Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Iodinated contrast agent that attenuates X-rays, providing vascular and tissue opacification by increasing the density of blood vessels and organs.
Barium sulfate is a radiopaque agent that coats the mucosal surfaces of the gastrointestinal tract, absorbing or scattering X-rays to provide contrast in radiographic imaging.
Intravenous: 1-2 mL/kg (300 mg I/mL) for contrast-enhanced CT; intra-arterial: 5-80 mL per injection depending on procedure; maximum total dose 4 mL/kg.
20-40 mL orally as a single dose; may repeat if necessary.

The terminal elimination half-life of iohexol in patients with normal renal function (creatinine clearance > 90 mL/min) is approximately 1.5 to 2 hours. In patients with renal impairment, the half-life is significantly prolonged (up to 30 hours or more in severe renal failure), necessitating dose adjustment and careful monitoring.
Not applicable (non-absorbed contrast agent).
Omnipaque 300 (iohexol) is primarily eliminated unchanged by the kidneys via glomerular filtration. Renal excretion accounts for >95% of the administered dose within 24 hours in patients with normal renal function. Fecal excretion is negligible (<1%). Billiary excretion is minimal, with less than 0.1% recovered in bile or feces.
Barium sulfate is insoluble and not absorbed; >99% eliminated unchanged in feces via gastrointestinal transit. No renal or biliary elimination.
