Storage Conditions · 3 件

Chelating agents, by their very nature, tend to be corrosive to metals such as copper, zinc, and iron. The alkaline salts corrode aluminum severely, and contact with these salts should be avoided. Stainless steel and most polymers or coatings that are able to withstand dilute alkali are acceptable as construction materials. Solid chelating agents should be stored in a cool, dry place to avoid caking. /Chelating agents/

Total myocardial calcium content of rats treated with adriamycin was very high. Treatment with EDTA decreased calcium levels almost to normal values; however the histological adriamycin-induced cardiac alterations were not prevented.

The effect of EDTA (ethylenediaminetetraacetate) on the antimicrobial activity of 10% sodium sulfacetamide solutions was evaluated in this study by kill rate and minimum /inhibitory/ concentration (mic). EDTA improves the kill rate, but not the mic, for the pseudomonas, serratia, and candida species regardless of the preservative.

... Increased absorption of drugs ... occurs in presence of ... ethylenediaminetetraacetic acid (EDTA). When given orally ... (100-500 mg/kg in rats), the chelator increased ... /the/ rate of absorption of heparin, sulfopolyglucin, mannitol, inulin, decamethonium, sulfanilic acid ... Phenol red, all lipid-insoluble substances which ordinarily are poorly absorbed from GI tract. The wide variety of the chemical structures of these suggests that the chelating agent is acting in a nonspecific way and is not affecting the physical or chemical state of the compounds within the intestine ... /there is/ direct evidence that EDTA acts by increasing the permeability of the intestinal epithelium ... Perhaps EDTA alters permeability by increasing the size of the membrane pores or by widening the spaces between the epithelial cells through the removal of calcium ions.

The effects of EDTA on contractile responses of hamster cremaster arterioles and rat aortic strips to epinephrine (EPI) or norepinephrine (NOR) were examined. Comparable contractile responses were elicited by lower EPI or NOR concentration in presence than in absence of EDTA. Individual responses were maintained in the presence of EDTA but rapidly declined if EDTA was not present. Apparently, oxidation of EPI and NOR reduces apparent vascular reactivity and EDTA prevents or delays the reduction.

/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.

Environmental Fate · 3 件

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 313(SRC), determined from a structure estimation method(2), indicates that ethylenediamine tetraacetic acid is expected to have moderate mobility in soil(SRC). The pKa of ethylenediamine tetraacetic acid is 0.26(3), indicating that this compound will exist almost entirely in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Volatilization of ethylenediamine tetraacetic acid from moist soil surfaces is not expected to be an important fate process(SRC) given its pKa(3). Ethylenediamine tetraacetic acid is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 1.5X10-12 mm Hg at 25 °C(4). A 0% of theoretical BOD using activated sludge in the Japanese MITI test(5) suggests that biodegradation is not important in soil(SRC).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 313(SRC), determined from a structure estimation method(2), indicates that ethylenediamine tetraacetic acid is expected to adsorb to suspended solids and sediment(SRC). A pKa of 0.26(3) indicates ethylenediamine tetraacetic acid will exist almost entirely in the anion form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(SRC). According to a classification scheme(4), an estimated BCF of 3(SRC), from an estimated log Kow of -3.86(5) and a regression-derived equation(6), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Ethylenediamine tetraacetic acid was poorly biodegraded anaerobically(7). Photodegradation half-lives of ethylenediamine tetraacetic acid in lake water at pH 3.1 and 6.5 are reported as 31.1 and 56.8 minutes, respectively(8). Ethylenediamine tetraacetic acid is not expected to undergo hydrolysis in the environment due to lack of functional groups that hydrolyze under environmental conditions(9).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), ethylenediamine tetraacetic acid, which has a vapor pressure of 1.5X10-12 mm Hg at 25 °C(2), is expected to exist solely in the particulate phase in the ambient atmosphere. Particulate-phase ethylenediamine tetraacetic acid may be removed from the air by wet or dry deposition(SRC).

Adverse Effects · 2 件

Dermatotoxin - Skin burns.

