whose tumors have specific EGFR mutations. The drug works by inhibiting the activity of the EGFR protein, which leads to the suppression of cancer cell growth and division.
Benefits
The primary benefit of Iressa is that it can effectively treat NSCLC in patients with specific EGFR mutations. Clinical trials have found that Iressa can significantly increase progression-free survival in such patients compared to chemotherapy. The drug can also improve symptoms such as cough, shortness of breath, and chest pain associated with NSCLC.
