Why two NDCs? The FDA registers this code as 50419-325-15 — a 5-3-2 layout, and that's what's printed on the package and shown on DailyMed. For insurance claims, every NDC is standardized to a uniform 11-digit 5-4-2 format by adding a zero to the product segment → 50419-0325-15. Same drug, same package — only the format differs.

Where does this data come from?
Data sourced from official FDA Structured Product Labeling (SPL) via DailyMedingredient classCode="IACT" elements from the exact product block matched by this NDC. Label-section narrative from DailyMed / the openFDA label index is shown separately when available.

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.

Price systemPer eachPer package
Retail pharmacies payNADAC · weekly Not in the retail survey — common for institutional, discontinued, or low-volume packs.
Medicaid paysCMS SDUD · 12 mo $14.03 $140.28 / 10 bottles
Medicare drug plans payPart D · quarterly No Part D plan price is available for this NDC in our data.
Medicare Part B allowsASP · A9585 $0.262 / A9585 unit
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.

The FDA lists approved generic versions of this medicine, but that does not always mean a pharmacy can get one today. Patent rules, launch agreements, supply and pricing can affect when generics actually arrive.

Where does this data come from?
Patents and exclusivity from the FDA Orange Book (small-molecule drugs), refreshed from public FDA data. Generic launch timing is an estimate, not a guarantee.

🗺️ 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 50419-0325-15, 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.
📅 Q1 2025 – Q4 2025 · 4 quarters of data
ⓘ The newest quarter is usually incomplete when first published; states restate recent quarters in later CMS releases, so the latest figures typically revise upward. State coverage-policy changes can also shift quarter-to-quarter totals.

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.
What does the discontinued status mean for this NDC?
The labeler reported a marketing end date (or the listing was delisted), so this specific package is no longer actively marketed. Remaining stock may still be dispensed for a time, and the NDC stays valid for historical records and claims — but data feeds (pricing, labeling) typically stop updating for it. Other package sizes or other manufacturers' versions of the same medication may still be marketed — see the equivalents section where available.
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 50419-325-15, 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: 50419-0325-15, written without dashes as 50419032515. 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 50419-0325-15, the first segment (50419) is the labeler code FDA assigned to Bayer HealthCare Pharmaceuticals Inc.; the middle segment (0325) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (15) identifies this exact package size and type. Together they name one specific package of one specific product.
Does this product come in other package sizes?
Yes — the FDA directory lists 14 other package presentations of this same product, including 3 vials (50419-0325-37), 5 bottles (50419-0325-14), 5 syringes (50419-0325-27). Each has its own NDC and its own page — see the package list near the top of this page.
Who lists this product with the FDA?
Bayer HealthCare 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 A9585 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.

🚨 Boxed Warning ~2 min read

WARNING: RISK ASSOCIATED WITH INTRATHECAL USE and NEPHROGENIC SYSTEMIC FIBROSIS Risk Associated with Intrathecal Use Intrathecal administration of gadolinium-based contrast agents (GBCAs) can cause serious adverse reactions including death, coma, encephalopathy, and seizures. GADAVIST is not approved for intrathecal use [see Warnings and Precautions (5.1) ]. Nephrogenic Systemic Fibrosis GBCAs increase the risk for nephrogenic systemic fibrosis (NSF) among patients with impaired elimination of the drugs.

Avoid use of GADAVIST in these patients unless the diagnostic information is essential and not available with non-contrasted MRI or other modalities. NSF may result in fatal or debilitating fibrosis affecting the skin, muscle and internal organs. The risk for NSF appears highest among patients with: Chronic, severe kidney disease (GFR < 30 mL/min/1.73m 2 ), or Acute kidney injury.

Screen patients for acute kidney injury and other conditions that may reduce renal function. For patients at risk for chronically reduced renal function (for example, age > 60 years, hypertension or diabetes), estimate the glomerular filtration rate (GFR) through laboratory testing. For patients at highest risk for NSF, do not exceed the recommended GADAVIST dose and allow a sufficient period of time for elimination of the drug from the body prior to any re-administration [see Warnings and Precautions (5.2) ].

