MD-60 vs ORAGRAFIN SODIUM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
MD-60 is a nonionic iodinated contrast agent. It attenuates X-rays by increasing the density of structures and organs, improving radiographic visualization.
Oragrafin Sodium is an oral cholecystographic contrast agent containing sodium ipodate. It is absorbed orally, excreted by the liver into bile, and concentrates in the gallbladder, allowing radiographic visualization. The iodine atoms in the molecule absorb X-rays, providing contrast. It also inhibits thyroid hormone synthesis by blocking iodine organification and may be used in amiodarone-induced thyrotoxicosis.
Intravenous administration, 60 mg/kg as a single dose over 30 min.
Oral: 50-60 mL of a 10% solution (5-6 g sodium iopodate) as a single dose 10-12 hours before cholecystography. Repeat if needed: 50 mL (5 g) the next evening. Intravenous: Not applicable (oral agent).

Terminal elimination half-life is 18–24 hours in patients with normal renal function (CrCl >90 mL/min); prolonged to >40 hours in moderate renal impairment (CrCl 30–60 mL/min), requiring dose adjustment.
Terminal elimination half-life is approximately 60-90 minutes in patients with normal renal function (creatinine clearance > 90 mL/min), reflecting rapid renal clearance of this water-soluble contrast agent.
Primarily renal elimination of unchanged drug (~60% within 24 hours) via glomerular filtration; biliary/fecal excretion accounts for ~30% as metabolites; ~10% undergoes enterohepatic recirculation.
Primarily renal (hepatic/biliary/fecal: minimal). Approximately 80-90% of the absorbed dose is excreted unchanged in urine via glomerular filtration; <10% eliminated in feces via biliary excretion.
