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.

🎯 Indications and Usage 195 words ▾

1 INDICATIONS AND USAGE PANHEMATIN is a hemin for injection indicated for the amelioration of recurrent attacks of acute intermittent porphyria temporally related to the menstrual cycle in susceptible women, after initial carbohydrate therapy is known or suspected to be inadequate. Limitations of Use • Before administering PANHEMATIN, consider an appropriate period of carbohydrate loading (i.e., 400 g glucose/day for 1 to 2 days) [ See Dosage and Administration ( 2.1 ) ]. • Attacks of porphyria may progress to a point where irreversible neuronal damage has occurred.

PANHEMATIN therapy is intended to prevent an attack from reaching the critical stage of neuronal degeneration. PANHEMATIN is not effective in repairing neuronal damage. PANHEMATIN is a hemin for injection indicated for amelioration of recurrent attacks of acute intermittent porphyria temporally related to the menstrual cycle in susceptible women, after initial carbohydrate therapy is known or suspected to be inadequate.

( 1 ) Limitations of Use • Before administering PANHEMATIN, consider an appropriate period of carbohydrate loading (i.e., 400 g glucose/day for 1 to 2 days). ( 1 ) • PANHEMATIN is not effective in repairing neuronal damage due to progression of porphyria attacks. ( 1 )

⏱️ Dosage and Administration ~3 min read ▾

2 DOSAGE AND ADMINISTRATION For intravenous infusion only. For intravenous infusion only. Dose ( 2.1 ) 1 to 4 mg/kg/day for 3 to 14 days based on the clinical signs.

The standard dose in clinical practice is 3 to 4 mg/kg/day. Repeat dose in more severe cases no earlier than every 12 hours. Do not exceed 6 mg/kg in any 24 hour period.

Administration ( 2.2 ) Use sterile 0.45 micron or smaller filter to remove any undissolved particulate matter. The dose may be administered directly from the vial over a period of at least 30 minutes. After the infusion, flush the vein with 100 mL of 0.9% NaCl.

2.1Dosing • PANHEMATIN should only be used by or in consultation with physicians experienced in the management of porphyrias. • Before PANHEMATIN therapy is begun, the presence of acute porphyria must be diagnosed using the following criteria: 1. Presence of clinical symptoms suggestive of acute porphyric attack. 2.

Quantitative measurement of porphobilinogen (PBG) in urine. The single-void urine sample should be refrigerated or frozen without additives and shielded from light for subsequent quantitative δ-aminolevulinic acid (ALA), PBG, and total porphyrin determinations. (Note: the classical Watson-Schwartz or Hoesch tests are considered to be less reliable). • Clinical benefit from PANHEMATIN depends on prompt administration.

For mild porphyric attacks (mild pain, no vomiting, no paralysis, no hyponatremia, no seizures), a trial of glucose therapy is recommended while awaiting hemin treatment or if hemin is unavailable. For moderate to severe attacks, immediate hemin treatment is recommended. Symptoms of severe attacks are severe or prolonged pain, persistent vomiting, hyponatremia, convulsion, psychosis, and neuropathy.

In addition to treatment with PANHEMATIN, consider other necessary measures such as the elimination of triggering factors. • The dose of PANHEMATIN is 1 to 4 mg/kg/day of hematin for 3 to 14 days based on the clinical signs. The standard dose in clinical practice is 3 to 4 mg/kg/day. In more severe cases this dose may be repeated no earlier than every 12 hours.

Do not exceed 6 mg/kg of hematin in any 24 hour period. After reconstitution each mL of PANHEMATIN contains the equivalent of approximately 7 mg of hematin (see dosage calculation table below). Dosage Calculation Table 1 mg hematin equivalent = 0.14 mL PANHEMATIN 2 mg hematin equivalent = 0.28 mL PANHEMATIN 3 mg hematin equivalent = 0.42 mL PANHEMATIN 4 mg hematin equivalent = 0.56 mL PANHEMATIN • Monitor urinary concentrations of the following compounds during PANHEMATIN therapy.

Effectiveness is demonstrated by a decrease in one or more of the following compounds. ALA - δ-aminolevulinic acid PBG - porphobilinogen Uroporphyrin Coproporphyrin

2.2Preparation and Administration • Because PANHEMATIN contains no preservative and undergoes rapid chemical decomposition in solution, it must be reconstituted immediately before use. • Reconstitute PANHEMATIN by aseptically adding 48 mL of Sterile Water for Injection, USP, to the dispensing vial. Shake the vial well for a period of 2 to 3 minutes to aid dissolution. • PANHEMATIN may be administered directly from the vial. After the first withdrawal from the vial, discard any solution remaining. • Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

Since reconstituted PANHEMATIN is not transparent, any undissolved particulate matter is difficult to see when inspected visually. Therefore, terminal filtration through a sterile 0.45 micron or smaller filter is recommended. • Do not add other drug or chemical agent to a PANHEMATIN fluid admixture. • Infuse the dose over a period of at least 30 minutes via a separate line. • After the infusion, flush the vein with 100 mL of 0.9% NaCl.

