IOPAMIDOL-370 vs MD-76
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Iopamidol is a nonionic, water-soluble, iodinated radiographic contrast agent that attenuates X-rays, thereby enhancing vascular and tissue contrast during imaging procedures. Its mechanism is physical rather than pharmacological, based on iodine content and osmolality.
MD-76 is a contrast agent that contains iodine, which attenuates X-rays, thereby enhancing the contrast between vascular structures and surrounding tissues. It distributes in the extracellular fluid compartment and is excreted unchanged by glomerular filtration.
1-2 mL/kg (370 mg iodine/mL) IV up to a maximum of 150 mL per procedure for contrast-enhanced CT; for angiography, dose varies by procedure.
IV: 50-100 mL per dose, administered as a bolus or infusion, not to exceed 3 mL/kg total dose.

Terminal elimination half-life is approximately 2 hours (range 1.5-2.5 hours) in patients with normal renal function. Prolonged to 10-70 hours in patients with renal impairment, necessitating dose adjustment or avoidance.
Terminal half-life: 1.5–2 hours; prolonged in renal impairment (up to 20 hours in anuria); clinical context: allows rapid elimination, suitable for diagnostic imaging
Primarily renal; >90% of administered dose excreted unchanged in urine via glomerular filtration within 24-48 hours. Less than 1% excreted in feces or bile.
Renal: >95% unchanged via glomerular filtration; biliary/fecal: <5%
