CARDIOGRAFIN vs DIATRIZOATE MEGLUMINE AND DIATRIZOATE SODIUM
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.
Radiopaque contrast agent that attenuates X-rays, providing visualization of vascular and urinary structures. It is a high-osmolality ionic dimer that distributes in extracellular fluid and is excreted renally.
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.
Intra-arterial or intravenous administration; adult dose varies by procedure: for intravenous urography, 50-100 mL of 60% solution; for CT enhancement, 100-150 mL of 60% solution; maximum total dose 4.2 g iodine/kg body weight.

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).
1-2 hours in normal renal function; prolonged in renal impairment (up to 20-30 hours in severe impairment)
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 via glomerular filtration; biliary/fecal: <5%
