IOHEXOL vs MD-76R
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Non-ionic, water-soluble, iodinated contrast agent that increases the radiopacity of vascular structures and body cavities, allowing visualization during radiographic procedures. It does not bind to serum proteins and is rapidly distributed in extracellular fluid.
MD-76R is a radiopaque contrast agent that contains iodine, which attenuates X-rays, thereby enhancing the contrast of blood vessels and tissues during radiographic procedures. It functions by increasing the absorption of X-rays in areas where it is present, allowing for visualization of vascular structures and organ perfusion.
Intravenous: 300-370 mg iodine/kg (0.3-0.37 mL/kg of 300 mg I/mL solution) for contrast imaging; typical range 15-150 mL per procedure depending on examination. Intra-arterial: Doses vary by procedure, typically 1-10 mL total. Do not exceed 3 mL/kg total dose.
2–4 mL/kg intravenously, maximum 150 mL per procedure.

Clinical Note
moderateIohexol + Metformin
"The risk or severity of adverse effects can be increased when Iohexol is combined with Metformin."
Terminal elimination half-life approximately 2-3 hours in patients with normal renal function. In patients with severe renal impairment (CrCl <30 mL/min), half-life may be prolonged up to 30-60 hours, necessitating dose adjustment or avoidance.
Terminal half-life 1-2 hours; prolonged in renal impairment.
Primarily renal via glomerular filtration; 90-100% of administered dose excreted unchanged in urine within 24 hours. Less than 2% excreted in feces. Biliary excretion negligible (<1%).
Primarily renal; 95% eliminated unchanged in urine within 24 hours; <1% fecal.
