At a glance
Oxaliplatin is a platinum-based anticancer drug used for colon and rectal cancer. It binds to cancer cell DNA to inhibit cell growth and division.
Indications
- Adjuvant treatment of stage III colon cancer (after complete resection of primary tumor)
- Treatment of advanced colorectal cancer
Pharmacology
Oxaliplatin undergoes nonenzymatic conversion to active derivatives via displacement of oxalate ligand. Active derivatives form inter- and intrastrand Pt-DNA crosslinks (GG, AG, GNG) which inhibit DNA replication and transcription, causing cell death.
Dosage

- Day 1: Oxaliplatin 85 mg/m² + Leucovorin 200 mg/m² (2 hr IV), then 5-FU 400 mg/m² IV bolus (2-4 min), then 5-FU 600 mg/m² IV infusion (22 hr)
- Day 2: Same regimen WITHOUT oxaliplatin
- Repeat every 2 weeks; Adjuvant: 12 cycles (6 months)