WARNING: RISK ASSOCIATED WITH INTRATHECAL USE and NEPHROGENIC SYSTEMIC FIBROSIS See full prescribing information for complete boxed warning. Intrathecal administration of gadolinium-based contrast agents (GBCAs) can cause serious adverse reactions including death, coma, encephalopathy, and seizures. GADAVIST is not approved for intrathecal use.

( 5.1 ) GBCAs increase the risk for nephrogenic systemic fibrosis (NSF) among patients with impaired elimination of the drugs. Avoid use of GADAVIST in these patients unless the diagnostic information is essential and not available with non-contrasted MRI or other modalities. The risk for NSF appears highest among patients with: Chronic, severe kidney disease (GFR < 30 mL/min/1.73m 2 ), or Acute kidney injury.

Screen patients for acute kidney injury and other conditions that may reduce renal function. For patients at risk for chronically reduced renal function (for example, age >60 years, hypertension or diabetes), estimate the glomerular filtration rate (GFR) through laboratory testing. ( 5.2 )

⏱️ Dosage and Administration ~3 min read

2 DOSAGE AND ADMINISTRATION Recommended dose for adults and pediatric patients, including term neonates, is 0.1 mmol/kg actual body weight (equivalent to 0.1 mL/kg) administered by intravenous bolus injection. ( 2.1 , 2.2 ) See Full Prescribing Information for administration, imaging, and handling. ( 2.2 , 2.3 )

2.1Recommended Dose The recommended dose of GADAVIST for adult and pediatric patients, including term neonates, is 0.1 mmol/kg actual body weight (equivalent to 0.1 mL/kg) administered intravenously. For CMRI, the dose is divided into two separate, equal injections [see Dosage and Administration (2.2) ]. Refer to Table 1 for volumes to be administered for example body weights.

Table 1: Volume of GADAVIST for Example Body Weights Body Weight (kg) Volume to be Administered (mL) 2.5 0.25 5 0.5 10 1 15 1.5 20 2 25 2.5 30 3 35 3.5 40 4 45 4.5 50 5 60 6 70 7 80 8 90 9 100 10 110 11 120 12 130 13 140 14

2.2Administration and Imaging Instructions General GADAVIST is formulated at a higher concentration (1 mmol/mL) compared to certain other gadolinium-based contrast agents, resulting in a lower volume of administration [see Dosage and Administration (2.1) ]. GADAVIST is for intravenous use only and must not be administered intrathecally [see Warnings and Precautions (5.1) ] . Use aseptic technique when preparing and administering GADAVIST.

Visually inspect GADAVIST for particulate matter and discoloration prior to administration. Do not use the solution if it is discolored, if particulate matter is present, or if the container appears damaged. If solidification occurs due to cold exposure, bring GADAVIST to room temperature before use and inspect to ensure that the solution is clear and colorless to pale yellow.

Do not mix GADAVIST with other medications and do not administer GADAVIST in the same intravenous line simultaneously with other medications. MRI of the CNS in Adult and Pediatric Patients Including Term Neonates Administer GADAVIST as an intravenous injection, manually or by power injector, at a flow rate of approximately 2 mL/sec. Follow GADAVIST injection with a flush of 0.9% Sodium Chloride Injection to ensure complete administration of the contrast.

Post contrast MRI can commence immediately following contrast administration. MRI of the Breast in Adults Administer GADAVIST as an intravenous bolus by power injector, followed by a flush of 0.9% Sodium Chloride Injection to ensure complete administration of the contrast. Start image acquisition following GADAVIST administration and then repeat sequentially to determine peak intensity and wash-out.

MR Angiography in Adult and Pediatric Patients Including Term Neonates Image acquisition should coincide with peak arterial concentration, which varies among patients. For adults, administer GADAVIST as an intravenous injection by power injector, at a flow rate of approximately 1.5 mL/sec, followed by a 30 mL flush of 0.9% Sodium Chloride Injection at the same rate to ensure complete administration of the contrast. For pediatric patients including term neonates, administer GADAVIST as an intravenous injection by power injector or manually, followed by a flush of 0.9% Sodium Chloride Injection to ensure complete administration of the contrast.

