DTPA is widely used in industry and medicine. As a medical agent, it is approved for its use in medical imaging and for the decorporation of internally deposited radionuclides. It is FDA approved for the treatment of individuals with known or suspected internal contamination with plutonium, americium or curium to increase the rates of elimination. Due to the pharmacokinetic elimination by the kidneys, pentetic acid conjugated with technetium Tc-99m is being used clinically to estimate physiological parameters such as glomerular filtration rat and effective renal plasma flow.
FDA Label
There are reports in vivo of low stability of complexes of DPTA with uranium and neptunium which is being reported to cause deposition of the radionuclides into the tissues. In the case of plutonium, some preclinical studies have shown a very high urine elimination efficacy 1 hour after initial contamination. This efficacy is conserved for approximately 24 hours while the radiocontaminant is circulating. When the radionuclide is inhaled, it has been reported a DPTA-induced reduction of even 98% of the lung deposits. It is important to consider that pentetic acid can bind directly to other trace metals in the body which can cause deficiencies.
Chelating Agents
Chemicals that bind to and remove ions from solutions. Many chelating agents function through the formation of COORDINATION COMPLEXES with METALS. (See all compounds classified as Chelating Agents.)
Iron Chelating Agents
Organic chemicals that form two or more coordination links with an iron ion. Once coordination has occurred, the complex formed is called a chelate. The iron-binding porphyrin group of hemoglobin is an example of a metal chelate found in biological systems. (See all compounds classified as Iron Chelating Agents.)
Antidotes
Agents counteracting or neutralizing the action of POISONS. (See all compounds classified as Antidotes.)
Absorption
DTPA and its trisodium salts present a very poor bioavailability after oral administration. Therefore, the normal administration of DTPA is done by slow intravenous infusion or inhalation with a nebulizer. When inhaled, the absorption is of about 20% of the administered dose.
Route of Elimination
DTPA metal complexes are quickly excreted in the urine.It is predominantly excreted by the kidney and it is not excreted by non-renal routes to any significant extent.
Volume of Distribution
The volume of distribution of DPTA is 17 L.
Clearance
Pentetic acid presents a very rapid blood clearance which explains for the short half-life. The reported clearance rate in patients with normal renal function is 80-120ml/min.
Pentetic acid and its derivatives present a very minimal metabolism in the body.
In preclinical studies, DTPA has been shown to present a very short half-life of 18.5-31.8 min after intravenous administration.
The calcium and zinc trisodium salts of DTPA achieve the therapeutical potential by exchanging calcium and zinc cations with transuranic radionuclides to form higher affinity complexes and then promote their elimination by glomerular filtration into the urine. DTPA as an acid acts in a very similar way by sequestering ions with its eight coordinate bond forming sites.
