GASTROVIST vs MD-76
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.
MD-76 is a contrast agent that contains iodine, which attenuates X-rays, thereby enhancing the contrast between vascular structures and surrounding tissues. It distributes in the extracellular fluid compartment and is excreted unchanged by glomerular filtration.
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.
IV: 50-100 mL per dose, administered as a bolus or infusion, not to exceed 3 mL/kg total dose.

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: 1.5–2 hours; prolonged in renal impairment (up to 20 hours in anuria); clinical context: allows rapid elimination, suitable for diagnostic imaging
Primarily renal (glomerular filtration): >95% of iodinated contrast is excreted unchanged in urine within 24 hours; <5% fecal or biliary.
Renal: >95% unchanged via glomerular filtration; biliary/fecal: <5%
