Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Iodinated nonionic radiocontrast agent that attenuates X-rays and enhances vascular and tissue contrast.
20-40 mL orally as a single dose; may repeat if necessary.
Intravascular administration: Adult dose is 50-150 mL (16-48 g iodine) intravenously as a bolus or infusion, depending on the procedure. For CT imaging, typical dose is 75-150 mL at 1-3 mL/sec.

Not applicable (non-absorbed contrast agent).
Terminal elimination half-life is approximately 2 hours in patients with normal renal function. Clinically, clearance is prolonged in renal impairment, requiring dose adjustment.
Barium sulfate is insoluble and not absorbed; >99% eliminated unchanged in feces via gastrointestinal transit. No renal or biliary elimination.
Primarily renal via glomerular filtration; approximately 95% of the dose excreted unchanged in urine within 24 hours. Biliary/fecal excretion is minimal (<1%).
