CARDIOGRAFIN vs CONRAY
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.
Iothalamate meglumine is an ionic, high-osmolality radiopaque contrast agent that attenuates X-rays, allowing visualization of vascular structures and organs during radiographic procedures.
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: 20-60 mL for CT enhancement; intra-arterial: 5-80 mL per injection; concentration 282 mgI/mL (iothalamate meglumine). Dose based on procedure, body weight, and renal function.

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 2 hours in patients with normal renal function; prolonged in renal impairment.
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; >90% of administered dose eliminated unchanged in urine within 24 hours. Less than 1% biliary or fecal.
