DIATRIZOATE MEGLUMINE AND DIATRIZOATE SODIUM vs OMNIPAQUE 240
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Radiopaque contrast agent that attenuates X-rays, providing visualization of vascular and urinary structures. It is a high-osmolality ionic dimer that distributes in extracellular fluid and is excreted renally.
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.
Intra-arterial or intravenous administration; adult dose varies by procedure: for intravenous urography, 50-100 mL of 60% solution; for CT enhancement, 100-150 mL of 60% solution; maximum total dose 4.2 g iodine/kg body weight.
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 hours in normal renal function; prolonged in renal impairment (up to 20-30 hours in severe impairment)
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
Renal: >95% unchanged via glomerular filtration; biliary/fecal: <5%
Primarily renal (glomerular filtration, no tubular reabsorption); >95% excreted unchanged in urine within 24 hours; <5% biliary/fecal
