Radiation Treatment Medications

The Oak Ridge Institute for Science and Education (ORISE) maintains a repository of clinical information and data on calcium and zinc diethylenetriaminepentaacetate (DTPA) and ferric hexacyanoferrate, also known as Prussian Blue.

Calcium-DTPA and zinc-DTPA are injectable chelating agents used to enhance the excretion of plutonium and other transuranics from the body. Prussian Blue binds to radioactive cesium and thallium in the stomach, thereby enhancing their excretion from the body.


Package inserts are available for radiation treatment pharmaceuticals calcium-DTPA, zinc-DTPA and Radiogardase (Prussian Blue).

Read more about DTPA and Prussian Blue on the Centers for Disease Control and Prevention website.