There are multiple adverse effects related to the use of EDTA. These side effects are dependent on various factors, including dosage, renal function, and frequency of administration. The most commonly recognized adverse effect is renal toxicity. The toxic effects can manifest as acute tubular necrosis, renal failure, anuria, and proteinuria. Both intramuscular and intravenous routes of administration were shown to increase blood urea nitrogen in more than 25% of patients.;Additionally, calcium EDTA has a strong affinity for zinc, which can lead to a zinc deficiency. The amount of zinc lost from the body was shown to be negatively correlated with weight. A study assessing the efficacy of calcium disodium edetate found that smaller children were losing a larger proportion of zinc than larger children. The study further reinforced the need to monitor levels of zinc during chelation therapy.;Other side effects include fever, nausea, vomiting, chills, fatigue, arthralgia, hypotension, arrhythmias, acute tubular necrosis, proteinuria, tremors, headache, cheilosis, bone marrow depression, anemia, and hypercalcemia. Pain at the injection site is a common adverse drug reaction of intramuscular administration.;Administration of edetate calcium disodium must be carefully distinguished from the administration of edetate disodium. Edetate disodium is similar in structure to edetate calcium disodium; however, it is not complexed with calcium. This minor difference protects serum levels of calcium and avoids life-threatening hypocalcemia. Cases have been reported where patients who were incorrectly given edetate disodium had seizures and cardiac arrest.

Exposure Routes · 2 件

Safe in the present practices of use and concentration. Ingredient, concentration, and use information are available in documents discoverable at https://cir-reports.cir-safety.org

Currently, no antidotes are available for EDTA. In patients who have cerebral edema, increases in intracranial pressure should be treated immediately with osmotic agents. Patients with nephrotoxicity should be given fluids to ensure hydration and be monitored for urine output. Renal function should be continuously monitored even after the development of toxicity. Overall, patients who develop signs or symptoms of toxicity should immediately be discontinued from the drug.

The pharmacologic effects of edetate calcium disodium are due to the formation of chelates with divalent and trivalent metals. A stable chelate will form with any metal that has the ability to displace calcium from the molecule, a feature shared by lead, zinc, cadmium, manganese, iron and mercury. The amounts of manganese and iron metabolized are not significant. Copper is not mobilized and mercury is unavailable for chelation because it is too tightly bound to body ligands or it is stored in inaccessible body compartments. The excretion of calcium by the body is not increased following intravenous administration of edetate calcium disodium, but the excretion of zinc is considerably increased.

Pharmacodynamics · 1 件

Edetate calcium is a heavy metal chelating agent. The calcium in edetate calcium can be displaced by divalent or trivalent metals to form a stable water soluble complex that can be excreted in the urine. In theory, 1 g of edetate calcium can theoretically bind 620 mg of lead, but in reality only about 5 mg per gram is actually excreted into the urine in lead poisoned patients. In addition to chelating lead, edetate calcium also chelates and eliminates zinc from the body. Edetate calcium also binds cadmium, copper, iron and manganese, but to a much lesser extent than either lead or zinc. Edetate calcium is relatively ineffective for use in treating mercury, gold or arsenic poisoning.

Mechanism of Action · 4 件

The pharmacologic effects of edetate calcium disodium are due to the formation of chelates with divalent and trivalent metals. A stable chelate will form with any metal that has the ability to displace calcium from the molecule, a feature shared by lead, zinc, cadmium, manganese, iron and mercury. The amounts of manganese and iron metabolized are not significant. Copper is not mobilized and mercury is unavailable for chelation because it is too tightly bound to body ligands or it is stored in inaccessible body compartments. The excretion of calcium by the body is not increased following intravenous administration of edetate calcium disodium, but the excretion of zinc is considerably increased.

Effects on rat liver glucocorticoid receptor in vitro was studied. At 4 °C, 10 mmole EDTA had a stablizing effect on unbound hepatic glucocorticoid receptors. Apparently, endogenous metal ions are involved in the processes of glucocorticoid-receptor complex stabilization and transformation.

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.

Biological Half-Life · 3 件

The half life of edetate calcium disodium is 20 to 60 minutes.

... About 50% of EDTA admin iv is excreted within 1 hr and 90% within 7 hr. ...

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

Salts of NTA, N-(carboxymethyl) glycine, and of glycine ... Glycolic acid salts are formed from the reaction of sodium cyanide and formaldehyde.

Very small amounts of the impurity, nitrilotriacetate, can be found in EDTA. Nitrilotriacetate is a potential oral carcinogen in rats in large doses. This is not a concern for human exposure given the low concentrations of use of EDTA and the poor dermal absorption of EDTA. Also, although nitrilotriacetate is readily absorbed from the GI tract of the rat, it is poorly absorbed in man.

Disodium EDTA is not expected to contain pesticides, 1,4-dioxane, free ethylene oxide, monochloroacetic acid, sulfite, organic solvents, nitrosamines, or other substances. The maximum concentration of heavy metals and formaldehyde is 10 ppm and 100 ppm, respectively.
