OMNIPAQUE 240 vs OMNIPAQUE 350
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Iodinated radiocontrast agent that attenuates X-rays due to high atomic number of iodine, enhancing vascular and tissue contrast during imaging procedures. It distributes in extracellular fluid and is excreted unchanged by glomerular filtration.
Radiopaque agent: iodine-containing contrast medium that attenuates X-rays, enhancing vascular and tissue contrast during imaging. Non-ionic, low-osmolar agent.
Intravenous administration: 50-200 mL (12-48 g iodine) of OMNIPAQUE 240 (240 mg iodine/mL) as a single dose, adjusted for procedure and patient size.
1-2 mL/kg IV up to 150 mL for CT; 30-50 mL IV for DSA; max 350 mL per procedure.

Terminal half-life approximately 1-2 hours in normal renal function; prolonged to 20-40 hours in severe renal impairment (CrCl <30 mL/min), necessitating dose adjustment
Terminal elimination half-life is approximately 1.5–2 hours in patients with normal renal function. May be prolonged in renal impairment.
Primarily renal (glomerular filtration, no tubular reabsorption); >95% excreted unchanged in urine within 24 hours; <5% biliary/fecal
Primarily renal excretion via glomerular filtration; >95% eliminated unchanged in urine within 24 hours. Biliary/fecal excretion is negligible (<1%).
