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 nonionic contrast agent that attenuates X-rays, enhancing vascular and tissue contrast. Its iodine content (350 mg/mL) provides radiopacity, while low osmolality reduces adverse hemodynamic 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.
Omnipaque 9 (iohexol 9 mg I/mL) is administered intravenously. For CT enhancement, typical adult dose is 50-100 mL (450-900 mg I) by slow IV injection.

Terminal elimination half-life is approximately 2 hours in patients with normal renal function; prolonged in renal impairment.
Terminal elimination half-life: 1–2 hours in patients with normal renal function; prolonged to >24 hours in severe renal impairment (CrCl <30 mL/min), necessitating dose adjustment.
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 via glomerular filtration; fecal: <1%.
