GADAVIST vs GADOTERIDOL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Gadovist (gadobutrol) is a macrocyclic gadolinium-based contrast agent (GBCA) that enhances MRI signal intensity by shortening T1 relaxation time in tissues with altered vascularity or blood-brain barrier integrity.
Gadoteridol is a paramagnetic gadolinium-based contrast agent that increases signal intensity in T1-weighted magnetic resonance imaging by shortening the T1 relaxation time of protons in water molecules. It distributes in the extracellular fluid compartment and does not cross the intact blood-brain barrier, thus enhancing imaging in areas of disrupted barrier or abnormal vascularity.
0.1 mmol/kg (0.2 mL/kg) IV bolus; maximum dose 0.3 mmol/kg per imaging session.
0.2 mL/kg (0.1 mmol/kg) IV bolus, max 20 mL per dose; additional doses up to 0.4 mL/kg may be given within 30 minutes if needed.

Plasma terminal elimination half-life is approximately 1.5 hours in patients with normal renal function (GFR >60 mL/min/1.73m²). In renal impairment (GFR <30 mL/min/1.73m²), half-life extends to 10-15 hours; in end-stage renal disease, half-life may exceed 30 hours, necessitating adjustment of imaging timing.
Terminal half-life 1.5-2 hours in normal renal function; prolonged to 10-18 hours in moderate renal impairment (CrCl 30-60 mL/min) and up to 30 hours in severe renal impairment (CrCl <30 mL/min).
Primarily renal; approximately 95% of administered dose excreted unchanged in urine within 72 hours, with 85% eliminated within 6 hours. Less than 1% excreted in feces.
Renal: >95% unchanged via glomerular filtration. Biliary/fecal: <5%.
