A medication used during MRI tests of the brain to detect injuries and blood vessel damages.


A contrast agent used during diagnostic procedures to visualize disrupted areas of blood brain barrier (BBB) and/or abnormal vascularity of the central nervous system.


Intravenous gadobutrol is a second-generation extracellular non-ionic macrocyclic GBCA (gadolinium-based contrast agent) used in magnetic resonance imaging (MRI) in adults and children older than 2 years of age. It may help visualize and detect vascular abnormalities in the blood brain barrier (BBB) and central nervous system (CNS).

In patients with impaired renal function, gadolinium based contrast agents increase the risk of nephrogenic systemic fibrosis (NSF). A physician should be contacted if symptoms of NSF are encountered, such as dark or red patches on the skin; stiffness in joints; trouble moving, bending or straightening arms, hands, legs or feet; burning, itching, swelling, scaling, hardening and tightening of skin; pain in hip bones or ribs; or muscle weakness.

Common adverse reactions that may be experienced include headache, nausea, feeling hot, abnormal taste, and warmth, burning or pain local to the injection site.

General precautions should be taken in patients who are pregnant or breastfeeding, or who have a history of allergic reaction to contrast media, bronchial asthma or an allergic respiratory disorder.



For diagnostic use only. Indicated for adults and children age 2 and over for contrast enhancement during cranial and spinal MRI, and for contrast-enhanced magnetic resonance angiography (CE-MRA). Gadobutrol is particularly suited for the detection of very small lesions and for the visualization of... Read more


Even at low concentrations Gadobutrol can lead to distinct shortening of relaxation times of protons in plasma. At physiological conditions (pH=7, temperature=37°C), and 1.5T, the relaxivity (r1) is 5.2L/(mmol·sec) based on the relaxation times (T1), while the relativity (r2) is 6.1L/(mmol·sec) base...

Mechanism of action

MRI tissue visualization is dependent, in part, on variations in intensity of radiofrequency signals which occur due to differences in proton density, differences of the spin-lattice or longitudinal relaxation times (T1), and differences in the spin-spin or transverse relaxation times (T2).

With normal renal function, the AUC is 1.1 ± 0.1 mmol·h/L.

Protein binding

No particular protein binding is displayed.

Volume of distribution

Rapid distribution to extracellular space occurs after intravenous administration.After a dose of 0.1mmol/kg body weight, an average plasma level of 0.59 mmol/L was measured 2 minutes post injection, and 0.3mmol/L 60 minutes post injection.


In healthy subjects, renal clearance is 1.1 - 1.7mL/(min·kg).Within 2 hours of intravenous injection more than 50% is eliminated via the urine. Within 12 hours more than 90% of the given dose is eliminated.Clearance was observed to be slightly lower in elderly subjects, when using a 0.1mmol/kg dose.... Read more

Half life

1.81 hours (1.33-2.13 hours).

Route of elimination

Excreted unchanged via glomerular filtration by the kidneys.
Extrarenal elimination is negligible.


Lethality was observed in rodents after a single intravenous administration of 20 mmol/kg. This represents a dose of at least 2 orders of magnitude
higher than the standard single diagnostic dose in humans (0.1 mmol/kg).

No carcinogenicity studies have been conducted.

No mutagenesis was obse... Read more
