NameGadofosveset trisodium
Accession NumberDB06705
TypeSmall Molecule
DescriptionGadofosveset trisodium is an intravenous contrast agent used with magnetic resonance angiography(MRA), which is a non-invasive way of imaging blood vessels. The agent allows for the vascular system to be imaged more clearly by the MRA. In this way, gadofosveset trisodium is used to help diagnose certain disorders of the heart and blood vessels.

IndicationGadofosveset trisodium is indicated for use as a contrast agent in magnetic resonance angiography (MRA) to evaluate aortoiliac occlusive disease (AIOD) in adults with known or suspected peripheral vascular disease.
PharmacodynamicsGadofosveset causes signal enhancement by shortening the T1 of water molecules that interact with it. The contrast agent complex's rotation rate is the primary factor determining the magnitude of relaxation enhancement. This relaxation enhancement increase only occurs when bound to human serum albumin.
Mechanism of actionGadofosveset binds reversibly to endogenous serum albumin resulting in longer vascular residence time than non-protein binding contrast agents. The binding to serum albumin also increases the magnetic resonance relaxivity of gadofosveset and decreases the relaxation time (Tl) of water protons resulting in an increase in signal intensity (brightness) of blood.

Protein binding80-90%

Gadofosveset does not undergo measurable metabolism.

Route of eliminationGadofosveset is eliminated primarily in the urine with approximately 83.5% of an injected dose excreted in the urine over 14 days. Ninety-four percent (94%) of urinary excretion occurs in the first 72 hours. A small portion of gadofosveset dose is recovered in feces (approximately 4.7%).
Half life18.5 hours

6.57 ± 0.97 mL/h/kg following the administration of 0.03 mmol/kg.

ToxicityGadolinium-based contrast agents increase the risk for nephrogenic systemic fibrosis (NSF) in patients with acute or chronic severe renal insufficiency (glomerular filtration rate < 30 mL/min/1.73m²).

Serum albumin, the main protein of plasma, has a good binding capacity for water, Ca(2+), Na(+), K(+), fatty acids, hormones, bilirubin and drugs. Its main function is the regulation of the colloidal osmotic pressure of blood. Major zinc transporter in plasma, typically binds about 80% of all plasma zinc.
