CARDIOGRAFIN vs SCANLUX-300
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.
SCANLUX-300 (gadoxetate disodium) is a hepatobiliary MRI contrast agent that shortens T1 relaxation time, enhancing signal intensity in tissues. It is taken up by hepatocytes via OATP1B1/1B3 transporters and excreted into bile via MRP2, allowing both dynamic and hepatobiliary phase 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.
30 mg/m² IV over 1 hour every 4 weeks.

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 is 3.5 hours (range 2.8–4.5 h); may be prolonged in hepatic impairment (up to 7 h).
Primarily renal (glomerular filtration) with >90% of dose excreted unchanged in urine within 24 hours; less than 1% biliary/fecal; negligible metabolism.
Renal excretion of unchanged drug accounts for approximately 30% of the administered dose; fecal/biliary elimination accounts for about 60% (via hepatobiliary secretion into feces); minimal excretion via other routes.
