📖 What it is MedlinePlus · NLM

Melphalan injection is used to treat multiple myeloma (a type of cancer of the bone marrow) in people who are unable to take melphalan by mouth. Melphalan injection is also used to destroy bone marrow and cancer cells in preparation for a bone marrow transplant in people with multiple myeloma. Melphalan is in a class of medications called alkylating agents. It works by stopping or slowing the growth of cancer cells in your body.

🧪 Inactive Ingredients / Excipients

Inactive ingredients, also called excipients, are components of the drug product other than the active ingredient. They may include fillers, dyes, coatings, preservatives, flavors, or other formulation ingredients.

A current SPL was checked, but it does not contain a structured or narrative inactive-ingredient list for this product. This does not mean the product has no inactive ingredients.
Where does this data come from?
Source: official FDA Structured Product Labeling (SPL) via DailyMed and the openFDA label index. Structured IACT rows and label-wide narrative are kept separate; availability and product-level specificity depend on the submitted label.

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?
No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.
Why might an inactive ingredient be missing?
Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.
Can inactive ingredients matter?
Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

💲 Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The FDA registers it as 23155-355-41, which is what is printed on the packaging and shown on DailyMed. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero: 23155-0355-41, written without dashes as 23155035541. The Identity section at the top of this page lists every form of this code.
What do the three segments of this NDC mean?
In 23155-0355-41, the first segment (23155) is the labeler code FDA assigned to Heritage Pharmaceuticals Inc. d/b/a Avet Pharmaceuticals Inc.; the middle segment (0355) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (41) identifies this exact package size and type. Together they name one specific package of one specific product.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by Heritage Pharmaceuticals Inc. d/b/a Avet Pharmaceuticals Inc.. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
Heritage Pharmaceuticals Inc. d/b/a Avet Pharmaceuticals Inc. is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
Does this product have a billing J-code?
Yes — this NDC cross-references HCPCS code J9245 for medical-claim billing (typically used when a product is administered in a clinical setting rather than dispensed at a retail pharmacy). See the Billing section on this page.
This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.

🚨 Boxed Warning 87 words

BOXED WARNING Melphalan should be administered under the supervision of a qualified physician experienced in the use of cancer chemotherapeutic agents. Severe bone marrow suppression with resulting infection or bleeding may occur. Controlled trials comparing intravenous (IV) to oral melphalan have shown more myelosuppression with the IV formulation.

Hypersensitivity reactions, including anaphylaxis, have occurred in approximately 2% of patients who received the IV formulation. Melphalan is leukemogenic in humans. Melphalan produces chromosomal aberrations in vitro and in vivo and, therefore, should be considered potentially mutagenic in humans.

🎯 Indications and Usage 25 words

INDICATIONS AND USAGE Melphalan Hydrochloride for Injection is indicated for the palliative treatment of patients with multiple myeloma for whom oral therapy is not appropriate.

⏱️ Dosage and Administration ~2 min read

DOSAGE AND ADMINISTRATION The usual IV dose is 16 mg/m 2 . Dosage reduction of up to 50% should be considered in patients with renal insufficiency (BUN greater than or equal to 30 mg/dL) (see PRECAUTIONS: General ). The drug is administered as a single infusion over 15 to 20 minutes.

Melphalan is administered at 2-week intervals for 4 doses, then, after adequate recovery from toxicity, at 4-week intervals. Available evidence suggests about one third to one half of the patients with multiple myeloma show a favorable response to the drug. Experience with oral melphalan suggests that repeated courses should be given since improvement may continue slowly over many months, and the maximum benefit may be missed if treatment is abandoned prematurely.

Dose adjustment on the basis of blood cell counts at the nadir and day of treatment should be considered. Administration Precautions As with other toxic compounds, caution should be exercised in handling and preparing the solution of Melphalan Hydrochloride. Skin reactions associated with accidental exposure may occur.

The use of gloves is recommended. If the solution of Melphalan Hydrochloride contacts the skin or mucosa, immediately wash the skin or mucosa thoroughly with soap and water. Procedures for proper handling and disposal of anticancer drugs should be considered.

Several guidelines on this subject have been published. 1-4 There is no general agreement that all of the procedures recommended in the guidelines are necessary or appropriate. Parenteral drug products should be visually inspected for particulate matter and discoloration prior to administration whenever solution and container permit.

If either occurs, do not use this product. Care should be taken to avoid possible extravasation of melphalan and in cases of poor peripheral venous access, consideration should be given to use of a central venous line (see WARNINGS ). Preparation for Administration/Stability Melphalan Hydrochloride for Injection must be reconstituted by rapidly injecting 10 mL of the supplied diluent directly into the vial of lyophilized powder using a sterile needle (20-gauge or larger needle diameter) and syringe.

