Alkacel
Alkacel
- In our pharmacy, Alkacel requires a valid prescription and can be purchased in India or through select international distributors. Delivery available within 5–14 days with discreet packaging.
- Alkacel is used to treat multiple myeloma, ovarian carcinoma, neuroblastoma, malignant melanoma, and as a bone marrow transplant conditioner. It works as an alkylating agent that damages cancer cell DNA to inhibit tumor growth.
- Usual doses vary: For multiple myeloma, 16 mg/m² intravenously every 2 weeks for initial treatment, then monthly. For ovarian carcinoma, 0.2 mg/kg daily for 5 days every 4–6 weeks.
- Administered intravenously as a reconstituted solution from lyophilized powder in a vial.
- Onset of cellular action occurs within minutes after IV administration due to rapid distribution.
- Duration extends through treatment cycles (weeks to months) due to irreversible DNA damage, despite a plasma half-life of ~1.5 hours.
- Avoid alcohol completely during treatment, as it amplifies gastrointestinal toxicity and liver strain.
- Most common side effects include leukopenia, severe nausea/vomiting, diarrhea, and thrombocytopenia (increased infection/bleeding risk).

Alkacel contains melphalan, an intravenous chemotherapy medication classified under ATC code L01AA03. Manufactured primarily by Indian pharmaceutical company Celon Laboratories, Alkacel presents an alternative formulation to the UK-dominant Alkeran brand. Healthcare professionals typically administer Alkacel from lyophilised powder stored in light-protective amber vials. Despite not holding direct Medicines and Healthcare products Regulatory Agency approval, specialist UK pharmacies may source Alkacel through specific import protocols when clinically appropriate.
Pharmacology And Mechanism Of Action
How Alkacel Attacks Cancer Cells
Alkacel contains melphalan which functions as a nitrogen mustard alkylating agent. This specialised chemotherapy treatment modifies cancer DNA through cross-linking processes that prevent tumour cells from multiplying. By forming permanent bonds between DNA strands, Alkacel effectively stops cancerous cells from dividing and growing uncontrollably.
Metabolism And Elimination
After intravenous administration, Alkacel undergoes rapid hydrolysis (breakdown in body fluids) within approximately 10-15 minutes. Primary excretion occurs through renal pathways, meaning kidney function significantly influences melphalan clearance. Peak plasma concentrations typically occur within 30 minutes post-infusion, necessitating precise dosing calculations based on body surface area measurements.
Critical Medication Interactions
- NSAIDs: Combining nonsteroidal anti-inflammatory drugs like ibuprofen increases bleeding risks due to compounded platelet effects
- Live Vaccines: Avoid administration during Alkacel cycles due to potential immunosuppression compromising vaccine effectiveness
- Alcohol: Heightened hepatotoxicity concerns when combined; abstinence recommended throughout treatment cycles
- Ciclosporin: May increase renal toxicity potential requiring enhanced kidney function monitoring
Manufacturer Insights And UK Regulatory Position
Celon Laboratories manufactures Alkacel primarily for Indian and select global markets through an extensive pharmaceutical distribution network. The UK market remains dominated by GSK-manufactured Alkeran, which holds full Medicines and Healthcare products Regulatory Agency approval.
Notable regulatory considerations include:
- Alkacel lacks European Medicines Agency formal approval for mainstream UK distribution
- Specialist oncology centres occasionally import Alkacel under MHRA unlicensed medicine protocols
- National Health Service institutions typically procure Alkeran according to established chemotherapy procurement frameworks
- Quality assurance requirements still mandate Good Manufacturing Practice compliance for imported Alkacel
Critical Safety Considerations For Patients
Absolute contraindications for Alkacel treatment include confirmed hypersensitivity to melphalan and pregnancy due to established teratogenic risks associated with alkylating chemotherapy agents.
Special Population Precautions
| Population | Dosing Adjustment Required | Monitoring Protocol |
|---|---|---|
| Renal impairment (eGFR <60) | Reduce dose ≤50% | Serum creatinine before each cycle |
| Pediatric patients | Weight-based neuroblastoma protocols | Enhanced growth parameter tracking |
| Elderly patients (>70) | Initial 25% reduction | Comprehensive frailty assessment |
Secondary Cancer Risks
Long-term Alkacel use potentially increases susceptibility to acute myeloid leukaemia and myelodysplastic syndromes through cumulative DNA damage mechanisms. Oncology teams balance these risks against therapeutic benefits when recommending extended chemotherapy regimens.
Approved & Off-Label Indications
EU regulators approve Alkacel (melphalan) for specific cancer treatments, following European Medicines Agency guidelines. Key uses include multiple myeloma protocols and epithelial ovarian cancer management. National Cancer Research Network NHS recommendations endorse melphalan as conditioning therapy for bone marrow transplants – a widespread off-label application with established safety data. Other off-label treatments incorporate soft tissue sarcoma regimens and selected neuroblastoma cases in paediatric oncology.
Special population protocols remain tightly controlled. For pregnancy category D medicines like Alkacel, clinicians may consider treatment only when urgent maternal cancer therapy outweighs documented fetal toxicity risks. Published miscarriage and congenital malformation risks require explicit patient consent. Treatment cessation occurs immediately post-partum, with contraindications in breastfeeding due to infant bone marrow suppression hazards. Unapproved applications like melanoma or gastric cancers lack sufficient evidence for routine practice.
