LIPIODOL vs RENOVUE-65
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Iothalamate meglumine is an ionic, high-osmolality iodinated contrast agent that attenuates X-rays, enhancing vascular and tissue contrast. It acts by increasing the radiopacity of blood vessels and organs during imaging.
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.
Intravenous injection, 10 mL (6.48 g iobitridol) as a single dose. Repeat dosing: up to 3 additional doses within 30 minutes, maximum 40 mL per procedure.

Terminal elimination half-life is approximately 50-60 days, reflecting slow clearance from lipid-rich tissues.
Terminal elimination half-life: 2.0 hours in patients with normal renal function; prolonged to >24 hours in severe renal impairment (CrCl <10 mL/min).
Primarily eliminated via biliary/fecal route as unchanged drug; less than 1% excreted renally.
Renal: 100% as unchanged drug; no biliary or fecal elimination.
