/OTHER TOXICITY INFORMATION/ 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.

Disodium edentate behaves as a weak acid, displacing carbon dioxide from carbonates and reacting with metals to form hydrogen. It is incompatible with strong oxidizing agents, strong bases, metal ions, and metal alloys.

/Investigators/ reported that Disodium EDTA (10 mg/mL) increased the intestinal absorption of neutral, basic, and acidic compounds in the male Sprague-Dawley rat. The chelating agent increased the absorption of (14)C-mannitol and (14)C-inulin from <2% to 7%-b 1%, the absorption of (14)C-N-methyldecamethonium from 2%-3% to 11%-15%, and the absorption of sulfanilic acid from 11%-14% to 26%-32%. Plasma concentrations of the drugs were increased as much as five- or sixfold, compared to controls.

Disodium EDTA at a concentration of 1% (w/v; 24 mM) increased the in situ drug absorption of acetazolamide from the small intestine of male Charles River rats when administered with 1% (w/v) reduced glutathione. Intestinal absorption was increased by 1.5 to 2 times; however, absorption from the stomach was not affected by treatment with EDTA and glutathione. The investigators suggested that Disodium EDTA altered the aqueous permeability of the intestinal epithelium by the chelation of magnesium and calcium ions, thereby separating the epithelial cells.

/HUMAN EXPOSURE STUDIES/ /Investigators/ treated 19 patients for acrosclerosis with iv Disodium EDTA given over a 4- to 6-hour period. A majority of the patients received 2.5 to 3.0 g of Disodium EDTA in 500 cc 5% dextrose and water for 15 days. The doses were adjusted for children. Objective improvement occurred in 7/19 patients, 4 were questionably improved and 8/19 did not improve. Improvement was subjectively determined as healing of gangrenous ulcers, increased joint mobility, decreased pain, softer and more pliable sclerodermatous areas, and decreased dysphagia. One patient developed renal irritation characterized by albuminuria and granular casts that cleared up completely when the drug was discontinued. This was the only patient that received the dose of Disodium EDTA over a 2.5-hour period.

/HUMAN EXPOSURE STUDIES/ The irritancy potential of Disodium EDTA using a 4-hour patch test /was investigated/. A mass of 0.2 g of the powder was applied to the skin of the upper outer arm using a 25-mm Plain Hill Top Chamber containing a moistened Webril pad. To avoid the production of "high reactions", the test material was applied progressively from 15 to 30 minutes to 4 hour. The treatment sites were evaluated at 24, 48, and 72 hours after patch removal for signs of irritancy and graded using a 4-point scale. The positive control was 0.2 mL of 20% sodium dodecyl sulfate. None of the 26 volunteers treated with Disodium EDTA had irritation, compared to 21 of the 26 volunteers treated with SDS.

/HUMAN EXPOSURE STUDIES/ Disodium EDTA was administered iv intermittently in 5-day courses over a 15-month period to four patients with severe, noncalcific acrosclerosis. Each patient received 0.5 g/30 lb body weight dissolved in 500 cc of 5% glucose water and infused slowly over an hour. The total dose ranged from 132 to 212 g. Side effects were minimal and did not require discontinuation of therapy. Eight patients with progressive systemic sclerosis (PSS) served as untreated histologic controls. Five patients served as untreated chemical controls and skin from the forearms of 11 individuals without scleroderma were also chemically analyzed. The four patients treated with Disodium EDTA cooperated well and had subjective and objective softening of the skin. At microscopic examination, untreated cases of scleroderma had severe changes. Three of the four patients treated with Disodium EDTA had a return toward normal in their skin. All EDTA cases had definite softening of the skin clinically. Microscopically, this was observed as increased vascularity, return of fixed tissue cells, and the loosening of the collagen bundles in the dermis and the stratum corneum of the epidermis. Normal calcium values from the 11 donors were not statistically significant from the scleroderma average. The magnesium values for the normal donors were 0.19 +/- 0.05 pg/mg dry tissue and for the scleroderma group, 0.17 +/- 0.05 pg/mg dry tissue.

