Generic Chlorambucil Information

Introduction

Chlorambucil is an oral alkylating agent belonging to the nitrogen‑mustard class of chemotherapy drugs. It is primarily prescribed for certain types of blood cancers and is listed under the therapeutic group “Cancer.” In Hong Kong, chlorambucil is accessed through specialist oncology clinics and, when a prescription is presented, can be dispensed by licensed pharmacies. For patients who encounter limited local supply or high out‑of‑pocket costs, a verified generic version offers a cost‑effective alternative.

What is Chlorambucil?

Chlorambucil is the generic version of the brand name Leukeran (also marketed historically as Mytac in some regions). Both contain the identical active compound chlorambucil, a synthetic derivative of nitrogen mustard. The drug was first synthesized in the 195s and received approval for clinical use in the early 196s. It is manufactured by several multinational pharmaceutical companies; in North America and Europe, major producers include Mallinckrodt and Bristol‑Myers Squibb, while in Asia, licensed manufacturers such as Hikma and Cipla supply the generic formulation. Our online pharmacy provides this generic alternative as a cost‑effective treatment option for eligible patients in Hong Kong.

How Chlorambucil Works

Chlorambucil enters cells and undergoes spontaneous cyclization to form an aziridinium ion, a highly reactive electrophile. This ion alkylates nucleophilic sites on DNA, most notably the N7 position of guanine bases. The resulting DNA cross‑links interfere with the double‑helix structure, preventing strand separation during replication and transcription. Because rapidly dividing malignant cells rely on uninterrupted DNA synthesis, chlorambucil preferentially induces apoptosis in those cells while having a slower effect on normal tissues.

Pharmacokinetically, chlorambucil is absorbed after oral ingestion, reaching peak plasma concentrations within 2–4 hours. It is metabolised hepatically to inactive pyridyl‑acetic acid derivatives and is excreted primarily via the kidneys (≈ 60 % unchanged). The drug’s half‑life ranges from 1 to 2 hours, but its cytotoxic impact persists because DNA adducts are not rapidly repaired.

Conditions Treated with Chlorambucil

• Chronic Lymphocytic Leukemia (CLL) – The most common indication; chlorambucil remains a first‑line or maintenance option, especially for elderly or frail patients who may not tolerate aggressive regimens.
• Waldenström Macroglobulinemia – Used alone or in combination with rituximab for disease control.
• Hairy Cell Leukemia (in selected cases) – Alternative when purine analogues are contraindicated.
• Low‑grade Non‑Hodgkin Lymphoma – Occasionally prescribed for indolent subtypes where disease burden is low.

In Hong Kong, hematologic malignancies account for approximately 6 % of all cancer cases, with CLL representing the majority of adult leukemias. The local oncology community follows international guidelines (e.g., NCCN, ESMO) that list chlorambucil as an evidence‑based option for patients who require oral, less intensive therapy.

Patient Groups Most Likely to Benefit

• Older adults (≥ 65 years) – Reduced renal clearance and comorbidities often limit the use of intensive intravenous chemotherapy; chlorambucil’s oral route and moderate potency make it suitable.
• Patients with limited performance status (ECOG ≥ 2) – The drug’s tolerable side‑effect profile permits continuation of therapy without frequent hospital visits.
• Individuals requiring long‑term maintenance therapy – Chronic low‑dose chlorambucil can sustain remission in CLL after initial induction.
• Patients with contraindications to monoclonal antibodies or novel agents – Those with severe hypersensitivity or financial constraints may opt for chlorambucil as a monotherapy.

Conversely, chlorambucil is generally not appropriate for:

• Young patients needing curative intent with high‑risk disease (more aggressive regimens are preferred).
• Individuals with severe hepatic impairment (metabolism may be compromised).
• Pregnant or breastfeeding women (classified as Category D – evidence of fetal risk).

Risks, Side Effects, and Interactions

Common

• Myelosuppression – Neutropenia, anemia, and thrombocytopenia are dose‑dependent; routine blood counts are mandatory.
• Gastrointestinal disturbances – Nausea, mild vomiting, and loss of appetite occur in up to 30 % of patients.
• Dermatologic reactions – Alopecia, mild rash, and photosensitivity are frequently reported.

Rare

• Secondary malignancies – Long‑term exposure has been associated with an increased risk of therapy‑related acute leukemia and solid tumors; incidence remains low (< 1 %).
• Pulmonary toxicity – Interstitial pneumonitis has been documented rarely and requires immediate drug discontinuation.

Serious

• Severe neutropenia with infection – Febrile neutropenia is a medical emergency; hospitalization for intravenous antibiotics may be required.
• Hepatotoxicity – Elevated transaminases and rare cases of hepatic failure have been reported; liver function monitoring is advised.
• Hypersensitivity reactions – Anaphylaxis, though extremely uncommon, mandates immediate cessation of therapy.

Drug–Drug Interactions

• Other myelosuppressive agents (e.g., cyclophosphamide, methotrexate) – additive bone‑marrow toxicity.
• Anticoagulants (warfarin, direct oral anticoagulants) – chlorambucil may potentiate bleeding risk through platelet suppression.
• Vaccines – Live attenuated vaccines should be avoided during treatment due to immunosuppression.

Patients should provide a complete medication list, including over‑the‑counter products and traditional Chinese medicines, to their oncology team.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing – For CLL, the typical regimen is .5 mg/kg per day (maximum 10 mg) taken orally for 7 days each month, or an alternatively low‑dose schedule of 2 mg daily for 3 months followed by a maintenance dose of .5 mg/kg every 2–3 months. Dosage adjustments are required for renal impairment (creatinine clearance < 30 mL/min).
• Administration – Swallow tablets whole with a glass of water; food may be taken concurrently to minimise nausea.
• Missed dose – If a dose is missed within 12 hours, take it as soon as remembered. If more than 12 hours have elapsed, skip the missed dose and resume the regular schedule. Do not double‑dose.
• Overdose – Symptoms may include severe nausea, vomiting, diarrhoea, and profound bone‑marrow suppression. Seek immediate medical attention; supportive care with intravenous fluids, anti‑emetics, and possible growth‑factor support (eCSF) is standard.

Precautions – Avoid alcohol during therapy because it can exacerbate bone‑marrow toxicity. Patients with active infections should defer treatment until resolved. Regular monitoring includes complete blood counts every 2–4 weeks and liver/kidney function tests at baseline and periodically thereafter.
