ULTRAVIST 370 vs UROVIST MEGLUMINE DIU/CT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Iodinated non-ionic contrast agent that attenuates X-rays due to its high iodine content (370 mg I/mL), enhancing vascular and tissue contrast during imaging. Does not bind to plasma proteins and has minimal pharmacological effects.
Urovist Meglumine DIU/CT is a contrast agent containing meglumine diatrizoate, an ionic monomeric iodinated radiopaque medium. It attenuates X-rays, enhancing vascular and tissue contrast during imaging. The diatrizoate ion increases plasma osmolality, potentially causing vasodilation and hemodynamic effects.
Adult: IV administration of 370 mg iodine/mL at 1-1.5 mL/kg (370-555 mg I/kg) for CT; up to 300 mL total. Rate: 1-5 mL/sec.
Intravenous administration: 100-200 mL of a 30% solution (containing 30% meglumine diatrizoate) infused over 10-30 minutes for CT imaging. Repeated doses may be given up to a maximum total dose equivalent to 4.0 mL/kg.

Terminal elimination half-life: 2 hours (normal renal function); prolonged to up to 36 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life 1–2 hours in patients with normal renal function. Prolonged to >20 hours with severe renal impairment (CrCl <30 mL/min).
Renal: 95% unchanged within 24 hours via glomerular filtration; Biliary/Fecal: <5%; negligible biliary excretion.