Cardiac MRI in Adults Administer GADAVIST through a separate intravenous line in the contralateral arm if concomitantly providing a continuous infusion of a pharmacologic stress agent. Administer GADAVIST as two separate bolus injections: 0.05 mmol/kg actual body weight (equivalent to 0.05 mL/kg) at peak pharmacologic stress followed by 0.05 mmol/kg (equivalent to 0.05 mL/kg) at rest. Administer GADAVIST via a power injector at a flow rate of approximately 4 mL/sec and follow each injection with a 20 mL flush of 0.9% Sodium Chloride Injection at the same flow rate.

4 CONTRAINDICATIONS GADAVIST is contraindicated in patients with history of severe hypersensitivity reactions to GADAVIST [see Warnings and Precautions (5.3) ] . History of severe hypersensitivity reaction to GADAVIST ( 4 )

⚠️ Warnings and Cautions ~3 min read

5 WARNINGS AND PRECAUTIONS Hypersensitivity Reactions: Anaphylactic and other hypersensitivity reactions with cardiovascular, respiratory or cutaneous manifestations, ranging from mild to severe, including death, have occurred. Monitor patients closely during and after administration of GADAVIST. ( 5.3 ) Acute Respiratory Distress Syndrome: For patients demonstrating respiratory distress after administration, assess oxygen requirement and monitor for worsening respiratory function.

( 5.4 ) Gadolinium Retention: Gadolinium is retained for months or years in brain, bone, and other organs. ( 5.5 )

5.1Risk Associated with Intrathecal Use Intrathecal administration of GBCAs can cause serious adverse reactions including death, coma, encephalopathy, and seizures. The safety and effectiveness of GADAVIST have not been established with intrathecal use. GADAVIST is not approved for intrathecal use [see Dosage and Administration (2.2) ].

5.2Nephrogenic Systemic Fibrosis GBCAs increase the risk for nephrogenic systemic fibrosis (NSF) among patients with impaired elimination of the drugs. Avoid use of GADAVIST among these patients unless the diagnostic information is essential and not available with non-contrast MRI or other modalities. The GBCA-associated NSF risk appears highest for patients with chronic, severe kidney disease (GFR < 30 mL/min/1.73m 2 ) as well as patients with acute kidney injury.

The risk appears lower for patients with chronic, moderate kidney disease (GFR 30 to 59 mL/min/1.73m 2 ) and little, if any, for patients with chronic, mild kidney disease (GFR 60 to 89 mL/min/1.73m 2 ). NSF may result in fatal or debilitating fibrosis affecting the skin, muscle and internal organs. Report any diagnosis of NSF following GADAVIST administration to Bayer Healthcare (1-888-842-2937) or FDA (1-800-FDA-1088 or www.fda.gov/medwatch).

Screen patients for acute kidney injury and other conditions that may reduce renal function. Features of acute kidney injury consist of rapid (over hours to days) and usually reversible decrease in kidney function, commonly in the setting of surgery, severe infection, injury or drug-induced kidney toxicity. Serum creatinine levels and estimated GFR may not reliably assess renal function in the setting of acute kidney injury.

For patients at risk for chronically reduced renal function (for example, age > 60 years, diabetes mellitus or chronic hypertension), estimate the GFR through laboratory testing. Among the factors that may increase the risk for NSF are repeated or higher than recommended doses of a GBCA and degree of renal impairment at the time of exposure. Record the specific GBCA and the dose administered to a patient.

For patients at highest risk for NSF, do not exceed the recommended GADAVIST dose and allow a sufficient period of time for elimination of the drug prior to re-administration. For patients receiving hemodialysis, consider the prompt initiation of hemodialysis following the administration of a GBCA in order to enhance the contrast agent's elimination [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3) ] . The usefulness of hemodialysis in the prevention of NSF is unknown .

