Diatrizoic acid

Diatrizoic acid (or its anionic form, Diatrizoate), also known as amidotrizoic acid, or 3,5-Diacetamido-2,4,6-triiodobenzoic acid, is an iodine-containing radiocontrast agent. It is also used to kill tapeworms.

Diatrizoate is considered a high-osmolality contrast agent. Its osmolality ranges from approximately 1500 mOsm/kg (50% solution) to over 2000 mOsm/kg (76% solution).

Administration

 * It is given intravenously (under brand name Hypaque®, GE Healthcare) to enhance contrast in computed tomography, to image the kidneys and related structures, and to image blood vessels.
 * It is given orally or by enema (Gastrografin®, Gastrovist®, Gastrovision®, MD-Gastroview®) to image the gastrointestinal tract.
 * It is given by Foley catheter (Cystografin®) to image the urinary tract

Contraindications
A history of sensitivity to iodine is not a contraindication to using diatrizoate, although it suggests caution in use of the agent.
