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. Edetic Acid is the acid form of edetate , a chelating agent with anti-hypercalcemic and anticoagulant properties. Edetic acid binds calcium and heavy metal ions, forming soluble stable complexes which are readily excreted by the kidneys. This results in a decrease in serum calcium levels. This agent is also used as an anticoagulant for blood specimens and is applied as a treatment of lead poisoning. [1]
