Oxaliplatin

Oxaliplatin is used with other medications to treat advanced colon or rectal cancer (cancer that begins in the large intestine). Oxaliplatin is also used with other medications to prevent colon cancer from spreading in people who have had surgery to remove the tumor

Oxaliplatin undergoes nonenzymatic conversion in physiologic solutions to active derivatives via displacement of the labile oxalate ligand. Several transient reactive species are formed, including monoaquo and diaquo DACH platinum, which covalently bind with macromolecules. Both inter and intrastrand Pt-DNA crosslinks are formed. Crosslinks are formed between the N7 positions of two adjacent guanines (GG), adjacent adenine-guanines (AG), and guanines separated by an intervening nucleotide (GNG). These crosslinks inhibit DNA replication and transcription. Cytotoxicity is cell-cycle nonspecific.

Diarrhea, changes in taste, mouth sores, nosebleeds, tiredness, headache, dizziness, or trouble sleeping may occur. Nausea and vomiting may be severe in some patients. Your doctor may prescribe medication to prevent or relieve nausea and vomiting, hair loss
