Ipodate Sodium

Chemical structure of Ipodate Sodium

Ipodate sodium is a radiocontrast agent that was historically used in medical imaging, particularly for cholecystography and cholangiography. It is an iodinated compound that enhances the contrast of images by increasing the density of the target tissues, allowing for better visualization during diagnostic procedures.

Chemical Properties

Ipodate sodium is a sodium salt of the organic iodine compound, ipodate. It is characterized by its high iodine content, which is responsible for its radiopaque properties. The chemical structure of ipodate sodium includes an aromatic ring with iodine atoms, which contribute to its effectiveness as a contrast agent.

Mechanism of Action

Ipodate sodium works by absorbing X-rays due to its iodine content. When administered, it is selectively taken up by the liver and excreted into the bile. This property makes it particularly useful for imaging the biliary tract and gallbladder. The increased contrast allows for the detection of abnormalities such as gallstones, tumors, or blockages.

Clinical Use

Historically, ipodate sodium was used in oral cholecystography, a procedure to visualize the gallbladder. Patients would ingest the compound, which would then be absorbed and concentrated in the gallbladder. X-ray imaging would follow, providing detailed images of the gallbladder structure and function.

Safety and Side Effects

While effective, ipodate sodium has been largely replaced by newer imaging techniques such as ultrasound and magnetic resonance imaging (MRI), which do not require contrast agents. The use of ipodate sodium can be associated with side effects, including allergic reactions and iodine-induced thyroid dysfunction.

Current Status

Ipodate sodium is no longer commonly used in clinical practice due to advancements in imaging technology. However, it remains a compound of interest in certain research settings and historical studies of radiology.
