Oxilan® is a radiographic contrast agent used in diagnostic imaging studies. The degree of contrast enhancement is directly related to the iodine content in the administered dose. Dependent on the iodine content, the osmolalities are 2.1 or 2.4 times that of plasma (285 mOsm/kg water).

Reno-30® is a radiopaque contrast agent indicated for retrograde or ascending pyelography. Retrograde pyelography does not include systemic administration of contrast media, so the risk of adverse reactions is extremely rare.

Reno-60® is radiopaque contrast agent with a wide range of indications. Reno-60 should be at body temperature when injected and may need to be warmed before use. Following intravascular injection, iodinated contrast materials are transported through the bloodstream to the kidneys and excreted by glomerular filtration.

Thorotrast is an obsolete contrast medium containing a colloidal suspension of thorium dioxide. Contrast agents based on thorium have been abandoned since they turned out to be carcinogenic.
