Overview

This drug is a combination chemotherapy regimen consisting of three cytotoxic agents—5-fluorouracil (5-FU), irinotecan, and oxaliplatin. It is used primarily in the treatment of advanced or metastatic colorectal cancer and pancreatic cancer. Each component has a distinct mechanism of action: - 5-fluorouracil is an antimetabolite that inhibits thymidylate synthase, disrupting DNA synthesis. - Irinotecan is a topoisomerase I inhibitor that prevents DNA unwinding and replication. - Oxaliplatin is a platinum-based agent that forms DNA crosslinks, leading to apoptosis. The combination exploits synergistic effects to improve response rates compared to single-agent therapy or two-drug regimens. This regimen can cause significant toxicities including neutropenia, neuropathy (from oxaliplatin), diarrhea (from irinotecan), mucositis, and risk of infusion reactions[1][2][3].
