EDTA stands for ethylenediaminetetraacetic acid. It is used in chelation therapy for patients with lead poisoning, digoxin toxicity and atherosclerosis. It has side effects which can be harmful if not treated.
History
In the 1940s, EDTA was first used to treat patients with heavy metal poisoning. EDTA chelation therapy is approved by the Food and Drug Administration, and about 1 million patients undergo the treatment each year, according to the University of Maryland Medical Center.
Features
EDTA is a chelating agent. It has the ability to bind to metal ions. This reduces the reactivity of the metal ions in the blood. EDTA is an antioxidant as well. It prevents free radicals from damaging blood vessels.
Applications
Chelation therapy is the main application of EDTA. It is also used by dentists in root canal work. EDTA can let physicians monitor kidney function by measuring the amount of EDTA passed in the urine from the time of injection.
Side Effects
Injection site burning is a common symptom associated with EDTA. More serious side effects include reduced blood sugar, reduced calcium levels, very low blood pressure, irregular heart beat, kidney failure and death.
Considerations
A medical health professional should monitor patients during EDTA chelation therapy. Vitamin and mineral levels should be tested before, during and after treatment. Supplements should be taken to replenish lost vitamins and minerals.
