Identification
- Summary
Gadoteridol is a gadolinium-based contrast agent (GBCA) used with contrasted magnetic resonance imaging (MRI) to detect and visualize lesions and abnormal vascularity.
- Brand Names
- Prohance
- Generic Name
- Gadoteridol
- DrugBank Accession Number
- DB00597
- Background
Gadoteridol is a macrocyclic nonionic gadolinium that provides contrast enhancement of the brain, spine, and surrounding tissues, resulting in improved visualization (compared with unenhanced MRI) of lesions with abnormal vascularity or those thought to disrupt the normal blood-brain barrier.1,2,4 It was 1 of the 3 macrocyclic gadolinium-based contrast agents (GBCAs) that was mandated by the EMA to replace linear gadolinium-based contrast agents due to concerns about retained gadolinium in the brain.1
Initially approved by the FDA in 1992, gadoteridol received additional approval in 2020 for use in pediatric patients less than 2 years old.5

Pharmacology
- Indication
Gadoteridol is indicated for use with magnetic resonance imaging (MRI) in order to visualize lesions with disrupted blood-brain barrier and/or abnormal vascularity in the brain, spine, and associated tissues in adult and pediatric patients, including term neonates.4 It is also indicated for visualization of lesions in the head and neck in adult patients.4

- Pharmacodynamics
Gadoteridol affects proton relaxation times and consequently the MR signal. Signal intensity is affected by the dose and relaxivity of the gadoteridol molecule. Consistently, for all gadolinium-based contrast agents, the relaxivity of gadoteridol decreases with the increase of the magnetic field strength used in clinical MRI (0.2 –3.0T).4
Disruption of the blood-brain barrier or abnormal vascularity allows the accumulation of gadoteridol in lesions such as neoplasms, abscesses, and subacute infarcts. The pharmacokinetics of gadoteridol in various lesions is not known.4
- Mechanism of action
Gadoteridol is a paramagnetic agent and, as such, develops a magnetic moment when placed in a magnetic field. The relatively large magnetic moment produced by the paramagnetic agent results in a relatively large local magnetic field, which can enhance the relaxation rates of water protons in the vicinity of the paramagnetic agent.4
In MRI, visualization of normal and pathologic brain tissue depends, in part, on variations in the radiofrequency signal intensity that occur with: 1) differences in proton density; 2) differences of the spinlattice or longitudinal relaxation times (T1); and 3) differences in the spin-spin or transverse relaxation time (T2). When placed in a magnetic field, gadoteridol decreases T1 relaxation times in the target tissues. At recommended doses, the effect is observed with greatest sensitivity in the T1-weighted sequences.4
- Absorption
From population PK model of pediatric subjects receiving a single intravenous dose of 0.1 mmol/kg of gadoteridol, the mean Cmax was 0.66 ± 0.21 mmol/L in pediatric subjects 2 years to 6 years of age, 0.58 ± 0.06 mmol/L in pediatric subjects 6 years to 12 years of age, and 0.68 ± 0.12 mmol/L in adolescent subjects older than 12 years. The mean AUC0-∞ was 0.74 ± 0.20 mmol/Lh in pediatric subjects 2 years to 6 years of age, 0.74 ± 0.09 mmol/Lh in pediatric subjects 6 years to 12 years of age, and 0.98 ± 0.09 mmol/L*h in adolescent subjects older than 12 years of age. Pharmacokinetic simulations indicate similar half-life, AUC, and Cmax values for ProHance in pediatric subjects less than 2 years of age when compared to those reported for adults.4
- Volume of distribution
The plasma distribution volume (mean ± SD) for the non-renally impaired adults was 0.205 ± 0.025 L/kg.Following GBCA administration, gadolinium is present for months or years in the brain, bone, skin, and other organs. 4
- Protein binding
It is unknown if protein binding of gadoteridol occurs in vivo.4
- Metabolism
It is unknown if biotransformation or decomposition of gadoteridol occurs in vivo.4
- Route of elimination
Gadoteridol is eliminated in the urine with 94.4 ± 4.8% (mean ± SD) of the dose excreted within 24 hours post-injection. Over 80% of the dose was recovered in urine for pediatric subjects after 10 hours.4
In patients with moderately and severely impaired renal function about 97% and 76% of the administered dose was recovered in the urine within 7 days and 14 days, respectively.4
- Half-life
The elimination half-life (mean ± SD) is about 1.57 ± 0.08 hours.4
From population PK model of pediatric subjects receiving a single intravenous dose of 0.1 mmol/kg of gadoteridol, the mean distribution half-life (t1/2,alpha) was 0.14 ± 0.04 hours in pediatric subjects 2 years to 6 years of age, 0.18 ± 0.07 hours in pediatric subjects 6 years to 12 years of age, and 0.20 ± 0.07 hours in adolescent subjects older than 12 years of age. The mean elimination half-life (t1/2,beta) was 1.32 ± 0.006 hours in pediatric subjects 2 years to 6 years, 1.32 ± 0.07 hours in pediatric subjects 6 years to 12 years of age, and 1.61 ± 0.19 hours in adolescent subjects older than 12 years of age. Pharmacokinetic simulations indicate similar half-life values for gadoteridol in pediatric subjects less than 2 years of age when compared to those reported for adults.4
In patients with impaired renal function, the serum half-life of gadoteridol is prolonged. After intravenous injection of 0.1 mmol/kg, the elimination half-life of gadoteridol was 10.65 ± 0.06 hours in mild to moderately impaired patients (creatinine clearance 30 to 60 mL/min) and 9.10±0.26 hours in severely impaired patients not on dialysis (creatinine clearance 10 to 30 mL/min).4
- Clearance
The renal and plasma clearance rates (1.41 ± 0.33 mL/ min/kg and 1.50 ± 0.35 mL/ min/kg, respectively) of gadoteridol are essentially identical, indicating no alteration in elimination kinetics on passage through the kidneys and that the drug is essentially cleared through the kidney.4
The mean serum clearance of gadoteridol in patients with normal renal function was 116.14 ± 26.77 mL/min, compared to 37.2 ± 16.4 mL/min in patients with mild to moderate renal impairment and 16.0 ± 3.0 mL/min in patients with severe renal impairment.4

