Dimercaprol is the antidote of choice in the treatment of acute arsenic (except arsine), mercury, or gold poisoning resulting from ingestion of salts of these metals or following overdosage of therapeutic agents containing these metals. Dimercaprol administration should be accompanied by appropriate supportive measures and is most effective when administered early in the course of the poisoning. In the treatment of acute poisoning by mercury salts, dimercaprol is most effective if administered within 1-2 hours following ingestion, since extensive mercury-induced renal damage cannot be reversed. Dimercaprol is not effective in the treatment of poisonings resulting from monoalkyl mercury compounds, and the drug is only minimally effective in chronic mercury poisoning. Although dimercaprol is usually of no value in the treatment of hypersensitivity reactions to mercury compounds, mercury-induced acrodynia (pink disease) in infants and children responds to treatment with dimercaprol. Dimercaprol is usually effective in the treatment of chronic poisoning from inorganic or organic arsenicals, but may be of little value if aplastic anemia, hemorrhagic encephalitis, or jaundice has developed. In one patient who experienced protein-loss enteropathy in association with arsenic poisoning, hypoproteinemia and edema improved following dimercaprol therapy. The drug is ineffective in the treatment of poisoning resulting from arsine gas (AsH3). Gold-induced dermatitis and gold-induced thrombocytopenia may improve following dimercaprol therapy. /Use included in US product label/

Although dimercaprol chelates lead, other agents (e.g., edetate calcium disodium (calcium EDTA), succimer) generally are preferred for the management of most cases of moderate lead poisoning. However, dimercaprol is useful as an adjunct to edetate calcium disodium and concomitant administration of the drugs is preferred, at least initially, in the management of patients with severe lead poisoning (blood lead concentrations exceeding 70 ug/dL) and/or in those with acute lead encephalopathy (which occurs most often in children). Concomitant administration of dimercaprol and edetate calcium disodium increases the rate of excretion of lead, lowers mortality, and may lower the incidence of brain damage as compared with the use of edetate calcium disodium alone; however, such concomitant therapy does not completely eliminate the risk of permanent severe residual brain damage. Since lead encephalopathy occurs only rarely in adults, experience with the use of the combination in these patients is limited; however, use of dimercaprol and edetate calcium disodium has resulted in prompt relief of symptoms in a few adults with lead encephalopathy. Although concomitant therapy with dimercaprol and edetate calcium disodium also has been recommended in symptomatic patients with blood lead concentrations less than 70 ug/dL, the American Academy of Pediatrics currently states that the toxicity of dimercaprol and the current availability of alternative drugs mandate its use only in the most serious cases of lead poisoning (i.e., blood lead concentrations exceeding 70 ug/dL or when symptoms suggestive of encephalopathy are present). Edetate calcium disodium generally is used alone (i.e., without dimercaprol) in asymptomatic patients with blood lead concentrations of 45-70 ug/dL. ... Dimercaprol is not useful in acute poisonings resulting from alkyl lead compounds (e.g., tetraethyl lead). /Use included in US product label/

Dimercaprol is potentially nephrotoxic. Since the chelate dissociates in acid medium, the urine should be kept alkaline during dimercaprol therapy to protect the kidneys. Dimercaprol should be used with caution and/or the dosage reduced in patients with oliguria. If acute renal failure develops during therapy, the drug should be discontinued or used very cautiously because serum concentrations of dimercaprol may reach toxic levels.
American Society of Health System Pharmacists; AHFS Drug Information 2010. Bethesda, MD. (2010)
Adverse effects of dimercaprol are usually mild and transitory and occur in about one-half of patients who receive an IM dose of 5 mg/kg. If the dose of dimercaprol exceeds 5 mg/kg, most patients will experience vomiting, seizures, and stupor or coma which may begin within 30 minutes after injection and usually subside in 1-6 hours. Prophylactic or therapeutic administration of ephedrine or an antihistamine may prevent or relieve many of the mild adverse effects of dimercaprol. The most frequent adverse effect, a rise in systolic and diastolic blood pressure which is dose related and may be accompanied by tachycardia, may appear 15-30 minutes following the injection and blood pressure usually returns to normal within 2 hours. Frequently pain and occasionally sterile abscesses occur at the injection site, particularly if the drug is not administered deep IM.
American Society of Health System Pharmacists; AHFS Drug Information 2010. Bethesda, MD. (2010)
Other adverse effects that may occur include nausea, vomiting, headache, sweating, and a feeling of constriction (or pain) in the throat, chest, or hands which may be accompanied by anxiety, nervousness or restlessness, and weakness. Muscular aches and pains, muscle spasms, tingling of extremities, and abdominal pain have also been reported.
American Society of Health System Pharmacists; AHFS Drug Information 2010. Bethesda, MD. (2010)
Dimercaprol has a strong odor and imparts an unpleasant mercaptan-like odor to the patient's breath. The drug may also produce a burning sensation of the lips, mouth, throat, eyes, and penis, and pain in the teeth. Blepharal spasm, conjunctivitis, lacrimation, rhinorrhea, and salivation may also occur. When the drug is applied topically, it produces erythema and edema.

