4.1 Therapeutic Uses

Anticoagulants; Chelating Agents; Food Additives

National Library of Medicine's Medical Subject Headings online file (MeSH, 2009)


Endrate (Edetate Disodium Injection, USP) is indicated in selected patients for the emergency treatment of hypercalcemia and for the control of ventricular arrhythmias associated with digitalis toxicity. /Included in US product label/

US Natl Inst Health; DailyMed. Current Medication Information for Endrate (edetate disodium, anhydrous) injection, solution (May 2006). Available from, as of February 16, 2012: https://dailymed.nlm.nih.gov/dailymed/lookup.cfm?setid=290c3e9c-c0c6-440a-1a9c-46e3e2b07a77


Disodium edentate is also used therapeutically as an anticoagulant as it will chelate calcium and prevent the coagulation of blood in vitro. Concentrations of 0.1% w/v are used in small volumes for hematological testing and 0.3% w/v in transfusions.

Rowe, R.C., Sheskey, P.J., Quinn, M.E.; (Eds.), Handbook of Pharmaceutical Excipients 6th edition Pharmaceutical Press, London, England 2009, p. 243


Disodium EDTA is used occasionally to terminate the effects of injected calcium, to antagonize digitalis toxicity, or to suppress tachyarrhythmias. /Former/

4.2 Drug Warning

/BOXED WARNING/ The use of this drug in any particular patient is recommended only when the severity of the clinical condition justifies the aggressive measures associated with this type of therapy.

US Natl Inst Health; DailyMed. Current Medication Information for Endrate (edetate disodium, anhydrous) injection, solution (May 2006). Available from, as of February 16, 2012: https://dailymed.nlm.nih.gov/dailymed/lookup.cfm?setid=290c3e9c-c0c6-440a-1a9c-46e3e2b07a77


Clinical studies of edetate disodium did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

US Natl Inst Health; DailyMed. Current Medication Information for Endrate (edetate disodium, anhydrous) injection, solution (May 2006). Available from, as of February 16, 2012: https://dailymed.nlm.nih.gov/dailymed/lookup.cfm?setid=290c3e9c-c0c6-440a-1a9c-46e3e2b07a77


Fatal medication errors have occurred that involve confusion between edetate calcium disodium (calcium EDTA) and edetate disodium (no longer commercially available in the US). Children and adults have mistakenly received edetate disodium instead of edetate calcium disodium; at least 5 deaths have occurred as a result of inadvertent administration of edetate disodium. Although both edetate calcium disodium and edetate disodium are heavy metal antagonists, the 2 drugs were originally approved by the US Food and Drug Administration (FDA) for different uses and have different effects; edetate disodium was formerly FDA approved for use in selected patients for the emergency treatment of hypercalcemia or for the control of ventricular arrhythmias associated with cardiac glycoside toxicity. Use of edetate disodium may result in a substantial, and sometimes fatal, decrease in serum calcium concentrations. In June 2008, FDA withdrew its prior approval for edetate disodium because of safety concerns following a review of the risk-benefit profile of the drug. FDA stated that it was not considering additional action regarding edetate calcium disodium at that time; most of the fatalities following administration of an EDTA drug have involved medication errors in which edetate disodium was administered instead of edetate calcium disodium. FDA has not received reports of any fatalities resulting from the administration of edetate calcium disodium that involve a medication error.

American Society of Health-System Pharmacists 2011; Drug Information 2011. Bethesda, MD. 2011


Edetate Disodium Injection is contraindicated in anuric patients. It is not indicated for the treatment of generalized arteriosclerosis associated with advancing age.

Disodium edentate ... /is/ poorly absorbed from the gastrointestinal tract and /is/ associated with few adverse effects when used as an excipient in pharmaceutical preparations.

Rowe, R.C., Sheskey, P.J., Quinn, M.E.; (Eds.), Handbook of Pharmaceutical Excipients 6th edition Pharmaceutical Press, London, England 2009, p. 243


Twenty male Sprague-Dawley rats were divided into four groups of five animals each. Rats in group 1 received ip injections of (14)C Disodium EDTA, group 2 received this compound on depilated skin, rats in group 3 received this compound on depilated and abraded skin (abraded every 2 or 3 cm over treated area), and group 4 was the control group. The specific activity of the (14)C Disodium EDTA was 21.6 mCi/mM and it was dissolved in saline to yield a final solution of 50 pCi/mL. Animals that received ip injections got 0.5 mL of this solution, or 25 pCi of (14)C Disodium EDTA. Animals that had the compound applied to the skin received 25 pCi of (14)C Disodium EDTA in the form of an ointment (modulan, mineral oil, petrolatum, cetyl alcohol 35:21 :25:12) spread over an area of 50 sq cm spread over a sheet of thin polyethylene. This sheet was taped to the trunk of each animal. A collar was fixed around the neck of the rats. All animals were decapitated 24 hours after treatment. The tissue distribution (per 100 mg wet organ weight) of (14)C Disodium EDTA 24 hours after ip administration was as follows: liver 577+/- 13, small intestine 631 +/- 25, large intestine 696 +/- 19, and kidney 1964 +/- 220. Twenty-four hours after application on normal skin the tissue distribution was as follows: liver 6 +/- 4, small intestine 99 +/- 22, large intestine 107 +/- 24, and kidneys 29 +/- 12. Twenty-four hours after application on abraded skin the tissue distribution was as follows: liver 139 +/- 34, small intestine 214 +/- 76, large intestine 309 +/- 115, and kidneys 222 +/- 30.

5.4 Biological Half-Life

After intravenous administration, the chelate formed is excreted in the urine with 50% appearing in 1 hour and over 95% in 24 hours.

US Natl Inst Health; DailyMed. Current Medication Information for Endrate (edetate disodium, anhydrous) injection, solution (May 2006). Available from, as of February 16, 2012: https://dailymed.nlm.nih.gov/dailymed/lookup.cfm?setid=290c3e9c-c0c6-440a-1a9c-46e3e2b07a77


5.5 Mechanism of Action

Edetate disodium injection forms chelates with the cations of calcium and many divalent and trivalent metals. Because of its affinity for calcium, edetate disodium will produce a lowering of the serum calcium level during intravenous infusion. Slow infusion over a protracted period may cause mobilization of extracirculatory calcium stores. Edetate disodium exerts a negative inotropic effect upon the heart.

US Natl Inst Health; DailyMed. Current Medication Information for Endrate (edetate disodium, anhydrous) injection, solution (May 2006).


Edetate disodium likewise forms chelates with other polyvalent metals and produces increases in urinary excretion of magnesium, zinc and other trace elements. It does not form a chelate with potassium but may reduce the serum level and increase urinary loss of potassium.