Immediately shake vial vigorously until a clear solution is obtained. This provides a 5-mg/mL solution of melphalan. Rapid addition of the diluent followed by immediate vigorous shaking is important for proper dissolution.

Immediately dilute the dose to be administered in 0.9% Sodium Chloride Injection, USP, to a concentration not greater than 0.45 mg/mL. Administer the diluted product over a minimum of 15 minutes. Complete administration within 60 minutes of reconstitution.

The time between reconstitution/dilution and administration of Melphalan Hydrochloride should be kept to a minimum because reconstituted and diluted solutions of Melphalan Hydrochloride are unstable. Over as short a time as 30 minutes, a citrate derivative of melphalan has been detected in reconstituted material from the reaction of Melphalan Hydrochloride for with Sterile Diluent for Melphalan Hydrochloride. Upon further dilution with saline, nearly 1% label strength of melphalan hydrolyzes every 10 minutes.A precipitate forms if the reconstituted solution is stored at 5°C.

DO NOT REFRIGERATE THE RECONSTITUTED PRODUCT.

Contraindications 30 words

CONTRAINDICATIONS Melphalan should not be used in patients whose disease has demonstrated prior resistance to this agent. Patients who have demonstrated hypersensitivity to melphalan should not be given the drug.

⚠️ Warnings ~3 min read

WARNINGS Melphalan Hydrochloride for Injection may cause local tissue damage should extravasation occur, and consequently it should not be administered by direct injection into a peripheral vein. It is recommended that Melphalan Hydrochloride for Injection be administered by injecting slowly into a fast-running IV infusion via an injection port, or via a central venous line (see DOSAGE AND ADMINISTRATION: Administration Precautions ). Melphalan should be administered in carefully adjusted dosage by or under the supervision of experienced physicians who are familiar with the drug's actions and the possible complications of its use.

As with other nitrogen mustard drugs, excessive dosage will produce marked bone marrow suppression. Bone marrow suppression is the most significant toxicity associated with Melphalan Hydrochloride for Injection in most patients. Therefore, the following tests should be performed at the start of therapy and prior to each subsequent dose of Melphalan Hydrochloride for Injection: platelet count, hemoglobin, white blood cell count, and differential.

Thrombocytopenia and/or leukopenia are indications to withhold further therapy until the blood counts have sufficiently recovered. Frequent blood counts are essential to determine optimal dosage and to avoid toxicity. Dose adjustment on the basis of blood counts at the nadir and day of treatment should be considered.

Hypersensitivity reactions including anaphylaxis have occurred in approximately 2% of patients who received the IV formulation (see ADVERSE REACTIONS ). These reactions usually occur after multiple courses of treatment. Treatment is symptomatic.

The infusion should be terminated immediately, followed by the administration of volume expanders, pressor agents, corticosteroids, or antihistamines at the discretion of the physician. If a hypersensitivity reaction occurs, IV or oral melphalan should not be readministered since hypersensitivity reactions have also been reported with oral melphalan. Carcinogenesis Secondary malignancies, including acute nonlymphocytic leukemia, myeloproliferative syndrome, and carcinoma, have been reported in patients with cancer treated with alkylating agents (including melphalan).

Some patients also received other chemotherapeutic agents or radiation therapy. Precise quantitation of the risk of acute leukemia, myeloproliferative syndrome, or carcinoma is not possible. Published reports of leukemia in patients who have received melphalan (and other alkylating agents) suggest that the risk of leukemogenesis increases with chronicity of treatment and with cumulative dose.

In one study, the 10-year cumulative risk of developing acute leukemia or myeloproliferative syndrome after oral melphalan therapy was 19.5% for cumulative doses ranging from 730 to 9,652 mg. In this same study, as well as in an additional study, the 10-year cumulative risk of developing acute leukemia or myeloproliferative syndrome after oral melphalan therapy was less than 2% for cumulative doses under 600 mg. This does not mean that there is a cumulative dose below which there is no risk of the induction of secondary malignancy.

The potential benefits from melphalan therapy must be weighed on an individual basis against the possible risk of the induction of a second malignancy. Adequate and well-controlled carcinogenicity studies have not been conducted in animals. However, intraperitoneal (IP) administration of melphalan in rats (5.4 to 10.8 mg/m 2 ) and in mice (2.25 to 4.5 mg/m 2 ) 3 times per week for 6 months followed by 12 months post-dose observation produced peritoneal sarcoma and lung tumors, respectively.