⚠️ Warnings and Cautions ~2 min read ▾

5 WARNINGS AND PRECAUTIONS • Phlebitis is possible. Utilize a large arm vein or a central venous catheter for administration to minimize the risk of phlebitis. ( 5.1 ) • Elevated iron and serum ferritin may occur.

Monitor iron and serum ferritin in patients receiving multiple administrations of PANHEMATIN. ( 5.2 ) • PANHEMATIN has transient and mild anticoagulant effect. Avoid concurrent anticoagulant therapy.

( 5.3 ) • Reversible renal shutdown has been observed with an excessive hematin dose (12.2 mg/kg in a single infusion). Strictly follow recommended dosage guidelines. ( 5.4 ) • PANHEMATIN may carry a risk of transmitting infectious agents, e.g., viruses, and theoretically, the Creutzfeldt-Jakob disease (CJD) agent.

( 5.5 )

5.1Risk of Phlebitis A large arm vein or a central venous catheter should be utilized for the administration of PANHEMATIN to minimize the risk of phlebitis. Since reconstituted PANHEMATIN is not transparent, any undissolved particulate matter is difficult to see when inspected visually. Therefore, terminal filtration through a sterile 0.45 micron or smaller filter is recommended. [See Dosage and Administration ( 2.2 )]

5.2Iron and Serum Ferritin Because increased levels of iron and serum ferritin have been reported in post-marketing experience, physicians must monitor iron and serum ferritin in patients receiving multiple administrations of PANHEMATIN [See Adverse Reactions ( 6.2 )] . In case of elevated iron or serum ferritin levels, consider iron chelation therapy.

5.3Anticoagulant Effects Because PANHEMATIN has exhibited transient, mild anticoagulant effects during clinical studies, avoid concurrent anticoagulant therapy. The extent and duration of the hypocoagulable state induced by PANHEMATIN has not been established.

5.4Renal Effects Recommended dosage guidelines should be strictly followed. Reversible renal shutdown has been observed in a case where an excessive hematin dose (12.2 mg/kg) was administered in a single infusion. Oliguria and increased nitrogen retention occurred although the patient remained asymptomatic. No worsening of renal function has been seen with administration of recommended dosages of hematin.

5.5Transmissible Infectious Agents Because PANHEMATIN is made from human blood, it may carry a risk of transmitting infectious agents, e.g., viruses, the variant Creutzfeldt-Jacob disease (vCJD) agent, and theoretically the Creutzfeldt-Jacob disease (CJD) agent. The risk that this product may transmit an infectious agent has been reduced by screening blood donors for prior exposure to certain viruses, by testing for the presence of certain current virus infections, and by inactivating certain viruses. Despite these measures, this product can still potentially transmit disease.

There is also the possibility that unknown infectious agents may be present in the product. All infections thought by a physician possibly to have been transmitted by this product should be reported by the physician or other healthcare provider to Recordati Rare Diseases at 1-888-575-8344.

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety of PANHEMATIN use was evaluated in a compassionate use study. A total of 130 patients were treated with hemin for acute attacks, prophylaxis or both.

Of those, 111 patients were administered hemin for treatment of 305 acute porphyria attacks and to 40 patients for prophylaxis. The majority (92%) of patients were Caucasian. Most (72%) were female; all adult patients had a mean age ± SD of 40.3 ± 12.3 years.

Proportionally more females (15 out of 19) received prophylaxis or a combination of acute treatment and prophylaxis (19 out of 21). For the treatment of acute attacks, patients received 2 to 4 mg/kg/day PANHEMATIN intravenously for 1 to 9 doses. For prophylaxis patients, the most common doses were weekly or biweekly infusions.