5.3Hypersensitivity Reactions Anaphylactic and other hypersensitivity reactions with cardiovascular, respiratory or cutaneous manifestations, ranging from mild to severe, have occurred following GADAVIST administration [see Adverse Reactions (6.1 , 6.2) ]. There have been reports of life-threatening and fatal outcomes from these adverse reactions. Most hypersensitivity reactions to GADAVIST have occurred within half an hour after administration.

Delayed reactions can occur up to several days after administration. Before GADAVIST administration, assess all patients for any history of a reaction to contrast media, bronchial asthma and/or allergic disorders. These patients may have an increased risk for a hypersensitivity reaction to GADAVIST.

6 ADVERSE REACTIONS The following clinically significant adverse reactions are discussed elsewhere in labeling: Nephrogenic Systemic Fibrosis [see Warnings and Precautions (5.2) ] Hypersensitivity reactions [see Contraindications (4) and Warnings and Precautions (5.3) ] Acute Respiratory Distress Syndrome [see Warnings and Precautions (5.4) ] Most common adverse reactions (incidence ≥ 0.5%) are headache, nausea, and dizziness ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Bayer HealthCare Pharmaceuticals Inc. at 1-888-842-2937 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch

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 clinical practice. The safety of GADAVIST was evaluated in 7,713 subjects (including 184 pediatric population, ages 0 to 17 years) who received GADAVIST in clinical trials. Approximately 52% of the subjects were male and the racial and ethnic distribution was 62% White, 28% Asian, 5% Hispanic or Latino, 2.5% Black or African American, and 2.5% other ethnic groups.

The average age was 56 years (range from 1 week to 93 years). Table 2 lists adverse reactions that occurred in ≥ 0.1% subjects who received GADAVIST. Table 2: Adverse Reactions Reported in ≥0.1% Subjects who Received GADAVIST in Clinical Trials Adverse Reaction GADAVIST n=7,713 Rate (%) Headache

Adverse Reactions in Pediatric Patients The frequency, type, and severity of adverse reactions observed in pediatric patients from the clinical studies were similar to adverse reactions in adults [ s ee Use in Specific Populations (8.4) ] .

6.2Postmarketing Experience The following additional adverse reactions have been identified during postmarketing use of GADAVIST or other GBCAs. Because these reactions are reported voluntarily from a population of uncertain size, it is not possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Cardiac Disorders: Cardiac arrest Gastrointestinal Disorders: Acute pancreatitis with onset within 48 hours after GBCA administration General Disorders and Administration Site Conditions: Fatigue, asthenia, pain syndromes, and heterogeneous clusters of symptoms in the neurological, cutaneous, and musculoskeletal systems with variable onset and duration after GBCA administration [see Warnings and Precautions (5.5) ] Immune System Disorders: Hypersensitivity reactions (anaphylactic shock, circulatory collapse, respiratory arrest, bronchospasm, cyanosis, oropharyngeal swelling, laryngeal edema, blood pressure increased, chest pain, angioedema, conjunctivitis, hyperhidrosis, cough, sneezing, burning sensation, and pallor) Renal Disorders: Nephrogenic systemic fibrosis Respiratory, Thoracic, and Mediastinal Disorders: Acute respiratory distress syndrome, pulmonary edema Skin Disorders: Gadolinium associated plaques

👥 Use in Specific Populations ~3 min read

8 USE IN SPECIFIC POPULATIONS Pregnancy: Use only if imaging is essential during pregnancy and cannot be delayed. ( 8.1 )

8.1Pregnancy Risk Summary GBCAs cross the placenta and result in fetal exposure. In human placental imaging studies, contrast was visualized in the placenta and fetal tissues after maternal GBCA administration. Based on animal studies, use of GBCAs during pregnancy may result in fetal gadolinium retention.

