ULTRAVIST 370 vs VISIPAQUE 270
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Iodinated radiocontrast agent; attenuates X-rays, providing vascular and tissue opacification.
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.
Intraarterial or intravenous administration; dose depends on procedure, age, weight, cardiac output, and clinical condition. Typical adult dose: 50-150 mL of 270 mg I/mL (50-80 mL for coronary arteriography, 30-50 mL for left ventriculography; up to 250 mL total for multiple injections).

Terminal elimination half-life: 2 hours (normal renal function); prolonged to up to 36 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life is approximately 1.5–2 hours in patients with normal renal function (creatinine clearance >60 mL/min). Prolonged in renal impairment, correlating with degree of kidney dysfunction.
Renal: 95% unchanged within 24 hours via glomerular filtration; Biliary/Fecal: <5%; negligible biliary excretion.
Renal excretion via glomerular filtration; >95% of administered dose eliminated unchanged in urine within 24 hours. Minimal biliary or fecal excretion (<1%).
