- Drug Entry
- Gadoxetic acid
Gadoxetic acid (gadoxetate) is a paramagnetic gadolinium-containing ionic linear contrast agent in which its salt form, gadoxetate disodium, is used for intravenous injection. Ethoxybenzyl diethylenetriaminepentaacetic acid is the moiety that chelates with a gadolinium ion and forms a stable complex with it to make up the drug.4 Gadoxetate is a unique gadolinium-based contrasting agent (GBCA) with both dynamic phase and hepatobiliary phase and thus has different pharmacokinetic and pharmacodynamic properties compared to other GBCAs.2 Since gadoxetate uptake is mediated by organic anion-transporting polypeptides (OATPs) and liver tumor cells lack OATPs, liver tumors show a lack of contrast of enhancement and therefore heightening the liver parenchyma-liver tumours contrast.2
Gadoxetic acid, under the form gadoxetate disodium, is marketed by Bayer HealthCare Pharmaceuticals under the brand name EOVIST and FDA approved in 2008.3
