Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Iothalamate meglumine is a water-soluble iodinated radiographic contrast agent that attenuates X-rays, providing vascular and organ opacification. It distributes in the extracellular fluid and is excreted unchanged by glomerular filtration.
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: 50-300 mL of a 30% solution (150-900 mg iodine/kg) as a single dose for contrast enhancement. Dosing depends on procedure and patient weight.
20-40 mL orally as a single dose; may repeat if necessary.

Terminal elimination half-life: 1.5-2 hours (normal renal function); prolonged to 20-40 hours in severe renal impairment (CrCl <30 mL/min)
Not applicable (non-absorbed contrast agent).
Renal (90-100% unchanged via glomerular filtration within 24 hours); minimal biliary/fecal (<1%)
Barium sulfate is insoluble and not absorbed; >99% eliminated unchanged in feces via gastrointestinal transit. No renal or biliary elimination.
