Diatrizoate, also known as amidotrizoate, Gastrografin, is a contrast agent used during X-ray imaging.[1] This includes visualizing veins, the urinary system, spleen, and joints, as well as computer tomography (CT scan).[1] It is given by mouth, injection into a vein, injection into the bladder, through a nasogastric tube, or rectally.[2][3]
Relatively common side effects include vomiting, diarrhea, and skin redness.[4] Other side effects include itchiness, kidney problems, low blood pressure, and allergic reactions.[1] It is not recommended in people who have an iodine allergy.[1] Diatrizoate is an iodinated ionic radiocontrast agent with high osmolality.[2]
Diatrizoate was approved for medical use in the United States in 1954.[4] It is on the World Health Organization's List of Essential Medicines.[5]