Mutagenesis Melphalan has been shown to cause chromatid or chromosome damage in humans. Intramuscular administration of melphalan at 6 and 60 mg/m 2 produced structural aberrations of the chromatid and chromosomes in bone marrow cells of Wistar rats. Impairment of Fertility Melphalan causes suppression of ovarian function in premenopausal w…

🤒 Adverse Reactions ~1 min read

ADVERSE REACTIONS (SEE OVERDOSAGE ) The following information on adverse reactions is based on data from both oral and IV administration of melphalan as a single agent, using several different dose schedules for treatment of a wide variety of malignancies. Hematologic The most common side effect is bone marrow suppression leading to leukopenia, thrombocytopenia, and anemia. White blood cell count and platelet count nadirs usually occur 2 to 3 weeks after treatment, with recovery in 4 to 5 weeks after treatment.

Irreversible bone marrow failure has been reported. Gastrointestinal Gastrointestinal disturbances such as nausea and vomiting, diarrhea, and oral ulceration occur infrequently. Hepatic disorders ranging from abnormal liver function tests to clinical manifestations such as hepatitis and jaundice have been reported.

Hepatic veno-occlusive disease has been reported. Hypersensitivity Acute hypersensitivity reactions including anaphylaxis were reported in 2.4% of 425 patients receiving Melphalan Hydrochloride for Injection for myeloma (see WARNINGS ). These reactions were characterized by urticaria, pruritus, edema, skin rashes, and in some patients, tachycardia, bronchospasm, dyspnea, and hypotension.

These patients appeared to respond to antihistamine and corticosteroid therapy. If a hypersensitivity reaction occurs, IV or oral melphalan should not be readministered since hypersensitivity reactions have also been reported with oral melphalan. Cardiac arrest has also been reported rarely in association with such reports.

Miscellaneous Other reported adverse reactions include skin hypersensitivity, skin ulceration at injection site, skin necrosis rarely requiring skin grafting, maculopapular rashes, vasculitis, alopecia, hemolyticanemia, allergic reaction, pulmonary fibrosis (including fatal outcomes), and interstitial pneumonitis. Temporary significant elevation of the blood urea has been seen in the early stages of therapy in patients with renal damage. Subjective and transient sensation of warmth and/or tingling.

🔄 Drug Interactions 212 words

Drug Interactions The development of severe renal failure has been reported in patients treated with a single dose of IV melphalan followed by standard oral doses of cyclosporine. Cisplatin may affect melphalan kinetics by inducing renal dysfunction and subsequently altering melphalan clearance. IV melphalan may also reduce the threshold for BCNU lung toxicity.

When nalidixic acid and IV melphalan are given simultaneously, the incidence of severe hemorrhagic necrotic enterocolitis has been reported to increase in pediatric patients. Carcinogenesis, Mutagenesis, Impairment of Fertility See WARNINGS section. Pregnancy Teratogenic Effects See WARNINGS section.

Nursing Mothers It is not known whether this drug is excreted in human milk. IV melphalan should not be given to nursing mothers. Pediatric Use The safety and effectiveness in pediatric patients have not been established.

Geriatric Use Clinical studies of Melphalan Hydrochloride for Injection did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

🆘 Overdosage 177 words

OVERDOSAGE Overdoses resulting in death have been reported. Overdoses, including doses up to 290 mg/m 2 , have produced the following symptoms: severe nausea and vomiting, decreased consciousness, convulsions, muscular paralysis, and cholinomimetic effects. Severe mucositis, stomatitis, colitis, diarrhea, and hemorrhage of the gastrointestinal tract occur at high doses (greater than 100 mg/m 2 ).

Elevations in liver enzymes and veno-occlusive disease occur infrequently. Significant hyponatremia caused by an associated inappropriate secretion of ADH syndrome has been observed. Nephrotoxicity and adult respiratory distress syndrome have been reported rarely.

The principal toxic effect is bone marrow suppression. Hematologic parameters should be closely followed for 3 to 6 weeks. An uncontrolled study suggests that administration of autologous bone marrow or hematopoietic growth factors (i.e., sargramostim, filgrastim) may shorten the period of pancytopenia.

General supportive measures together with appropriate blood transfusions and antibiotics should be instituted as deemed necessary by the physician. This drug is not removed from plasma to any significant degree by hemodialysis or hemoperfusion. A pediatric patient survived a 254-mg/m 2 overdose treated with standard supportive care.

🧬 Clinical Pharmacology ~3 min read

CLINICAL PHARMACOLOGY Melphalan is an alkylating agent of the bischloroethylamine type. As a result, its cytotoxicity appears to be related to the extent of its interstrand cross-linking with DNA, probably by binding at the N 7 position of guanine. Like other bifunctional alkylating agents, it is active against both resting and rapidly dividing tumor cells.

Pharmacokinetics Following injection, drug plasma concentrations declined rapidly in a biexponential manner with distribution phase and terminal elimination phase half-lives of approximately 10 and 75 minutes, respectively. Estimates of average total body clearance varied among studies, but typical values of approximately 7 to 9 mL/min/kg (250 to 325 mL/min/m 2 ) were observed. One study has reported that on repeat dosing of 0.5 mg/kg every 6 weeks, the clearance of melphalan decreased from 8.1 mL/min/kg after the first course, to 5.5 mL/min/kg after the third course, but did not decrease appreciably after the third course.

