Pentetate zinc trisodiumProduct ingredient for Pentetic acid
- Name
- Pentetate zinc trisodium
- Drug Entry
- Pentetic acid
Pentetic acid, also known as diethylenetriaminepentaacetic acid (DTPA), is a synthetic polyamino carboxylic acid with eight coordinate bond forming sites that can sequester metal ions and form highly stable DTPA-metal ion complexes. DTPA, along with its calcium and zinc trisodium salts, are the only FDA approved agents for the treatment of internal contamination by transuranics.1 It is currently considered, in all the dosage forms, as a member of the list of approved inactive ingredients for drug products by the FDA.6 DPTA was developed by the pharmaceutical company CIS US and FDA approved on April 14, 2004.8
