GASTROVIST vs HYPAQUE-CYSTO
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.
HYPAQUE-CYSTO (diatrizoate meglumine) is a radiopaque contrast agent that absorbs x-rays, providing contrast in radiographic imaging. It acts as an iodinated contrast medium.
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.
Intravesical instillation: 100-300 mL of 30% solution for retrograde cystourethrography; single administration.

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: 1.5–2.5 hours (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.
Renal excretion via glomerular filtration: >95% unchanged within 24 hours. Fecal excretion: <5%.
