Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cholografin meglumine is an iodinated contrast agent that opacifies the biliary tract. It is actively taken up by hepatocytes and excreted into the bile, allowing radiographic visualization of the bile ducts and gallbladder.
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: 20 mL (10.3 g) of a 52% solution (meglumine salt) administered by slow IV injection over 3-5 minutes; repeated once after 10-15 minutes if visualization is inadequate, not to exceed 40 mL total.
20-40 mL orally as a single dose; may repeat if necessary.

Terminal elimination half-life is approximately 1-2 hours in patients with normal hepatic function, reflecting rapid biliary excretion; prolonged in hepatic impairment.
Not applicable (non-absorbed contrast agent).
Primarily hepatic excretion via bile into feces; renal excretion accounts for <1% of the dose in patients with normal hepatic function.
Barium sulfate is insoluble and not absorbed; >99% eliminated unchanged in feces via gastrointestinal transit. No renal or biliary elimination.
