The cytotoxic effect of oxaliplatin has been correlated with formation of inter- and intrastrand DNA crosslinks that inhibit DNA replication and transcription. Cytotoxicity is cell-cycle nonspecific.
Following a 2-h infusion, C max was 0.814 mcg/mL.
Following a 2-h infusion, Vd is 440 L and approximately 15% of administered platinum is present in the systemic circulation; the remaining 85% is rapidly distributed into tissues and eliminated in the urine. Plasma protein binding (albumin and gamma globulins) is irreversible and greater than 90%. Platinum also binds irreversibly and accumulates approximately 2-fold in erythrocytes.
Rapid and extensive nonenzymatic biotransformation.
Renal excretion is major route of platinum elimination (54% of platinum eliminated in urine; approximately 2% excreted in feces). Plasma Cl is 10 to 17 L/h and correlates with glomerular filtration rate.
Special PopulationsRenal Function Impairment
AUC of platinum increases as renal function decreases: 60% increase with mild (CrCl 50 to 80 mL/min), 140% increase with moderate (CrCl 30 to less than 50 mL/min), and 190% increase with severe (CrCl less than 30 mL/min) renal impairment.Elderly
No effect of age on the ultrafilterable platinum has been observed.Children
Mean C max is 0.75 mcg/mL, AUC 0-48 is 7.52 mcg•h/mL and AUC inf is 8.83 mcg•h/mL at 85 mg/m 2 oxaliplatin. Mean Cl is 4.7 L/h.Gender
There was no significant effect of gender on the Cl of ultrafiltrable platinum.

Dosage and AdministrationAdjuvant Therapy for Stage III Colon Cancer
IV Recommended dose schedule given every 2 wk for 12 cycles (6 mo) according to the following dosing for patients with advanced colorectal cancer.Advanced Colorectal Cancer
Adults Recommended dose schedule given every 2 wk Day 1
IV Oxaliplatin 85 mg/m 2 IV infusion and leucovorin 200 mg/m 2 IV infusion in dextrose 5% in water, both given over 120 min at the same time in separate bags using a Y-line, followed by 5-fluorouracil 400 mg/m 2 IV bolus given over 2 to 4 min, followed by 5-fluorouracil 600 mg/m 2 IV infusion in dextrose 5% in water 500 mL (recommended) as a 22-h continuous infusion.Day 2
IV Leucovorin 200 mg/m 2 IV infusion over 120 min, followed by 5-fluorouracil 400 mg/m 2 IV bolus given over 2 to 4 min, followed by 5-fluorouracil 600 mg/m 2 IV infusion in dextrose 5% in water 500 mL (recommended) as a 22-h continuous infusion. Treatment is recommended until disease progression or unacceptable toxicity.Dose Modification
Prior to subsequent therapy cycles, evaluate patients for clinical toxicities and laboratory tests. Prolongation of infusion time for oxaliplatin from 2 to 6 h may mitigate acute toxicities. The infusion times for infusional 5-fluorouracil and leucovorin do not need to be changed.Dose Modification in Patients With Stage III Colon Cancer
IV Reduce oxaliplatin dose to 75 mg/m 2 in patients who experience persistent grade 2 neurosensory events that do not resolve. Discontinue oxaliplatin in patients who experience persistent grade 3 neurosensory events. The infusional 5-fluorouracil/leucovorin regimen need not be altered. Reduce oxaliplatin dose to 75 mg/m 2 and infusional 5-fluorouracil to 300 mg/m 2 bolus and 500 mg/m 2 22-h infusion for patients after recovery from grade 3/4 GI toxicities, grade 4 neutropenia, or grade 3/4 thrombocytopenia. Delay next dose until neutrophils are 1,500/mm 3 or more and platelets are at least 75,000/mm 3 .Dose Modification in Patients With Advanced Colorectal Cancer
IV Reduce oxaliplatin dose to 65 mg/m 2 in patients who experience persistent grade 2 neurosensory events that do not resolve. Discontinue oxaliplatin in patients who experience persistent grade 3 neurosensory events. The infusional 5-fluorouracil/leucovorin regimen need not be altered. Reduce oxaliplatin dose to 65 mg/m 2 and infusional 5-fluorouracil to 300 mg/m 2 bolus and 500 mg/m 2 22-h infusion for patients after recovery from grade 3/4 GI toxicities, grade 4 neutropenia, or grade 3/4 thrombocytopenia. Delay next dose until neutrophils are 1,500/mm 3 or more and platelets are 75,000/mm 3 or more.
- For IV infusion only. Not for intradermal, subcutaneous, IM, or intra-arterial administration.
- Follow institutional and National Institutes of Health procedures for handling, administration, and disposal of anticancer drugs. Wear appropriate protective equipment when preparing and administering oxaliplatin.
- Use of gloves is recommended. If oxaliplatin solution comes in contact with the skin, wash the skin immediately with soap and water. If oxaliplatin solution contacts a mucous membrane, flush thoroughly with water.
- Dilute prescribed dose of oxaliplatin solution in 250 to 500 mL of dextrose 5% injection.
- Reconstitute oxaliplatin powder with 10 mL (for the 50 mg vial) or 20 mL (for the 100 mg vial) of water for injection or dextrose 5% injection. The reconstituted solution must be further diluted in an infusion solution of 250 to 500 mL of dextrose 5% injection.
- Do not use needles or IV administration sets containing aluminum parts that could come in contact with oxaliplatin during preparation or administration. Aluminum can cause degradation of platinum compounds.
- Do not dilute with sodium chloride injection or other chloride-containing solutions.
- Do not mix with alkaline medications or media (eg, basic solutions of 5-fluorouracil), or administer simultaneously through same infusion line. Flush infusion line with dextrose 5% in water prior to administration of any concomitant medications.
- Do not administer if solution is discolored or cloudy, or if it contains particulate matter.
- Premedicate with antiemetics (eg, 5-HT 3 blockers with or without dexamethasone) as ordered.
Store vials at 59° to 86°F. Do not freeze; protect from light (keep in original outer carton). Solution diluted in dextrose 5% in water is stable for up to 6 h at 68° to 77°F or up to 24 h under refrigeration (36° to 46°F). Protection from light is not required after final dilution.Powder
Store unreconstituted vials at 59° and 86°F. After reconstitution in the original vial, the solution may be stored for up to 24 h at 36° to 46°F. After final dilution with 250 to 500 mL of dextrose 5% injection, the shelf life is 6 h at 68° to 77°F or up to 24 h at 36° to 46°F. Oxaliplatin is not light-sensitive.
Drug InteractionsAnticoagulants (eg, warfarin)
Prolongation of PT and INR has been reported. Monitor coagulation parameters and adjust the anticoagulant dose as needed.5-Fluorouracil
No pharmacokinetic interaction between oxaliplatin 85 mg/m 2 and 5-fluorouracil/leucovorin has been observed in patients treated every 2 wk. Increases of 5-fluorouracil/leucovorin plasma concentrations by approximately 20% have been observed with oxaliplatin 130 mg/m 2 every 3 wk.Nephrotoxic drugs (eg, gentamicin)
Because platinum-containing agents (eg, oxaliplatin) are eliminated primarily through the kidney, Cl of these products may be decreased by coadministration of potentially nephrotoxic compounds. However, this has not been studied.
Adverse reaction are reported for oxaliplatin plus infusional 5-fluorouracil/leucovorin.