- Toxicity
Gadolinium-based contrast agents (GBCAs) cross the placenta and result in fetal exposure and gadolinium retention. The human data on the association between GBCAs and adverse fetal outcomes are limited and inconclusive. Because of the potential risks of gadolinium to the fetus, use gadoteridol only if imaging is essential during pregnancy and cannot be delayed.4
In animal reproduction studies in rats, gadoteridol doubled the incidence of post-implantation loss at up to 16 times the recommended human dose (RHD). There were no adverse developmental effects observed in rabbits with intravenous administration of gadoteridol during organogenesis at doses up to 19 times the recommended human dose of 0.1 mmol/kg.4
Clinical consequences of overdose with gadoteridol have not been reported. The safety of gadoteridol has been tested in clinical studies using doses up to 0.3 mmol/kg and no clinical consequences related to increasing dose have been observed to date. Gadoteridol can be removed by hemodialysis.4
No animal studies have been performed to evaluate the carcinogenic potential of gadoteridol.4
No changes in reproductive performance and outcome of pregnancy were caused in rats and rabbits by daily intravenous administration of gadoteridol to parent animals before and during gestation up to 1.5 mmol/kg/day (15 times the recommended human dose).4
Gadoteridol did not demonstrate genotoxic activity in: bacterial reverse mutation assays using Salmonella typhimurium and Escherichia coli; a mouse lymphoma forward mutation assay; an in vitro cytogenetic assay measuring chromosomal aberration frequencies in Chinese hamster ovary cells; and an in vivo mouse micronucleus assay at intravenous doses up to 5.0 mmol/kg.4
