Chelating and medical interest Chelating agent: organic chemicals that form coordination bonds with a central metal ion, used to chemically remove ions from solutions, medicinally against microorganisms, to treat metal poisoning and in chemotherapy protocols. Dental agent: biologically active substance intended for use in diagnosis, treatment, or prevention of oral disease or other oral abnormalities. Dental caries inhibitor: any substance or agent which suppresses or prevents the development of dental cavities or caries. Drug/agent: biologically active substance, including those intended for use in diagnosis, treatment, or prevention of disease or other abnormalities, for the relief of suffering, or control or improvement of a physical or mental state; includes biological products. Chelation Therapy: Chelation is a chemical process that has applications in many areas, including medical treatment, environmental site rehabilitation, water purification, and so forth. In the medical environment, Chelation is used to treat cardiovascular disease, heavy metal toxicity, and to remove metals that accumulate in body tissues because of genetic disorders (hemochromatosis). This protocol will address the use of Chelation therapy for the removal of heavy metals as a result of ingested or environmental exposure. Chelation therapy, simply defined, is the process by which a molecule encircles and binds (attaches) to the metal and removes it from tissue. Depending on the drug used, chelating agents specific to the heavy metal involved are given orally, intramuscularly, or intravenously. Once the bound metal leaves the tissue, it enters the bloodstream, is filtered from the blood in the kidneys, and then is eliminated in the urine. The decision to chelate should be made only by professionals with experience using chelation therapy, preferably in consultation with a poison control center or a medical toxicologist.
How does Chelation work to improve health? Chelation Therapy, along with nutrition, promotes health by correcting the major underlying cause of arterial blockage and heart disease. Damaging oxygen free radicals are increased in the presence of such metals as iron, lead, and aluminum, and are believed to act as a chronic irritant to blood vessel walls and cell membranes. (EDTA) Chelation Therapy and other agents remove the heavy metals, thus decreasing the oxidant burden on the body and increasing its antioxidant reserves. Other risk factors for heart disease including high homocysteine and insulin levels are also addressed. This combined approach utilizing nutrition and Chelation Therapy has helped many people rid themselves of angina pains and prevent further arterial blockages. The following table summarizes chelating agents, the heavy metals they are used to treat, their route of administration, and their brand name. Chelating Agent Toxin Drug Dimercaprol (BAL) Arsenic Lead Mercury (inorganic) Dimercaptol Injection B.P. BAL in Oil Dimercaptosiccinic acid (DMSA) (Succimer) Arsenic Lead Mercury Chemet Dimer capto propane sulfonate (DMPS) Arsenic Bulk form for compounding by pharmacists D-pencil amine Arsenic Mercury Lead Metalcaptase Pencil amine Cuprimine Deepen Ethylene diamin tetra- acetic acid (EDTA) (Edetate disodium) Lead Cheal amide Versenate
Chelation can be accomplished with nutrients that protect our bodies from heavy metals. 1- Magnesium protects us from aluminum 2- Amino acids, calcium, iodine, selenium, vitamin C, and zinc protest us from arsenic. 3- Amino acids, calcium, vitamin C and zinc protect us from cadmium. 4- Amino acids, calcium, iron, Vitamin C, vitamin e, and zinc protect us from lead. 5- Amino acids, pectin selenium, and vitamin C protect us from mercury. 6- Vitamin C, molybdenum and sulfur-containing amino acids(cysteine and tyrosine) chelate copper.
