MD-60 vs ORAGRAFIN CALCIUM
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 Calcium is a diagnostic radiocontrast agent that contains calcium ipodate. It acts by absorbing X-rays due to its high iodine content (61% iodine by weight). After oral administration, it is absorbed and excreted into the bile, allowing radiographic visualization of the gallbladder and biliary ducts. It may also enhance CT imaging of the liver and biliary tree.
Intravenous administration, 60 mg/kg as a single dose over 30 min.
Oral: 5 mL (1 packet) orally, may repeat in 30-60 minutes if needed. Maximum 2 doses per procedure. Rectal: 100-200 mL of a 1:1 dilution with water as a retention enema.

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 1.2 hours (0.7–2.0 hours) in patients with normal renal function. May be prolonged in renal impairment (up to 18 hours in severe impairment).
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: 90% of absorbed dose excreted unchanged in urine within 24 hours; <10% via feces. Biliary excretion is negligible in the absence of hepatobiliary obstruction.
