IOPAMIDOL-250 vs ORAGRAFIN CALCIUM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Iopamidol is a non-ionic, water-soluble, iodinated radiographic contrast agent that attenuates X-rays, thereby enhancing vascular and tissue contrast during imaging procedures. It acts by increasing the radiodensity of blood vessels and organs.
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.
1-2 mL/kg intravenously for contrast imaging, not to exceed 200 mL total; dose and rate vary by procedure and patient weight.
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 half-life 1.5-2 hours in normal renal function; may extend to 5-10 hours in severe renal impairment (CrCl <30 mL/min)
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).
Renal: >90% unchanged via glomerular filtration; biliary/fecal: <2%
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.
