Generic Alkacel (Melphalan)

Introduction

Alkacel is an oral chemotherapy medication whose active ingredient is melphalan, an alkylating agent belonging to the nitrogen-mustard class. It is supplied as 2 mg tablets and is primarily indicated for the treatment of certain hematologic malignancies and solid tumours. Melphalan interferes with DNA replication, leading to tumour cell death. The drug is classified as an antineoplastic agent and is marketed in several countries under the brand name Alkacel. In addition to its approved uses, melphalan has been investigated for a number of off-label applications, although such uses have not received regulatory approval from the U.S. Food and Drug Administration (FDA) or the European Medicines Agency (EMA).

What is Alkacel?

• Definition - Alkacel is a tablet formulation that contains 2 mg of melphalan per pill.
• Classification - It is an alkylating chemotherapy agent used to treat cancer.
• Development history - Melphalan was first synthesized in the s as part of the nitrogen-mustard family of compounds and received FDA approval for multiple myeloma in 1968. Alkacel represents a modern generic tablet version of this historic molecule.
• Manufacturer - The specific manufacturer of Alkacel varies by market; the product is produced under licence by qualified pharmaceutical firms that meet Good Manufacturing Practice (GMP) standards.
• Brand context - Melphalan is also marketed under brand names such as Alkeran® (injectable) and Melphalan® (tablet) in several jurisdictions. Mention of these names improves search relevance for patients looking for generic alternatives.

How Alkacel Works

Melphalan is a bifunctional alkylating agent. After oral absorption, it circulates systemically and forms highly reactive aziridinium intermediates that covalently bind to the N7 position of guanine bases in DNA. This cross-linking prevents DNA strand separation, halting replication and transcription. Cancer cells, which divide rapidly, are preferentially affected because they rely on continuous DNA synthesis. The drug’s antitumour effect typically begins within 24 hours of ingestion, while plasma concentrations decline with a half-life of approximately 90 minutes, followed by renal excretion of unchanged drug and metabolites.

Conditions Treated with Alkacel

Approved indications (as per FDA/EMA labeling)

• Multiple myeloma - Used as part of high-dose conditioning regimens prior to autologous stem-cell transplantation. The alkylating action reduces tumour burden and facilitates engraftment.
• Ovarian cancer (adjuvant) - Administered after cytoreductive surgery and platinum-based chemotherapy to eradicate residual microscopic disease.
• Advanced malignant melanoma (historical) - In some regions, melphalan is approved for isolated limb perfusion, though the oral tablet formulation is not indicated for this use.

The efficacy of Alkacel in these settings is supported by randomized clinical trials demonstrating improved progression-free survival when melphalan is incorporated into multimodal regimens.

Off-Label and Investigational Uses of Alkacel

• Neuroblastoma (pediatric) - Small phase-II studies have explored oral melphalan as part of consolidation therapy after induction, showing modest activity. This use remains off-label and is reserved for clinical-trial settings.
• Chronic lymphocytic leukemia (CLL) - Retrospective analyses suggest that low-dose melphalan may induce partial remissions, but no prospective trial has confirmed safety or efficacy for routine practice.
• Primary central nervous system lymphoma - Limited case series report responses when melphalan is combined with radiotherapy; however, the regimen is experimental.

All off-label applications are not approved by regulatory agencies. Patients should discuss any such consideration with a qualified oncology specialist, and use should occur only within accredited clinical trials or under strict medical supervision.

Is Alkacel the Right Medication for You?

Alkacel is appropriate for adult patients who:

• Have a confirmed diagnosis of multiple myeloma scheduled for high-dose conditioning, or
• Have completed standard ovarian cancer surgery and systemic therapy and require adjuvant chemotherapy, and
• Possess adequate bone-marrow reserve (absolute neutrophil count ≥ 1.5 × 10⁹/L, platelet count ≥ 100 × 10⁹/L),

and who have no contraindications listed below.

Contraindications - Known hypersensitivity to melphalan or other nitrogen-mustard agents, severe renal impairment (creatinine clearance < 30 mL/min), active uncontrolled infection, or pregnancy/breast-feeding. Women of child-bearing potential must use reliable contraception during treatment and for at least 6 months after the last dose.

