Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Gastrovist (diatrizoate meglumine) is a iodinated radiographic contrast agent that attenuates X-rays, enhancing visualization of the gastrointestinal tract. It acts as a hyperosmolar agent, drawing fluid into the bowel lumen and providing positive contrast for imaging.
Iopamidol is a nonionic, water-soluble iodinated radiographic contrast agent that attenuates X-rays by increasing the density of tissues, thereby enhancing vascular and tissue contrast during imaging procedures.
Oral: 50-100 mL of a 30% w/v solution (300 mg iodine/mL) administered orally 30-60 minutes before imaging. Repeat dose if necessary for adequate visualization. Rectal: 100-200 mL of a 30% w/v solution as enema for CT colonography.
Intravascular administration: 1-2 mL/kg (200 mg I/mL) intravenously, up to a maximum of 150 mL per diagnostic procedure. Intraarterial administration: varies by procedure; typical 5-60 mL per injection.

Terminal elimination half-life is approximately 2 hours in patients with normal renal function (creatinine clearance >90 mL/min); prolonged to >20 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life approximately 2 hours (range 1.5-2.5 hours) in patients with normal renal function; prolonged in renal impairment.
Primarily renal (glomerular filtration): >95% of iodinated contrast is excreted unchanged in urine within 24 hours; <5% fecal or biliary.
Primarily renal (99% unchanged in urine within 24 hours). Biliary/fecal excretion <1%.