Mean (±SD) peak melphalan plasma concentrations in myeloma patients given IV melphalan at doses of 10 or 20 mg/m 2 were 1.2 ± 0.4 and 2.8 ± 1.9 mcg/mL, respectively. The steady-state volume of distribution of melphalan is

0.5L/kg. Penetration into cerebrospinal fluid (CSF) is low. The average melphalan binding to plasma proteins is highly variable (range: 53% to 92%).

Serum albumin is the major binding protein, accounting for approximately 40% to 60% of the plasma protein binding, while α1-acid glycoprotein accounts for about 20% of the plasma protein binding. Approximately 30% of melphalan is (covalently) irreversibly bound to plasma proteins. Interactions with immunoglobulins have been found to be negligible.

Melphalan is eliminated from plasma primarily by chemical hydrolysis to monohydroxymelphalan and dihydroxymelphalan. Aside from these hydrolysis products, no other melphalan metabolites have been observed in humans. Although the contribution of renal elimination to melphalan clearance appears to be low, one study noted an increase in the occurrence of severe leukopenia in patients with elevated BUN after 10 weeks of therapy.

Clinical Trial A randomized trial compared prednisone plus IV melphalan to prednisone plus oral melphalan in the treatment of myeloma. As discussed below, overall response rates at week 22 were comparable; however, because of changes in trial design, conclusions as to the relative activity of the 2 formulations after week 22 are impossible to make.Both arms received oral prednisone starting at 0.8 mg/kg/day with doses tapered over 6 weeks. Melphalan doses in each arm were: Arm 1: Oral melphalan 0.15 mg/kg/day x 7 followed by 0.05 mg/kg/day when WBC began to rise.

Arm 2: IV melphalan 16 mg/m 2 q 2 weeks x 4 (over 6 weeks) followed by the same dose every 4 weeks. Doses of melphalan were adjusted according to the following criteria: Table 1. Criteria for Dosage Adjustment in a Randomized Clinical Trial WBC/mm 3 Platelets Percent of Full Dose ≥4,000 ≥100,000 100 ≥3,000 ≥75,000 75 ≥2,000 ≥50,000 50 <2,000 <50,000 0 One hundred seven patients were randomized to the oral melphalan arm and 203 patients to the IV melphalan arm.

More patients had a poor-risk classification (58% versus 44%) and high tumor load (51% versus 34%) on the oral compared to the IV arm ( P less than 0.04). Response rates at week 22 are shown in the following table: Table 2. Response Rates at Week 22 Initial Arm Evaluable Patients Responders n (%) P Oral melphalan 100 44 (44%) P >

0.2IV melphalan 195 74 (38%) Because of changes in protocol design after week 22, other efficacy parameters such as response duration and survival cannot be compared. Severe myelotoxicity (WBC less than or equal to 1,000 and/or platelets less than or equal to 25,000) was more common in the IV melphalan arm (28%) than in the oral melphalan arm (11%). An association was noted between poor renal function and myelosuppression; consequently, an amendment to the protocol required a 50% redu…

📋 Description 206 words

DESCRIPTION Melphalan, also known as L-phenylalanine mustard, phenylalanine mustard, L-PAM, or L-sarcolysin, is a phenylalanine derivative of nitrogen mustard. Melphalan is a bifunctional alkylating agent that is active against selected human neoplastic diseases. It is known chemically as 4-[bis(2-chloroethyl)amino]- L- phenylalanine.

The molecular formula is C 13 H 18 Cl 2 N 2 O 2 and the molecular weight is 305.20. The structural formula is: Melphalan is the active L-isomer of the compound and was first synthesized in 1953 by Bergel and Stock; the D-isomer, known as medphalan, is less active against certain animal tumors, and the dose needed to produce effects on chromosomes is larger than that required with the L-isomer. The racemic (DL-) form is known as merphalan or sarcolysin.Melphalan is practically insoluble in water and has a pKa1 of ~2.5.

Melphalan Hydrochloride for Injection is supplied as a sterile, nonpyrogenic, freeze-dried powder. Each single-dose vial contains melphalan hydrochloride equivalent to 50 mg melphalan and 20 mg povidone. Melphalan Hydrochloride for Injection is reconstituted using the sterile diluent provided.

Each vial of sterile diluent contains sodium citrate 0.2 g, propylene glycol 6.0 mL, ethanol (96%) 0.52 mL, and Water for Injection to a total of 10 mL.Melphalan Hydrochloride for Injection is administered intravenously. structure
