- Gadoxetic acid
- DrugBank Accession Number
- DB08884
- Background
-
Gadoxetic acid (gadoxetate) is a paramagnetic gadolinium-containing 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. It is marketed by Bayer HealthCare Pharmaceuticals and FDA approved on July 3, 2008.

-
Gadoxetate二钠is an amphipathic compound in which gadoxetate is hydrophillic and its moiety, the ethoxybenyzl group, is lipophillic. Consequently, gadoxetate disodium has a biphasic mode of action in which it first distributes into the extracellular space after bolus injection and then hepatocytes selectively takes up the drug.
- Mechanism of action
-
When gadoxetate disodium is placed in an external magnetic field, a large magnetic moment is produced. As a result, a magnetic field is induced around the tissue. The water protons in the vicinity are disrupted such that the change the proton density and spin characteristics are detected and visualized by a device.

- Volume of distribution
-
Total volume of distribution at steady state is 0.21 L/kg. Gadoxetate disodium cannot diffuse through the blood brain barrier. The two transporters that gadoxetate disodium can enter the hepatocyte through are OATP1B1 and OATP1B3. Gadoxetate disodium may also exit the heptaocyte and go back into sinusoidal space via active transport through multidrug resistance protein 3 and 4.
- Protein binding
-
<10% protein bound. Because it is more protein bound than other gadolinium-based contrast agents, gadoxetate disodium has increased T1 relaxivity. This results in an enhancement of the signal.
- Metabolism
-
Gadoxetate二钠is not metabolized.
- 路线的消除
-
Gadoxetate二钠is eliminated equally via urine and feces. Multidrug resistance protein 2 actively transports/excretes gadoxetate disodium into the bile.
- Half-life
-
Terminal elimination half-life, healthy subjects, adults = 0.91 - 0.95 hours
- Clearance
-
Clearance may be lower in older patients. Total serum clearance (CLtot) = 250 mL/min; Renal clearance (CLr) = 120 mL/min
