Gadobenate dimeglumineProduct ingredient for Gadobenic acid
- Name
- Gadobenate dimeglumine
- Drug Entry
- Gadobenic acid
Gadobenic acid, usually available in the salt form gadobenate dimeglumine, is a linear MRI gadolinium-based contrast agent (GBCA) used primarily for MR imaging of the liver.9 It differs from other GBCAs due to the benzene ring that confers weak protein binding, thus leading to an increased R1 and R2 relaxivity.8 As gadobenate dimeglumine is specifically taken up by hepatocytes and excreted through the biliary system, it is a useful contrast agent for liver MRI.3
Gadobenate dimeglumine was approved by the FDA in November 2004 under the brand name MultiHance.8
