Indications & Clinical Uses

Irinotecan is employed in the management of colorectal cancer, targeting tumor cells through inhibition of DNA replication.

  • Metastatic colorectal cancer: improves survival as part of combination chemotherapy regimens.
  • Adjuvant therapy for colon cancer: reduces risk of disease recurrence after surgical resection.
  • Locally advanced colorectal cancer: used in neoadjuvant regimens to shrink tumors before surgery.

How It Works

  • Irinotecan is a prodrug that is converted intracellularly to SN‑38, a potent inhibitor of topoisomerase I. By stabilizing the DNA‑topoisomerase I complex, it prevents relegation of single‑strand DNA breaks, leading to accumulation of DNA damage and ultimately cell death in rapidly dividing tumor cells.

Side Effects

Irinotecan may cause a range of adverse reactions, varying in frequency and severity.

Common Side Effects

  • Diarrhea: often severe and may require antidiarrheal therapy.
  • Nausea: may be accompanied by vomiting.
  • Neutropenia: reduced white blood cell count increasing infection risk.
  • Alopecia: hair loss during treatment.

Serious or Rare Side Effects

  • Severe neutropenic infection: febrile neutropenia requiring hospitalization.
  • Acute cholinergic syndrome: abdominal cramps, sweating, and bradycardia.
  • Hypersensitivity reactions: rash, dyspnea, or anaphylaxis.

Precautions & Warnings

Before initiating therapy, clinicians should assess patient-specific risk factors and monitor for toxicity.

  • Monitor blood counts: regular CBC to detect neutropenia.
  • Assess liver function: dose adjustments may be needed for hepatic impairment.
  • Evaluate renal function: consider renal status before administration.
  • Avoid in pregnancy: contraindicated due to fetal risk; use effective contraception.
  • Use anti‑diarrheal prophylaxis: loperamide may be prescribed to manage early diarrhea.
  • Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Avoid Interactions

Irinotecan interacts with several drug classes that can alter its efficacy or safety profile.

Major Interactions (Avoid)

  • Strong CYP3A4 inducers (e.g., rifampin): may reduce irinotecan exposure.
  • UGT1A1 inhibitors (e.g., atazanavir): can increase risk of severe neutropenia and diarrhea.

Moderate Interactions (Monitor Closely)

  • Anticoagulants (warfarin): increased bleeding risk, monitor INR.
  • Other myelosuppressive agents: additive bone marrow suppression.
  • Anticholinergic drugs: may exacerbate cholinergic syndrome.

Frequently Asked Questions

Irinotecan Accord is indicated for the treatment of metastatic colorectal cancer and as adjuvant therapy following surgical resection of colon cancer. It is administered as part of combination chemotherapy protocols to improve survival and reduce disease recurrence in adult patients.

Irinotecan is a prodrug that is metabolized to SN‑38, which inhibits topoisomerase I. This inhibition prevents the re‑ligation of single‑strand DNA breaks during replication, leading to accumulation of DNA damage and ultimately causing death of rapidly dividing cancer cells.

The dosing regimen for Irinotecan Accord is individualized. The prescribing oncologist determines the dose, schedule, and combination with other agents based on the patient’s clinical condition, body surface area, and treatment goals.

Irinotecan is classified as Pregnancy Category D, indicating evidence of fetal risk. It should not be used during pregnancy, and breastfeeding is contraindicated because the drug can be excreted in milk and may harm the infant.

To place an order, submit an enquiry on the Irinotecan Accord product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies, and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details (including cold‑chain if needed), and import documentation.

Compared with other colorectal‑cancer agents such as oxaliplatin or 5‑fluorouracil, Irinotecan offers a distinct mechanism by targeting topoisomerase I. It is often combined with fluoropyrimidines to enhance efficacy, but it may have a higher incidence of severe diarrhea and neutropenia, requiring careful monitoring.

Irinotecan Accord should be stored refrigerated at 2‑8 °C. Keep the solution in its original container, protect it from light, and avoid freezing or shaking. If the product must be transported, maintain the cold‑chain throughout the distribution process.

Irinotecan Accord is given as an intravenous infusion by a qualified healthcare professional. The infusion rate and duration are determined by the prescribing physician and are typically administered in a clinical setting equipped for monitoring infusion‑related reactions.

The most critical risks include severe neutropenia leading to infection, life‑threatening diarrhea, acute cholinergic syndrome, and rare hypersensitivity reactions. Patients should be monitored closely for signs of infection, gastrointestinal toxicity, and any allergic symptoms throughout treatment.

Irinotecan Accord is contraindicated in patients who are pregnant, breastfeeding, or have known hypersensitivity to irinotecan or its excipients. Caution is also advised for individuals with severe hepatic impairment, uncontrolled infections, or pre‑existing severe bone‑marrow suppression.
