Sodium acetrizoate (rINN, trade names Urokon, Triurol and Salpix), the sodium salt of acetrizoic acid, is a high-osmolality, water-soluble, iodine-based radiographic contrast medium no longer in clinical use.[1]

Acetrizoate was developed by V.H. Wallingford of Mallinckrodt, and introduced in 1950;[2] it was employed as a contrast agent for several radiographic studies, including pyelography,[3][4] angiography of the brain, carotid arteries and the aorta,[5][6] and cholecystography.[7][8] It was soon found to be highly toxic to the kidneys and nervous system—work urging caution in its administration was published as early as 1959,[9] after reports of adverse reactions ranging from hypersensitivity to brain damage—and was eventually replaced by other agents with higher efficacy and lower toxicity, such as sodium diatrizoate, a closely related compound.[2]
