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.

Administration

  • It is given intravenously (under brand name Hypaque®, Nycomed Imaging) to enhance contrast in computed tomography, to image the kidneys and related structures, and to image blood vessels.
  • It is given by orally or by enema (Gastrografin®, Gastrovist®, Gastrovision®, MD-Gastroview®) to image the gastrointestinal tract.

    • Contraindications

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