CHOLOGRAFIN MEGLUMINE vs VASCORAY
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.
VASCORAY is a fixed combination of iodixanol and calcium sodium edetate. Iodixanol is a nonionic, dimeric, isotonic iodinated contrast medium that increases radiographic contrast by attenuating X-rays. Calcium sodium edetate chelates calcium, potentially reducing contrast-induced nephropathy risk.
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.
0.5-1.0 mL/kg intravenously as a single dose, not to exceed 5 mL/kg total.

Terminal elimination half-life is approximately 1-2 hours in patients with normal hepatic function, reflecting rapid biliary excretion; prolonged in hepatic impairment.
Terminal elimination half-life of 8-12 hours in patients with normal renal function; prolonged in renal impairment.
Primarily hepatic excretion via bile into feces; renal excretion accounts for <1% of the dose in patients with normal hepatic function.
Primarily renal (90% unchanged), with 10% biliary/fecal.
