... is the calcium disodium salt of ethylene diamine tetraacetic acid. The calcium salt must be used clinically because the sodium salt has greater affinity for calcium and will produce hypocalcemic tetany. However, the calcium salt will bind lead with displacement of calcium from the chelate. It is poorly absorbed...
