Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Iodinated radiocontrast agent that attenuates X-rays by increasing radiopacity of blood vessels and tissues, allowing visualization during imaging procedures.
Lipiodol is an iodinated ethyl ester of the fatty acids of poppyseed oil. It acts as a radiopaque contrast agent for imaging due to its iodine content, and in chemoembolization, it selectively accumulates in hepatocellular carcinoma (HCC) via tumor neovasculature and is retained due to lack of lymphatic drainage, allowing targeted delivery of chemotherapeutic agents.
Intravenous: 0.5-2 mL/kg of iomeprol 300-400 mg I/mL for imaging, not exceeding 200 mL total dose; arterial: up to 250 mL per procedure.
Lymphangiography: 5-20 mL injected slowly into lymphatic vessels. Uterine/Fallopian tube imaging: 3-20 mL injected through cervix. Hepatic chemoembolization: 5-15 mL mixed with chemotherapeutic agents injected into hepatic artery.

Terminal elimination half-life is approximately 1.5-2 hours in patients with normal renal function. In renal impairment, half-life is prolonged (up to 10-30 hours in severe impairment), necessitating dose adjustment and monitoring. The half-life is not significantly affected by hepatic impairment.
Terminal elimination half-life is approximately 50-60 days, reflecting slow clearance from lipid-rich tissues.
Iomeprol is almost exclusively eliminated via renal glomerular filtration, with 92-98% of the administered dose recovered unchanged in urine within 24 hours. Less than 2% is excreted in feces via biliary elimination. In patients with normal renal function, renal clearance approximates glomerular filtration rate.
Primarily eliminated via biliary/fecal route as unchanged drug; less than 1% excreted renally.