6.2Postmarketing Experience The following adverse reactions associated with the use of PANHEMATIN were identified in open-label clinical trials or postmarketing reports. Because these reactions were reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency reliably or to establish a causal relationship to drug exposure. Blood and Lymphatic System Disorders: thrombocytopenia, coagulopathy (including prolonged prothrombin time and prolonged partial thromboplastin time), and hemolysis Immune System Disorders: hypersensitivity reactions including a report of infusion-related anaphylactoid reaction presenting as circulatory collapse Vascular Disorders: injection site venous thrombosis including some that occurred in large veins such as venae cavae General Disorders and Administration Site Conditions: infusion site reactions (such as erythema, pain, bleeding and extravasation) Metabolism and Nutrition Disorders: iron overload and serum ferritin increased [See Warnings and Precautions ( 5.2 )]

🔄 Drug Interactions 110 words ▾

7 DRUG INTERACTIONS PANHEMATIN therapy is intended to limit the rate of porphyria/heme biosynthesis possibly by inhibiting the enzyme δ-aminolevulinic acid synthetase 1 (ALAS1) [See Clinical Pharmacology ( 12.1 )] . Most of the heme synthesized in liver is used for the production of cytochrome P450 (CYP) enzymes. Therefore, avoid CYP inducing drugs (such as estrogens, barbituric acid derivatives and steroid metabolites) while on PANHEMATIN therapy, because these drugs increase the activity of ALAS leading to induction of ALAS1 through a feedback mechanism.

Avoid CYP inducing drugs such as estrogens, barbituric acid derivatives and steroid metabolites which induce δ-aminolevulinic acid synthetase 1 (ALAS1) through a feedback mechanism. ( 7 )

👥 Use in Specific Populations ~1 min read ▾

8 USE IN SPECIFIC POPULATIONS

8.1Pregnancy Risk Summary About 50% of the women with acute intermittent porphyria experience an acute attack of porphyria in pregnancy and/or the puerperium. It is most severe in early pregnancy and the puerperium, and can result in fatal outcome. Although anecdotal evidence suggests safe use of hematin during pregnancy, the available human data is not sufficient to establish the presence or absence of drug-associated risk.

Animal reproduction studies have not been conducted with hematin. It is also not known whether hematin can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. PANHEMATIN should be given to a pregnant woman only if clearly needed.

Avoid administering hematin in severe pre-eclampsia because of a theoretical risk of potentiation of the coagulation disorder [see Warnings and Precautions ( 5.3 )] . In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.

8.2Lactation Risk Summary It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, the developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for PANHEMATIN and any potential adverse effects on the breastfed child from PANHEMATIN or from the underlying maternal condition.

8.4Pediatric Use Safety and effectiveness in pediatric patients under 16 years of age have not been established.

8.5Geriatric Use Clinical data for subjects aged 65 and over was not sufficient to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in response 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.

🧬 Clinical Pharmacology 170 words ▾

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Heme acts to limit the hepatic and/or marrow synthesis of porphyrin. This action is likely due to the inhibition of δ-aminolevulinic acid synthetase, the enzyme which limits the rate of the porphyrin/heme biosynthetic pathway. The exact mechanism by which hematin produces symptomatic improvement in patients with acute episodes of the hepatic porphyrias has not been elucidated.

PANHEMATIN therapy for the acute porphyrias is not curative. After discontinuation of PANHEMATIN treatment, symptoms generally return although in some cases remission is prolonged. Some neurological symptoms have improved weeks to months after therapy although little or no response was noted at the time of treatment.

12.3Pharmacokinetics Following intravenous administration of hematin in non-jaundiced human patients, an increase in fecal urobilinogen can be observed which is roughly proportional to the amount of hematin administered. This suggests an enterohepatic pathway as at least one route of elimination. Bilirubin metabolites are also excreted in the urine following hematin injections. Other aspects of human pharmacokinetics have not been defined.

17 PATIENT COUNSELING INFORMATION • Advise the patient not to take drugs such as estrogens (e.g., oral contraceptives), barbiturates (drugs which help them to sleep and drugs sometimes used to treat epilepsy) or steroids (body hormone-like drugs), because this can trigger an attack or make the attack worse. • Advise a female patient to inform the prescriber if she is pregnant or planning to become pregnant.

🧬 Pharmacokinetics 61 words ▾

12.3Pharmacokinetics Following intravenous administration of hematin in non-jaundiced human patients, an increase in fecal urobilinogen can be observed which is roughly proportional to the amount of hematin administered. This suggests an enterohepatic pathway as at least one route of elimination. Bilirubin metabolites are also excreted in the urine following hematin injections. Other aspects of human pharmacokinetics have not been defined.

🔬 Clinical Studies ~3 min read ▾

14 CLINICAL STUDIES The effectiveness of PANHEMATIN for the amelioration of recurrent attacks of acute intermittent porphyria was evaluated in five open-label studies, one compassionate-use study, case reports, and an observational study investigating patient reported outcomes in patients with acute porphyrias. Open-Label Studies In the initial 5 open-label studies, 1-5 99 patients with acute porphyrias (72 with AIP) were treated with 3-4 mg/kg/day of hemin once or twice daily. Of the 99 patients in these studies, 30 received prior or concomitant glucose administration.

