Diatrizoic acid (or its anionic form, diatrizoate), also known as amidotrizoic acid, or 3,5-diacetamido-2,4,6-triiodobenzoic acid, is a radiocontrast agent containing iodine.
Diatrizoate sodium is a contrast agent used during the X-rays test. It can be used as a diagnostic aid agent during angiography, urography and radiography. It can be applied during visualizing veins, the urinary system, gastrointestinal tract, spleen and joints as well as during the computer tomography (CT scan). It is used in cases where barium is not suitable for application such as patient being allergic to barium. The mechanism of action of Diatrizoate sodium is that it can block the X-rays so that the body structure containing iodine to be delineated in contrast to those structures that free of iodine, further allowing the visualization of those related areas.
