CARDIOGRAFIN vs DIATRIZOATE-60
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.
Diatrizoate is an ionic, monomeric, high-osmolar iodinated contrast agent that absorbs X-rays due to its iodine content, enhancing radiographic imaging by attenuating X-ray beams. It distributes in the extracellular fluid and is excreted unchanged by glomerular filtration.
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.
1-2 mL/kg IV bolus up to 150 mL total for contrast-enhanced CT; repeat doses may be given based on imaging needs.

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 half-life approximately 1-2 hours in patients with normal renal function. Prolonged in renal impairment (up to 20-30 hours in anuria).
Primarily renal (glomerular filtration) with >90% of dose excreted unchanged in urine within 24 hours; less than 1% biliary/fecal; negligible metabolism.
Primarily renal (glomerular filtration); >95% excreted unchanged in urine within 24 hours. Negligible biliary or fecal elimination.
