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.
RENOGRAFIN-60 (diatrizoate meglumine and diatrizoate sodium) is an ionic, high-osmolality, iodinated contrast agent. It enhances radiographic contrast by absorbing X-rays due to the high atomic number of iodine. It distributes into the intravascular space and is excreted primarily by the kidneys via glomerular filtration without significant tubular reabsorption or secretion.
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.
Intravenous: 50-100 mL of a 60% solution as a single dose for CT or angiography. Intra-arterial: 5-50 mL depending on vessel size. Maximum total dose: 3 mL/kg.

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: 1-2 hours in normal renal function. Prolonged in renal impairment: up to 50 hours. Clinically significant for timing of contrast imaging and risk of contrast-induced nephropathy.
Primarily renal (glomerular filtration): >95% of iodinated contrast is excreted unchanged in urine within 24 hours; <5% fecal or biliary.
Renal: 95-100% (glomerular filtration, no tubular reabsorption). Biliary/Fecal: negligible.
