GADAVIST vs GADOTERATE MEGLUMINE
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.
Gadoterate meglumine is a paramagnetic contrast agent that increases the relaxation rate of water protons in tissues, thereby enhancing image contrast in magnetic resonance imaging (MRI). It is a macrocyclic gadolinium-based contrast agent (GBCA) with high thermodynamic stability and kinetic inertness, reducing the risk of gadolinium dissociation.
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) intravenously as a single bolus injection.

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 elimination half-life approximately 1.5–2 hours in patients with normal renal function; prolonged in renal impairment (up to 12–34 hours in severe impairment).
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.
Primarily renal (99% excreted unchanged in urine within 24 hours); biliary/fecal elimination negligible (<1%).
