CARDIOGRAFIN vs CONRAY 43
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.
Iodinated contrast agent that attenuates X-rays, enhancing vascular and tissue contrast during imaging.
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: 0.5-1.0 mL/kg (20-43 mg I/kg) for CT; intra-arterial: 5-15 mL for selective studies; maximum single dose 150 mL.

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).
2 hours (normal renal function); prolonged to 20-40 hours in severe renal impairment (CrCl <10 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: >90% via glomerular filtration; unchanged drug. Biliary: <1%. Fecal: negligible.
