Irinotecan – Topoisomerase I Inhibitor for Colorectal and Lung Cancer
Irinotecan is a prescription chemotherapy drug that belongs to the class of topoisomerase I inhibitors. It is widely used in the treatment of metastatic colorectal cancer, small cell lung cancer (SCLC), and other solid tumors. Irinotecan works by inhibiting the enzyme topoisomerase I, which is essential for DNA replication, leading to DNA damage and cancer cell death.
