This part describes the specific medical use for which Ca-DTPA is approved.
Ca-DTPA is indicated as a radiomitigation agent for the treatment of individuals with known or suspected internal contamination with the transuranium radionuclides plutonium, americium, or curium. Its therapeutic goal is to enhance the elimination rate of these internally deposited radioactive elements from the body, thereby reducing the internal radiation burden and associated long-term health risks, such as the development of malignancy.