Published epidemiological studies on the association between GBCAs and adverse fetal outcomes have reported inconsistent findings and have important methodological limitations (see Data ) . In animal reproduction studies, although teratogenicity was not observed, embryolethality was observed in monkeys, rabbits and rats receiving intravenous gadobutrol during organogenesis at doses 8 times and above the recommended human dose. Retardation of embryonal development was observed in rabbits and rats receiving intravenous gadobutrol during organogenesis at doses 8 and 12 times, respectively, the recommended human dose (see Data ) .

Because of the potential risks of gadolinium to the fetus, use GADAVIST only if imaging is essential during pregnancy and cannot be delayed. The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes.

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and is 15% to 20%, respectively. Data Human Data Available data regarding exposure to GBCAs during pregnancy from published epidemiological studies are not sufficient to assess the risk of adverse fetal and neonatal effects that may be associated with GBCAs. A retrospective cohort study of over 1.4 million pregnancies in Ontario, Canada, comparing pregnant women who had a GBCA MRI to pregnant women who did not have an MRI, reported a higher occurrence of stillbirths and neonatal deaths in the group receiving GBCA MRI.

Limitations of this study include a lack of comparison with non-contrast MRI and lack of information about the maternal indication for MRI. Another retrospective cohort study of over 11 million pregnancies in the Medicaid database found no increased risk of fetal or neonatal death or Neonatal Intensive Care Unit admission when comparing pregnancies exposed to GBCA MRI versus non-contrast MRI. These two retrospective observational studies assessed a limited number of potential pregnancy outcomes and did not evaluate the full spectrum of potential fetal risk.

Animal Data Gadolinium Retention GBCAs administered to pregnant non-human primates (0.1 mmol/kg on gestational days 85 and 135) result in measurable gadolinium concentration in the offspring in bone, brain, skin, liver, kidney, and spleen for at least 7 months. GBCAs administered to pregnant mice (2 mmol/kg daily on gestational days 16 through 19) result in measurable gadolinium concentrations in the pups in bone, brain, kidney, liver, blood, muscle, and spleen at one month postnatal age. Reproductive Toxicology Embryolethality was observed when gadobutrol was administered intravenously to monkeys during organogenesis at doses 8 times the recommended single human dose (based on body surface area); gadobutrol was not maternally toxic or teratogenic at this dose.

Embryolethality and retardation of embryonal development also occurred in pregnant rats receiving maternally toxic doses of gadobutrol (≥ 7.5 mmol/kg body weight; equivalent to 12 times the human dose based on body surface area) and in pregnant rabbits (≥ 2.5 mmol/kg body weight; equivalent to 8 times the recommended human dose based on body surface area). In rabbits, this finding occurred without evidence of pronounced maternal toxicity and with minimal placental transfer (0.01% of the administered dose detected in the fetuses).

Because pregnant animals received repeated daily doses of…

🧒 Pediatric Use 205 words

8.4Pediatric Use The safety and effectiveness of GADAVIST have been established in pediatric patients, including term neonates, for use with MRI to detect and visualize areas with disrupted blood brain barrier and/or abnormal vascularity of the CNS and for use in MRA to evaluate known or suspected supra-aortic or renal artery disease. Use of GADAVIST for these indications is supported by adequate and well-controlled studies in adults and by additional imaging, pharmacokinetic, and safety data from two studies (i.e., Trials 1 and 2) in a total of 182 pediatric patients aged less than 18 years, including term neonates, with CNS and non-CNS lesions.

Trial 1 included 138 patients aged 2 to less than 18 years and Trial 2 included 44 patients aged less than 2 years [see Adverse Reactions (6.1) , Clinical Pharmacology (12.3) , and Clinical Studies (14.1 , 14.3) ]. The safety and effectiveness of GADAVIST have not been established in preterm neonates for any indication or in pediatric patients of any age for use with MRI to assess the presence and extent of malignant breast disease, or for use in CMRI to assess myocardial perfusion (stress, rest) and late gadolinium enhancement in patients with known or suspected coronary artery disease (CAD).

