Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Iothalamate meglumine is an ionic, high-osmolality radiopaque contrast agent that attenuates X-rays, allowing visualization of vascular structures and organs during radiographic procedures.
Iodinated radiocontrast agent; attenuates X-rays, providing vascular and tissue opacification.
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.
Intraarterial or intravenous administration; dose depends on procedure, age, weight, cardiac output, and clinical condition. Typical adult dose: 50-150 mL of 270 mg I/mL (50-80 mL for coronary arteriography, 30-50 mL for left ventriculography; up to 250 mL total for multiple injections).

Terminal elimination half-life is approximately 2 hours in patients with normal renal function; prolonged in renal impairment.
Terminal elimination half-life is approximately 1.5–2 hours in patients with normal renal function (creatinine clearance >60 mL/min). Prolonged in renal impairment, correlating with degree of kidney dysfunction.
Primarily renal excretion via glomerular filtration; >90% of administered dose eliminated unchanged in urine within 24 hours. Less than 1% biliary or fecal.
Renal excretion via glomerular filtration; >95% of administered dose eliminated unchanged in urine within 24 hours. Minimal biliary or fecal excretion (<1%).
