Irinotecan

Irinotecan is a chemotherapy medication primarily used in the treatment of colorectal cancer and other solid tumors. It belongs to a class of drugs known as topoisomerase I inhibitors, which work by interfering with the DNA replication process in cancer cells, thereby preventing their growth and multiplication. Irinotecan is often used in combination with other cancer medications and is administered under the supervision of a healthcare professional. It is typically given through intravenous infusion and plays a vital role in advanced or metastatic cancer treatment regimens.

Uses of Irinotecan

• Treatment of metastatic colorectal cancer
• Used in combination chemotherapy regimens (e.g., FOLFIRI)
• Effective in certain types of lung and gastric cancers
• Part of second-line therapy in advanced cancers

How Irinotecan Works

Irinotecan works by inhibiting topoisomerase I, an enzyme required for DNA replication. This prevents cancer cells from multiplying, leading to their death and a reduction in tumor size.
