How Gefitinib 250 mg Tablet Works
Gefitinib works by targeting and inhibiting the epidermal growth factor receptor (EGFR) tyrosine kinase enzyme. This enzyme plays a significant role in the proliferation and survival of cancer cells. By blocking EGFR's activity, Gefitinib disrupts signaling pathways that cancer cells rely on for growth and division, leading to reduced tumor growth and potentially shrinking existing tumors.
This specific mechanism makes Gefitinib 250 mg Tablet effective in tumors with EGFR gene mutations, offering a more focused therapy compared to conventional chemotherapy. The drug selectively affects cancer cells with minimal impact on normal healthy cells.