Dosage & Clinical Protocols
Alkacel administration demands precision oncology protocols. Myeloma treatment typically requires 16mg/m² intravenous doses, calculated using patient body surface area. Ovarian cancer protocols often use 0.2mg/kg daily across five-day cycles. Hospital staff reconstitute lyophilised powder with provided solvent, achieving clear solutions before diluting in saline. Administration requires 15–20 minute IV infusions via central lines, avoiding rapid injection risks.
| Indication | Dosage | Frequency |
|---|---|---|
| Multiple Myeloma | 16mg/m² | Every 2–4 weeks |
| Ovarian Cancer | 0.2mg/kg daily | 5-day cycles monthly |
| BMT Conditioning | 140–200mg/m² | Single pre-transplant dose |
Strict cytotoxic handling rules apply: refrigerate unopened vials below 25°C, protect from light, and dispose of spills with chemical deactivation kits. Reconstituted solutions degrade within hours - immediate use is essential. Pharmacy teams validate chemotherapy doses before release.
Side Effects & Critical Safety Concerns
Alkacel treatment carries significant toxicity profiles requiring vigilant monitoring. Gastrointestinal reactions include oral mucositis-induced pain interfering with swallowing and chemotherapy-induced nausea requiring anti-emetic premedication. Haematological disturbances span:
- Neutropenia causing sepsis vulnerability
- Thrombocytopenia requiring platelet transfusion thresholds
- Anaemia management with blood product support
UK guidelines mandate absolute neutrophil count tracking weekly. Critical black box warnings highlight irreversible bone marrow failure and secondary leukaemia risks after prolonged treatment. Life-threatening complications involve mucositis-linked sepsis and drug-induced pneumonitis. Rapid intervention protocols activate for fever during neutropenia or haemorrhage with platelet counts under 20×109/L. Pulmonary function testing occurs biannually for chronic users.
Patient & Caregiver Experience
Cancer forums reveal polarised Alkacel perspectives. Myeloma patients reporting 60% response rates describe profound disease control enabling stem cell transplants. One Blood Cancer UK member stated: "After four Alkacel cycles, my cancer markers finally dropped to transplant levels - it gave me a fighting chance." Conversely, significant toxicity burdens surface repeatedly in discussions. Caregivers describe debilitating fatigue, traumatic mouth ulcer management, and emotional turmoil during neutropenia lockdowns requiring hospital isolation.
UK-specific barriers include limited rural chemotherapy centre access requiring overnight stays and significant out-of-pocket parking costs. NHS prescription charges for anti-sickness drugs compound financial strain. Practical challenges emerge with treatment scheduling rigidity - shifts cancelling transfusions disrupt work commitments. Such factors contribute to data showing 32% non-adherence among outpatients managing complex regimens without nursing support.
Brand Alternatives and UK Pricing Insights
In the UK oncology sector, Melphalan treatments vary significantly in cost and availability. Hospital pharmacies predominantly stock Alkeran (£150 per 50mg vial), while specialist importers supply generic versions like Alkacel at £120-180 per vial. These medicines exist as lyophilised powders requiring reconstitution, exclusively supplied in amber-glass vials maintaining cold-chain integrity throughout transport.
| Brand | Price (per 50mg vial) | UK Availability |
|---|---|---|
| Alkeran (GSK) | £150 | Hospital pharmacies |
| Melphalan Sandoz | £135-£160 | Specialist distributors |
| Evomela (Spectrum) | £200-£250 | Specialist cancer centres |
| Alkacel (Celon) | £120-£180 | Unlicensed import only |
Recent NHS expenditure patterns show myeloma treatment costs rising 7% annually, partly influenced by formulation differences. Evomela's solubilised format demands premium pricing despite therapeutic equivalence. Patients seeking unlicensed generics like Alkacel face variable lead times from importers, though verification of temperature-controlled logistic compliance remains essential.
Research Advancements and Patent Status
Recent clinical developments focus on enhancing Melphalan's efficacy through novel delivery systems and combination protocols. The RECOVERY-M trial demonstrated significantly improved response rates when combining Melphalan with Bortezomib versus standalone administration.
Patents protecting Melphalan formulations expired between 2020–2023, enabling Indian manufacturers like Celon Labs to enter generic production. Current pipeline investigations include intra-arterial delivery for liver metastases and nanoparticle encapsulation for reduced nephrotoxicity.
Patient Guidance and Safety Questions
Pain management during therapy warrants careful consideration. Avoid NSAIDs entirely due to severe bleeding risk with Alkacel treatment. Paracetamol represents the safest analgesic choice.
Regarding vaccinations, postpone live vaccines for at least three months post-treatment completion. Temporary hair thinning commonly occurs but typically reverses within 6-9 months after chemotherapy concludes.
Transportation concerns frequently arise. Refrain from driving immediately following infusions due to possible dizziness. Consult your oncology team before any journey requiring concentration.
UK Supply and Distribution Dynamics
The NHS procurement framework prioritises licensed products through hospital pharmacies, rendering Alkacel access challenging unless prescribed through Named Patient basis. Boots and LloydsPharmacy locations typically provide licensed alternatives like Alkeran following standard oncology pathways. Specialised importers manage Alkacel distribution which requires temperature-monitored transit documentation.
Chemotherapy access trends indicate myeloma treatment demand grew 2.8% in 2023 across England. Specialist pharmacies maintain stringent cold-chain validation through refrigerated vehicles and thermal packaging, critical for preservative-free formulations.
Essential Administration Protocol
Correct handling ensures therapeutic efficacy and safety. Adhere strictly to infusion scheduling consistency – variations exceed 48 hours require dose recalibration.
Crucial administration steps: - Verify intact vial seal before reconstitution - Use refrigerated saline exclusively as diluent - Administer infusion within four hours of preparation - Discard unused solution immediately
Critical errors include skipping fortnightly CBC monitoring and improper cytotoxic waste disposal. Double-glove during handling and utilise NHS-approved sharps containers.
