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 non-ionic contrast agent that attenuates X-rays due to its high iodine content (370 mg I/mL), enhancing vascular and tissue contrast during imaging. Does not bind to plasma proteins and has minimal pharmacological effects.
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.
Adult: IV administration of 370 mg iodine/mL at 1-1.5 mL/kg (370-555 mg I/kg) for CT; up to 300 mL total. Rate: 1-5 mL/sec.

Terminal elimination half-life is approximately 2 hours in patients with normal renal function; prolonged in renal impairment.
Terminal elimination half-life: 2 hours (normal renal function); prolonged to up to 36 hours in severe renal impairment (CrCl <30 mL/min).
Primarily renal excretion via glomerular filtration; >90% of administered dose eliminated unchanged in urine within 24 hours. Less than 1% biliary or fecal.
Renal: 95% unchanged within 24 hours via glomerular filtration; Biliary/Fecal: <5%; negligible biliary excretion.
