DIATRIZOATE MEGLUMINE AND DIATRIZOATE SODIUM vs ULTRAVIST 370
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 non-ionic contrast agent that attenuates X-rays due to its high iodine content (370 mg I/mL), enhancing vascular and tissue contrast during imaging. Does not bind to plasma proteins and has minimal pharmacological effects.
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.
Adult: IV administration of 370 mg iodine/mL at 1-1.5 mL/kg (370-555 mg I/kg) for CT; up to 300 mL total. Rate: 1-5 mL/sec.

1-2 hours in normal renal function; prolonged in renal impairment (up to 20-30 hours in severe impairment)
Terminal elimination half-life: 2 hours (normal renal function); prolonged to up to 36 hours in severe renal impairment (CrCl <30 mL/min).
Renal: >95% unchanged via glomerular filtration; biliary/fecal: <5%
Renal: 95% unchanged within 24 hours via glomerular filtration; Biliary/Fecal: <5%; negligible biliary excretion.
