OMNIPAQUE 9 vs UROVIST SODIUM 300
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Iodinated contrast agent that attenuates X-rays, improving visualization of vascular structures and organs during imaging.
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.
Intravenous injection of 50-100 mL for contrast imaging, typically a single dose of 300 mg iodine/mL.

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.
Terminal elimination half-life is approximately 2 hours in patients with normal renal function (GFR >90 mL/min). In renal impairment, half-life may be prolonged up to 10 hours or more, correlating with decreased GFR.
Renal: >95% unchanged via glomerular filtration; fecal: <1%.
Primarily renal (glomerular filtration), with >90% of the administered dose excreted unchanged in urine within 24 hours. Biliary/fecal excretion is negligible (<5%).
