GASTROVIST vs RENOVIST
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.
RENOVIST is a radiocontrast agent that enhances imaging by attenuating X-rays due to its iodine content. It acts by increasing the density of blood vessels and tissues, improving contrast in radiographic studies.
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.
0.5-1 mg/kg intravenously daily

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 half-life: 12 hours; in renal impairment (CrCl <30 mL/min) prolonged to 24-36 hours; dose adjustment required
Primarily renal (glomerular filtration): >95% of iodinated contrast is excreted unchanged in urine within 24 hours; <5% fecal or biliary.
Renal: 70% as unchanged drug; fecal: 20% as metabolites; biliary: 10%