/HUMAN EXPOSURE STUDIES/ /Investigators/ treated 81 subjects (normal or with cardiac arrhythmias) with 2000 consecutive infusions of Disodium EDTA over a 2-year period. The chelating agent was administered as a 3-g dose and infused as a 0.5% solution in saline. The test solution was injected over a 2 1/2- to 3-hour period on alternate days, 3 days per week. After the first 20 injections, treatment was discontinued for 6 to 8 weeks. The procedure was then repeated until 2000 injections had been given. Four patients died after receiving 60, 33, 22, and 8 infusions of Disodium EDTA; at necropsy, no evidence of nephrosis was observed. Hypotension, hypocalcemia, burning at the injection site, thrombophlebitis, and GI symptoms were reported by the remaining subjects. The investigators did not observe systemic reactions, histamine-like reactions, anemia, dermatitis, hyperglycemia (or glycosuria), or bone decalcification.

/LABORATORY ANIMALS: Acute Exposure/ Five male guinea pigs were injected intracutaneously with a volume of 0.1 mL, then 9 volumes of 0.2 mL Disodium EDTA on alternate days. A challenge injection (0.1 mL) was given 2 weeks after the last induction injection, and the treatment sites were evaluated 24 hours later. The guinea pigs had no signs of allergic reactions.

/LABORATORY ANIMALS: Acute Exposure/ /Investigators/ determined the lethal dose of Disodium EDTA when administered as a single iv injection to rats under ether anesthesia. Disodium EDTA always caused death within 1 minute. The calcium equivalent of the lethal dose was 0.45 mg Ca/100 g rat. Chronic infusion of Disodium EDTA at a rate of 0.05 mL every 20 seconds for 2 to 80 minutes resulted in 0.96 to 1.76 mg Ca/100 g of rat calcium "chelated or removed" before death.

/LABORATORY ANIMALS: Acute Exposure/ Seven dogs per group had blood collected from the femoral artery at a rate of 2 mL/kg/min for a total loss of 30 mL/kg. Thirty minutes later, the blood was added to 4.5% isotonic Disodium EDTA, and the blood was returned to the right femoral vein at rates of 4.6 to 10 mL/kg/min, the final EDTA concentrations were 0.09% and 0.18%. The dogs were evaluated for 15 minutes and 24 hours after the termination of retransfusion. None of the dogs of the low-dose group died as a result of treatment. Venous pressure did not "rise unduly" and arterial pressure returned to normal. Five of the seven dogs of the high-dose group did not have increased arterial pressure, but the venous pressure increased such that the dogs died. In the remaining two dogs of this group, the arterial pressure returned to normal after transfusion and the venous pressure increased only for 10 minutes, then decreased.

/LABORATORY ANIMALS: Acute Exposure/ The acute oral LD50 of Disodium EDTA was 3.7 g/kg for both male and female Wistar rats. Signs of toxicity included ataxia, convulsions, and diarrhea. Changes in tissues were not reported during this study.

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.

This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.

Nephrotoxicity (e.g., acute tubular necrosis, proteinuria, and hematuria) may be minimized by adequate hydration, establishment of adequate urine flow, avoidance of excessive doses, and limitation of continuous administration to 5 or fewer days. Laboratory assessment of renal function should be performed daily during treatment for severe intoxication and after the second and fifth days in other cases.

/SRP:/ Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary.

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.

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.

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

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

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.

/Investigators/ reported that rats fed 0.5%, 1.0%, and 5.0% Disodium EDTA for 12 weeks excreted 82.2%, 44.5%, and 45.4%, respectively, of the ingested dose in the urine and feces. The feces contained 99.4%, 98.2%, and 97.5% of the excreted material and the urine contained 0.6%, 1.8%, and 2.5% of the material for the respective doses.

All of the industrially used methods of manufacture of EDTA and its salts involve the addition of formaldehyde and hydrogen cyanide or an alkali metal cyanide to an aqueous solution of EDTA. The salts, or edetates, are then formed by hydrolysis. EDTA can also be formed by heating tetrahydroxyethylethylenediamine with sodium or potassium hydroxide using a cadmium oxide catalyst. Disodium EDTA was prepared by dissolving EDTA into a hot solution that contained two equivalents of sodium hydroxide. The solution was then allowed to crystallize.