🧓 Geriatric Use 117 words

8.5Geriatric Use In clinical studies of GADAVIST, 1,377 patients were 65 years of age and over, while 104 patients were 80 years of age and over. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences between the elderly and younger patients. This drug is known to be excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function.

Because elderly patients are more likely to have decreased renal function, it may be useful to monitor renal function [see Warnings and Precautions (5.2) and Use in Specific Populations (8.6) ] .

🆘 Overdosage 41 words

10 OVERDOSAGE In the event of an overdose with GADAVIST, the substance can be removed by hemodialysis [see Clinical Pharmacology (12.3) ] . For additional overdose management recommendations, consider contacting the Poison Help line at 1-800-222-1222 or consulting a medical toxicologist.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Gadobutrol is a paramagnetic molecule (macrocyclic non-ionic complex of gadolinium) that develops a magnetic moment when placed in a magnetic field. The magnetic moment alters the relaxation rates of water protons in its vicinity in the body, leading to an increase in signal intensity (brightness) of tissues.

12.2Pharmacodynamics In MRI, visualization of normal and pathological tissue depends in part on variations in the radiofrequency signal intensity that occurs with: Differences in proton density Differences of the spin-lattice or longitudinal relaxation times (T 1 ) Differences in the spin-spin or transverse relaxation time (T 2 ) When placed in a magnetic field, gadobutrol shortens the T 1 and T 2 relaxation times in targeted tissues. The extent to which a contrast agent can affect the relaxation rate of tissue water (1/T 1 or 1/T 2 ) is termed relaxivity (r 1 or r 2 ).

The relaxivity of GBCAs is presented in Table 4. Table 4: Relaxivity (r 1 ) of GBCAs in Human Plasma at

4.1 Gadoxetate

6.9Compared to 0.5 molar gadolinium-based contrast agents, the higher concentration of GADAVIST results in half the volume of administration and a more compact contrast bolus injection. At the site of imaging, the relative height and width of the time intensity curve for GADAVIST varies as a function of imaging location and multiple patient, injection, and device-specific factors.

12.3Pharmacokinetics After intravenous administration of 0.1 mmol/kg GADAVIST, average plasma levels of gadobutrol are 0.59 mmol/L at 2 minutes after injection and 0.3 mmol/L at 60 minutes after injection, with an AUC of 1,072 µmol∙h/L. Values for further PK parameters are given in Table 5 below. Distribution After intravenous administration, gadobutrol is distributed in the extracellular space.

Gadobutrol does not display any particular protein binding. Following GBCA administration, gadolinium is present for months or years in brain, bone, skin, and other organs [see Warnings and Precautions (5.5) ] . Elimination The average elimination half-life (t 1/2 ) of gadobutrol is 1.8 hours .

Metabolism Gadobutrol is not metabolized. Excretion Gadobutrol is excreted in an unchanged form through the kidneys by glomerular filtration. In healthy subjects, renal clearance of gadobutrol is 1.1 to 1.7 mL/(min∙kg) and thus comparable to the renal clearance of inulin.

Within 2 hours after intravenous administration more than 50% and within 12 hours more than 90% of the given dose is eliminated via the urine. Extra-renal elimination is negligible. Specific Populations Geriatric Patients A single intravenous dose of 0.1 mmol/kg GADAVIST was administered to 15 elderly and 16 non-elderly subjects.

AUC was slightly higher (43%) and clearance slightly lower (31%) in elderly subjects as compared to non-elderly subjects [see Use in Specific Populations (8.5) ]. Pediatric Patients The pharmacokinetics of gadobutrol were evaluated in a total of 173 pediatric patients aged less than 18 years (including term neonates) who received a single intravenous dose of 0.1 mmol/kg of GADAVIST. Table 5 shows the pharmacokinetic parameters of gadobutrol by age group.

The pharmacokinetic profile of gadobutrol in pediatric patients is similar to that in adults, resulting in similar values for AUC, body weight normalized plasma clearance, as well as elimination half-life. Approximately 99% (median value) of the dose was recovered in urine within 6 hours (this information was derived from the 2 to less than 18 year-old age group).