Risks, Side Effects, and Interactions

Common

• Nausea or vomiting
• Fatigue and malaise
• Mild reversible neutropenia
• Thrombocytopenia (platelet count < 150 × 10⁹/L)

Rare

• Secondary malignancies (e.g., therapy-related acute myeloid leukaemia)
• Ototoxicity (high-frequency hearing loss)
• Pulmonary fibrosis (particularly with high cumulative doses)

Serious

• Severe myelosuppression leading to infection or bleeding
• Acute renal failure (especially in patients with pre-existing kidney disease)
• Anaphylaxis (rare)

Drug-drug interactions

• Azathioprine, cyclophosphamide, and other alkylators - additive myelosuppression; dose adjustments required.
• Allopurinol - may increase melphalan plasma levels; monitor blood counts.
• Live vaccines - contraindicated while on Alkacel due to immunosuppression.

Drug-food interactions

• High-protein meals can modestly decrease oral absorption; take the tablet with a small amount of water, preferably on an empty stomach unless gastrointestinal upset occurs.
• Alcohol should be avoided, as it can exacerbate nausea and hepatic toxicity.

Use: Dosing, Missed Dose, Overdose

• Standard dosing - Adults typically receive 2 mg oral tablets once daily for 5 consecutive days per cycle, followed by a rest period of at least 21 days. Dose intensity may be modified based on body surface area, renal function, and hematologic parameters.
• Missed dose - If a dose is omitted and the next scheduled dose is more than 12 hours away, skip the missed tablet and resume the regular schedule. Do not double-dose to compensate.
• Overdose - Suspected overdose (e.g., ingestion of > 4 mg within 24 hours) requires immediate medical evaluation. Supportive care includes aggressive hydration, anti-emetics, and close monitoring of blood counts and renal function. In severe cases, administration of the alkylating-agent antidote mesna may be considered under specialist guidance.
• Practical precautions - Do not operate heavy machinery or drive while experiencing significant dizziness or neuropathy. Alcohol consumption should be avoided during treatment cycles. Store tablets at 20-25 °C in a dry place; keep out of reach of children.

FAQ

• What should I do with Alkacel tablets if I am traveling internationally?   Keep the medication in its original packaging, protected from heat and moisture. Carry a copy of the prescribing information and a letter from your physician (if requested) to satisfy customs authorities.

• Does the color or shape of Alkacel tablets vary by region?   Yes. Manufacturers may use different imprint codes, tablet colors, or shapes to differentiate batches that comply with local regulatory standards. Always verify the imprint code against the packaging label.

• Can I store Alkacel in a bathroom cabinet?   No. The bathroom environment often experiences humidity and temperature fluctuations that can degrade the tablet. Store the medication in a cool, dry place such as a bedroom drawer.

• Are any of the tablet’s inactive ingredients known allergens?   Alkacel tablets may contain lactose, microcrystalline cellulose, and magnesium stearate. Patients with lactose intolerance or specific excipient allergies should review the full ingredient list before use.

• Is there a risk of a positive drug test while taking Alkacel?   Standard employment or sports drug screens do not test for melphalan. However, specialized toxicology panels could detect it; disclose your medication status to the testing authority if required.

• How does Alkacel compare to the injectable form Alkeran?   Both contain the same active molecule, melphalan, but the oral tablet offers convenience and avoids infusion-related reactions. Bioavailability of the oral form is lower (≈ 30 %) compared with intravenous administration, so dosing adjustments are necessary.

• What is the typical duration of a treatment cycle with Alkacel?   A conventional cycle consists of 5 days of daily dosing followed by a 21-day rest period, aligning with bone-marrow recovery. The total number of cycles depends on disease response and tolerability.

• Can Alkacel be taken with over-the-counter (OTC) pain relievers?   Acetaminophen is generally safe, but non-steroidal anti-inflammatory drugs (NSAIDs) may increase the risk of gastrointestinal bleeding, especially when myelosuppression is present. Consult a pharmacist before combining.

• Is it necessary to have my blood counts checked before each dose?   Yes. Baseline and pre-dose complete blood counts are essential to ensure neutrophil and platelet levels remain within safe limits, reducing the risk of severe myelosuppression.

• Does Alkacel require any special disposal methods?   Unused tablets and contaminated packaging should be disposed of according to local hazardous-waste guidelines or returned to a pharmacy with a drug-take-back program to protect the environment and prevent accidental exposure.
