LIPIODOL vs MD-50
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.
Iodinated radiographic contrast agent that attenuates X-rays due to its high iodine content, allowing visualization of vascular structures and organs during imaging. It distributes into the extracellular fluid compartment and is excreted unchanged by glomerular filtration.
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.
300 mg intravenously every 12 hours.

Terminal elimination half-life is approximately 50-60 days, reflecting slow clearance from lipid-rich tissues.
Terminal elimination half-life is 2.5-3.0 hours (normal renal function). In patients with renal impairment (CrCl <30 mL/min), half-life may be prolonged up to 24-36 hours, necessitating dose adjustment. For contrast media, the half-life determines the window for imaging procedures.
Primarily eliminated via biliary/fecal route as unchanged drug; less than 1% excreted renally.
Primarily renal excretion of unchanged drug (90-95%) via glomerular filtration; minimal biliary/fecal elimination (<5%).
