💡

Lifestyle & Tips

  • Avoid exposure to cold temperatures, cold drinks, and cold objects, especially during and for a few days after infusion, as this can worsen nerve pain (neuropathy). Wear warm clothing, gloves, and scarves.
  • Stay well-hydrated by drinking plenty of fluids unless otherwise instructed by your doctor.
  • Practice good oral hygiene to prevent mouth sores (mucositis).
  • Report any signs of infection (fever, chills) immediately, as your immune system may be weakened.
  • Avoid activities that could lead to cuts or bruises due to potential for low platelet counts.
  • Discuss any new or worsening numbness, tingling, or pain in your hands or feet with your healthcare team.
  • Use effective contraception during treatment and for at least 9 months after the last dose for women, and for at least 6 months after the last dose for men, as oxaliplatin can harm a developing baby.

Pharmacology

🔬

Mechanism of Action

Oxaliplatin is a platinum-based antineoplastic agent. It forms DNA adducts (inter- and intra-strand crosslinks) by binding to guanine and adenine residues. This inhibits DNA replication and transcription, leading to cell cycle arrest and apoptosis. It is cell cycle non-specific.
📊

Pharmacokinetics

Absorption:

Bioavailability: 100% (IV administration)
Tmax: End of infusion (for ultrafilterable platinum)
FoodEffect: Not applicable (IV administration)

Distribution:

Vd: Not precisely determined due to extensive and irreversible binding to tissues and red blood cells. Initial distribution phase is rapid.
ProteinBinding: >90% (of platinum in plasma, primarily to albumin and gamma globulins)
CnssPenetration: Limited (low penetration into CSF)

Elimination:

HalfLife: Initial distribution half-life: 0.4-14 hours (for ultrafilterable platinum); Terminal elimination half-life: ~391 hours (reflects platinum bound to tissues and red blood cells)
Clearance: Renal clearance is the primary route for ultrafilterable platinum.
ExcretionRoute: Primarily renal (50% of platinum excreted renally within 48 hours), some fecal excretion.
Unchanged: <1% (of parent drug)
⏱️

Pharmacodynamics

OnsetOfAction: Rapid (cytotoxic effects begin shortly after exposure)
PeakEffect: Not directly measurable in terms of clinical effect; related to cumulative dose and duration of exposure.
DurationOfAction: Effects persist due to irreversible DNA binding and long tissue retention of platinum. Clinical response is cumulative over cycles.

Safety & Warnings

⚠️

BLACK BOX WARNING

Anaphylactic-like reactions to oxaliplatin have been reported and may occur within minutes of administration. Epinephrine, corticosteroids, and antihistamines have been required to treat these reactions. Patients should be observed for signs of anaphylaxis during and after oxaliplatin infusion. Peripheral sensory neuropathy is a common adverse reaction. Acute symptoms include transient paresthesia, dysesthesia, and hypesthesia, often exacerbated by cold exposure. Chronic symptoms include persistent paresthesia, dysesthesia, and hypesthesia, which may be associated with functional impairment. Myelosuppression (neutropenia, thrombocytopenia, and anemia) is common and dose-limiting. Monitor complete blood counts prior to each cycle and adjust dose as appropriate.

Special Patient Groups

🤰

Pregnancy

Oxaliplatin can cause fetal harm when administered to a pregnant woman. It is classified as Pregnancy Category D. Advise pregnant women of the potential risk to the fetus. Women of childbearing potential should be advised to use effective contraception during treatment and for at least 9 months after the last dose. Men with female partners of childbearing potential should use effective contraception during treatment and for at least 6 months after the last dose.

Trimester-Specific Risks:

First Trimester: High risk of major birth defects and miscarriage due to rapid cell division and organogenesis.
Second Trimester: Risk of fetal growth restriction, myelosuppression, and other developmental abnormalities.
Third Trimester: Risk of fetal myelosuppression, growth restriction, and potential for premature birth.
🤱

Lactation

It is not known whether oxaliplatin is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in breastfed infants, breastfeeding is contraindicated during oxaliplatin therapy and for at least 3 months after the last dose.

Infant Risk: L5 (Contraindicated) - High risk of serious adverse effects to the infant, including myelosuppression and other toxicities.
👶

Pediatric Use

The safety and effectiveness of oxaliplatin in pediatric patients have not been established. Limited data suggest that oxaliplatin is not effective in pediatric solid tumors and may cause significant toxicity. Use is generally not recommended outside of specific clinical trials.

👴

Geriatric Use

No overall differences in effectiveness were observed between elderly and younger patients. However, elderly patients (≥65 years) may be more susceptible to certain toxicities, particularly myelosuppression (neutropenia, thrombocytopenia) and peripheral neuropathy. Close monitoring for adverse reactions and appropriate dose modifications are recommended.

Clinical Information

💎

Clinical Pearls

  • Oxaliplatin is unique among platinum agents for its characteristic acute peripheral neuropathy, often triggered or exacerbated by cold exposure (cold dysesthesia). Advise patients to avoid cold food/drinks and wear warm clothing.
  • Pre-medication with antiemetics (e.g., 5-HT3 antagonists, dexamethasone) is crucial to manage nausea and vomiting, which can be severe.
  • Hypersensitivity reactions can occur, often after several cycles. Patients should be monitored closely during and after infusion. Emergency equipment should be readily available.
  • Cumulative peripheral neuropathy is a dose-limiting toxicity. Regular neurological assessments are essential, and dose modifications or discontinuation may be necessary to prevent irreversible damage.
  • Oxaliplatin does not cause significant nephrotoxicity like cisplatin, but renal function should still be monitored, and dose adjustments are needed for moderate to severe renal impairment.
  • Unlike cisplatin, oxaliplatin does not typically cause significant ototoxicity or alopecia.
🔄

Alternative Therapies

  • Cisplatin (another platinum analog, different toxicity profile)
  • Carboplatin (another platinum analog, different toxicity profile, primarily myelosuppression)
  • Irinotecan (topoisomerase I inhibitor)
  • 5-Fluorouracil (5-FU) (antimetabolite)
  • Capecitabine (oral fluoropyrimidine)
  • Targeted therapies (e.g., Bevacizumab, Cetuximab, Panitumumab, Regorafenib, Trifluridine/Tipiracil) for colorectal cancer, often used in combination with or after chemotherapy.
