AN-DTPA vs MACROTEC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
AN-DTPA (pentetate calcium trisodium) is a chelating agent that binds to and removes heavy metals, such as plutonium, americium, curium, and other transuranic elements, from the body. It forms stable complexes with these metals, which are then excreted via the kidneys.
Not applicable for diagnostic use.
1 gram by intravenous injection or infusion daily for 5 consecutive days, starting immediately after the end of radiotherapy.
5 mCi (185 MBq) intravenously as a single dose for lung perfusion imaging.
