Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Iodinated contrast agent that attenuates X-rays, providing vascular and tissue opacification by increasing the density of blood vessels and organs.
Nonionic iodinated contrast medium that attenuates X-rays is excreted unchanged in urine; increases density of blood vessels and tissues to enhance radiological visualization.
Intravenous: 1-2 mL/kg (300 mg I/mL) for contrast-enhanced CT; intra-arterial: 5-80 mL per injection depending on procedure; maximum total dose 4 mL/kg.
Intravenous bolus injection: 0.5 mL/kg to 1 mL/kg of Osnovist 240 (240 mg iodine/mL) for CT enhancement, up to a maximum of 150 mL per dose.

The terminal elimination half-life of iohexol in patients with normal renal function (creatinine clearance > 90 mL/min) is approximately 1.5 to 2 hours. In patients with renal impairment, the half-life is significantly prolonged (up to 30 hours or more in severe renal failure), necessitating dose adjustment and careful monitoring.
Terminal elimination half-life approximately 2 hours (range 1.5–4 hours) in patients with normal renal function; prolonged in renal impairment proportional to creatinine clearance.
Omnipaque 300 (iohexol) is primarily eliminated unchanged by the kidneys via glomerular filtration. Renal excretion accounts for >95% of the administered dose within 24 hours in patients with normal renal function. Fecal excretion is negligible (<1%). Billiary excretion is minimal, with less than 0.1% recovered in bile or feces.
Primarily renal (glomerular filtration); >95% of administered dose excreted unchanged in urine within 24 hours. Negligible biliary/fecal elimination (<5%).