Patients experienced a clinical response in 85.5% (141/165) of treatment courses ( Figure 1 ). Clinical response was defined by improvement of symptoms and reduction in pain. All patients experienced a chemical response which was defined as normalization of urinary aminolevulinic acid (ALA) and porphobilinogen (PBG).

Watson et al. 1 studied the use of hemin treatment in 15 patients with acute porphyrias, of whom 11 were with AIP. Seven patients were female and four were male with an age range of 19-45 years with biochemical evidence of AIP.

Preparations of 4 mg/kg IV of hemin were infused at 12- or 24-hour intervals for 1 to 4 days after trials of glucose of various durations and dosages in all patients. All patients, with exception of one, experienced a clear clinical response most of which was rapid after hemin infusion. All patients also demonstrated a chemical response based on 58%-100% reduction in urinary ALA and PBG levels.

Pierach et al. 2 examined the use of 2 to 4 mg/kg of hemin IV in 57 patients with acute porphyrias, of whom 43 were with AIP. Out of 82 individual acute intermittent porphyria attacks with 476 hemin infusions (82 treatment courses) administered, a clinical response was seen in 74 (90%) acute attacks.

A chemical response was seen for those patients who had elevated urinary ALA and PBG levels prior to hemin treatment. McColl et al. 3 reported the use of 4 mg/kg of hemin IV given either every 12 or 24 hours for three to five days in the treatment of 13 attacks of acute porphyria in eight patients.

Seven of these 8 patients had AIP. Five patients with AIP were female and two were male with a mean age of 25 years (range 19-31 years). All patients had biochemical and clinical evidence of an attack of acute porphyria at the time of hemin administration.

All patients had a chemical response of approximately 50% reduction in urinary ALA and PBG from pre-treatment values. In addition, clinical response was seen after hemin treatment in a total of 7 attacks in 5 AIP patients. Lamon et al.

4 reported on 12 patients with acute porphyrias, of whom 11 were with AIP. These AIP patients received 190 infusions of approximately 2 to 4 mg/kg of hemin IV given every 12 or 24 hours for 3 to 13 days as 20 separate courses of treatment, when high carbohydrate intake (300 g for a minimum of 72 hours) and supportive measures were unsuccessful. Urinary ALA and PBG levels were collected as well as clinical signs and symptoms of AIP recorded.

Out of 20 treatment courses for acute attacks, there was a clinical response in 14. All patients had significant reductions in ALA and/or PBG levels after hemin treatment (p-value in the range from less than 0.001 to 0.05). In another study by Lamon et al.

5 seven patients with acute attacks of porphyria were administered 11 hemin courses (each course: 1 mg/kg every 24 hours for 3 to 13 days). Before and during hemin administration, patients were maintained on a 250-300 g/24H carbohydrate diet. Patients had elevated urinary ALA and PBG treatment and clinical evidence of an acute attack.

Chemical response of a decrease in ALA and PBG occurred in every patient (except one PBG value in one patient) when treatment lasted 5 days or longer (p<0.001).

Medicaid utilization & spend

📍 This exact package only: Medicaid data is reported per full 11-digit NDC — labeler, product and pack size — so every number here is for this package alone, not the drug overall. Other pack sizes report separately.
💊 Pharmacy benefit only: These are Medicaid outpatient pharmacy claims, billed by NDC. They exclude the medical benefit — clinic- or hospital-administered drugs billed under HCPCS J-codes — so drugs used mostly that way (e.g. Avastin, Lucentis, Keytruda) can look low or missing here. That’s expected, not an error.

💵 About the dollar figures: “reimbursed” is what Medicaid paid pharmacies before confidential manufacturer rebates, so the program’s real net cost is lower than these numbers. Fee-for-service and managed-care claims are combined unless split above. Source: CMS State Drug Utilization Data; per-100k rates use 2023 Census population estimates.

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 form printed on the packaging and shown on DailyMed is the one the FDA registered. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero and the dashes are dropped. The Identity section at the top of this page lists each form of this code.
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 Recordati Rare Diseases, Inc.. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
Recordati Rare Diseases, 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 J1640 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.
Where does this data come from?
Listing facts (marketing category, packager status, marketing dates) from the FDA openFDA NDC Directory; label availability from DailyMed; pricing coverage from CMS NADAC; equivalence scope from the FDA Orange Book.
