OMNIPAQUE 180 vs UROVIST CYSTO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Iodinated contrast agent that radiates X-rays due to high iodine content, attenuating X-ray beams and enhancing vascular/tissue contrast.
Urovist Cysto is a radiocontrast agent containing diatrizoate meglumine and diatrizoate sodium. It provides radiographic visualization of the urinary tract by attenuating X-rays due to its iodine content. It is not systemically absorbed when used intravesically; local contrast enhancement occurs through physical properties.
Intravenous: 50-200 mL of 180 mgI/mL (9-36 g iodine) administered as a bolus or infusion, depending on imaging procedure and patient size; typical CT dose: 100-150 mL.
Instillation of 50 mL of a 0.3% solution intravesically, retained for 10 minutes, for cystography.

Terminal elimination half-life: 1-2 hours in patients with normal renal function; prolonged in renal impairment (up to 30-40 hours in severe impairment)
Terminal elimination half-life is approximately 2 hours in patients with normal renal function; may be prolonged in renal impairment.
Renal: >95% unchanged by glomerular filtration within 24 hours; Biliary/Fecal: <5%
Primarily renal excretion as unchanged drug (approximately 85-90% within 24 hours); minor biliary/fecal elimination (<5%).
