CARDIOGRAFIN vs CHOLOGRAFIN 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.
Iodipamide (cholografin sodium) is a radiographic contrast agent that opacifies the biliary ducts and gallbladder by being excreted into bile via the hepatic organic anion transporter (OATP) and then concentrated in the gallbladder. It absorbs X-rays due to its iodine content, allowing visualization of the biliary tree.
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.
2-3 mL of 30% solution intravenously over 1-2 minutes, repeated if necessary up to a total of 10 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).
Terminal elimination half-life is approximately 1-2 hours in patients with normal renal function. In severe renal impairment (CrCl < 30 mL/min), half-life may extend to 10-20 hours, requiring dose adjustment.
Primarily renal (glomerular filtration) with >90% of dose excreted unchanged in urine within 24 hours; less than 1% biliary/fecal; negligible metabolism.
Primarily renal excretion via glomerular filtration and tubular secretion. Approximately 70-80% of the dose is excreted unchanged in urine within 24 hours. Biliary excretion accounts for less than 10%, with fecal elimination minimal.
