CARDIOGRAFIN vs UROVIST MEGLUMINE DIU/CT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cardiografin is an ionic, high-osmolar iodinated contrast agent used for radiographic imaging. It enhances contrast by attenuating X-rays, primarily due to the iodine content. It distributes in the extracellular space and is excreted unchanged by glomerular filtration.
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: 50-100 mL of CARDIOGRAFIN (diatrizoate meglumine and diatrizoate sodium) 76% intravenously as a bolus or rapid infusion. For cardiac ventriculography, 40-50 mL into the left ventricle. For coronary arteriography, 5-10 mL selective injection per artery.
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). May be prolonged to >20 hours in severe renal impairment (e.g., 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).
Primarily renal (glomerular filtration) with >90% of dose excreted unchanged in urine within 24 hours; less than 1% biliary/fecal; negligible metabolism.
Renal: >95% unchanged within 24 hours by glomerular filtration. Biliary/fecal: <5%.
