Dimercaprol (INN) or British anti-Lewisite (abbreviated BAL), is a compound developed by British biochemists at Oxford University during World War II. In Pharmacology, bioavailability is used to describe the fraction of an administered Dose of unchanged drug that reaches the Systemic circulation, one of Drug metabolism is the Metabolism of drugs, their Biochemical modification or degradation usually through specialized enzymatic systems The biological half-life of a substance is the time it takes for a substance (drug radioactive nuclide or other to lose half of its pharmacologic physiologic or radiologic activity Excretion is the process of eliminating waste products of Metabolism and other non-useful materials The pregnancy category of a pharmaceutical agent is an assessment of the risk of fetal injury due to the pharmaceutical if it is used as directed by the mother during The regulation of therapeutic goods, that is drugs and therapeutic devices, varies by jurisdiction In Pharmacology and Toxicology, a route An International Nonproprietary Name ( INN; also known as rINN, for recommended International Nonproprietary Name or pINN for proposed The University of Oxford (informally "Oxford University" or simply "Oxford" located in the city of Oxford, Oxfordshire, England is the World War II, or the Second World War, (often abbreviated WWII) was a global military conflict which involved a majority of the world's nations, including It was developed secretly as an antidote for Lewisite, the now-obsolete arsenic-based chemical warfare agent. Lewisite is a Chemical compound from a chemical family called Arsines While it is colorless and odorless when pure Lewisite is usually found as an oily yellow or Arsenic (ˈɑrsənɪk is a Chemical element that has the symbol As and Atomic number of 33 Chemical warfare involves using the toxic properties of Chemical substances to kill injure or incapacitate an enemy. Today, it is used medically in treatment of arsenic, mercury and lead, and other toxic metal poisoning. Arsenic (ˈɑrsənɪk is a Chemical element that has the symbol As and Atomic number of 33 Mercury (ˈmɜrkjʊri also called quicksilver or hydrargyrum, is a Chemical element with the symbol Hg ( Latinized hydrargyrum Characteristics Lead has a dull luster and is a dense, Ductile, very soft highly Toxic metals are Metals that form Poisonous soluble compounds and have no biological role i In addition, it has in the past been used for the treatment of Wilson's disease, a genetic disorder in which the body tends to retain copper. Wilson's disease or hepatolenticular degeneration is an Autosomal recessive Genetic disorder in which Copper accumulates in tissues Copper (ˈkɒpɚ is a Chemical element with the symbol Cu (cuprum and Atomic number 29 
Heavy metals act by chemically reacting with adjacent sulfhydryl residues on metabolic enzymes, creating a chelate complex that inhibits the affected enzyme's activity. In Organic chemistry, a thiol is a compound that contains the functional group composed of a Sulfur atom and a Hydrogen atom (-SH Chelation is the binding or complexation of a bi- or multidentate Ligand. Dimercaprol competes with the sulfhydryl groups for binding the metal ion, which is then excreted in the urine.
Dimercaprol is itself toxic, with a narrow therapeutic range and a tendency to concentrate arsenic in some organs. The therapeutic index (also known as therapeutic ratio) is a comparison of the amount of a therapeutic agent that causes the therapeutic effect to the amount that causes toxic Other drawbacks include the need to administer it by painful intramuscular injection. Intramuscular injection is the injection of a substance directly into a Muscle.
BAL has been found to form stable chelates in vivo with many toxic metals including inorganic mercury, antimony, bismuth, cadmium, chromium, cobalt, gold, and nickel. Mercury (ˈmɜrkjʊri also called quicksilver or hydrargyrum, is a Chemical element with the symbol Hg ( Latinized hydrargyrum Antimony (IPA (Received Pronunciation, /ˈæntɪmoʊni/ (US is a Chemical element with the symbol Sb (stibium meaning "mark" and Bismuth (ˈbɪzməθ is a Chemical element that has the symbol Bi and Atomic number 83 Cadmium (ˈkædmiəm is a Chemical element with the symbol Cd and Atomic number 48 Chromium (ˈkroʊmiəm is a Chemical element which has the symbol Cr and Atomic number 24 Cobalt (ˈkoʊbɒlt is a hard lustrous silver-grey Metal, a Chemical element with symbol Co. Gold (ˈɡoʊld is a Chemical element with the symbol Au (from its Latin name aurum) and Atomic number 79 Nickel (ˈnɪkəl is a metallic Chemical element with the symbol Ni and Atomic number 28 However, it is not necessarily the treatment of choice for toxicity to these metals. BAL has been used as an adjunct in the treatment of the acute encephalopathy of lead toxicity. It is a potentially toxic drug, and its use may be accompanied by multiple side effects. Although treatment with BAL will increase the excretion of cadmium, there is a concomitant increase in renal cadmium concentration, so that its use in case of cadmium toxicity is to be avoided. It does, however, remove inorganic mercury from the kidneys; but is not useful in the treatment of alkylmercury or phenyl mercury toxicity. BAL also enhances the toxicity of selenium and tellurium, so it is not to be used to remove these metals from the body. Selenium (səˈliniəm is a Chemical element with the Atomic number 34 represented by the chemical symbol Se, an atomic mass of 78 Tellurium (tɪˈlʊəriəm/ /tɛl- is a Chemical element that has the symbol Te and Atomic number 52