For the treatment of arsenic, gold and mercury poisoning. Indicated in acute lead poisoning when used concomitantly with edetate calcium disodium (DB00974).
FDA Label
Due to its oily nature, dimercaprol is not absorbed orally and its administration requires a deep intra-muscular injection that is extremely painful and allergenic. It was found to mobilize and relocate lead to the brain, increasing its neurotoxic effects. Despite that fact that dimercaprol increases cadmium excretion, there is an associated increase in kidney cadmium concentration. Because of this, dimercaprol must be avoided in patients with cadmium toxicity.

Because it is a lipophilic drug, dimercaprol penetrates rapidly the intracellular spaces. The highest concentrations are found in the liver, kidneys, brain and small intestine. Due to its lipophilic characteristic, the complexes formed with mercury and other metals may be redistributed into sensitive cells in the brain following dimercaprol treatment.

Following absorption, dimercaprol is distributed to all tissues (mainly in the intracellular space) including the brain, with highest concentrations in the liver and kidneys.
American Society of Health System Pharmacists; AHFS Drug Information 2010. Bethesda, MD. (2010)
Following IM injection of therapeutic doses of dimercaprol, peak blood concentrations are attained in 30-60 minutes. Dimercaprol is slowly absorbed through the skin following topical application.
American Society of Health System Pharmacists; AHFS Drug Information 2010. Bethesda, MD. (2010)
Dimercaprol is not absorbed orally. It is rapidly absorbed after intramuscular injection and persists for at least 12 hours. Approximately 80% of the dose is absorbed after 1 hours and 90% after 6 hours. Maximal blood concentrations are attained within 1 hour. Hepatic metabolism (by glucuronidation) and excretion are essentially complete within 4 hours. Dimercaprol is the only commonly used chelating agent that readily crosses cellular membranes; as a result, the concentration in certain organs (liver, kidney, small intestine) can be up to five times that in the blood.

The drug has a short half life.
The sulfhydryl groups of dimercaprol form complexes with certain heavy metals thus preventing or reversing the metallic binding of sulfhydryl-containing enzymes. The complex is excreted in the urine.
Dimercaprol is much more effective when given as soon as possible after exposure to the metal because it is more effective in preventing inhibition of sulfhydryl enzymes than in reactivating them. Dimercaprol antagonizes the biological actions of metals that form mercaptides with essential cellular sulfhydryl groups, principally arsenic, gold, and mercury. It also is used in combination with CaNa2EDTA to treat lead poisoning, especially when evidence of lead encephalopathy exists. Intoxication by selenites, which also oxidize sulfhydryl enzymes, is not influenced by dimercaprol
Hardman, J.G., L.E. Limbird, P.B., A.G. Gilman. Goodman and Gilman's The Pharmacological Basis of Therapeutics. 11th ed. New York, NY: McGraw-Hill, 2006., p. 1770
The pharmacological actions of dimercaprol result from formation of chelation complexes between its sulfhydryl groups and metals. The molecular properties of the dimercaprol-metal chelate have considerable practical significance. With metals such as mercury, gold, and arsenic, the strategy is to attain a stable complex to promote elimination of the met al. Dissociation of the complex and oxidation of dimercaprol can occur in vivo. Furthermore, the sulfur-metal bond may be labile in the acidic tubular urine, which may increase delivery of metal to renal tissue and increase toxicity. The dosage regimen therefore is designed to maintain a concentration of dimercaprol in plasma adequate to favor the continuous formation of the more stable 2:1 (BAL-metal) complex and its rapid excretion. However, because of pronounced and dose-related side effects, excessive plasma concentrations must be avoided. The concentration in plasma therefore must be maintained by repeated fractional dosage until the offending metal can be excreted.

Ca2+ is involved in the regulation of a variety of physiological processes, but a persistent increase in free cytosolic Ca2+ concentrations may contribute to cell injury. Dimercaprol (BAL) is a compound used in the treatment of mercury intoxication, but presents low therapeutic efficacy. The molecular mechanism responsible for the BAL toxicity is poorly known. In the present study, the effect of BAL and inorganic and organic mercury on Ca2+ transport by Ca2+-ATPases located in the sarco/endoplasmic reticulum of fast-skeletal muscle and brain was examined. Ca2+ uptake by brain and fast-skeletal muscle microsomes was inhibited in a dose-dependent manner by Hg2+. The calculated IC50 for Ca2+ uptake inhibition by HgCl2 was 1.05+/-0.09 microM (n = 8) for brain and 0.72+/-0.06 microM (n = 9) for muscle. The difference was significant at p < 0.01 (data expressed as mean +/- SD). At a low concentration (1 microM), 2,3-dimer-captopropanol had no effect on Ca2+ uptake by brain or muscle vesicles and did not abolish the inhibition caused by Hg2+. A high concentration of BAL (1 mM) nearly abolished the inhibition caused by 1.75 microM HgCl2 or 6 microM CH3HgCl in skeletal muscle. Surprisingly, at intermediate concentrations (40-100 microM) BAL partially inhibited Ca2+ transport in brain but had no effect on muscle. Furthermore, ATP hydrolysis by brain or muscle microsomes was not inhibited by BAL. These results suggest that in brain microsomes BAL affects in a different way Ca2+ transport and ATP hydrolysis. The increase in BAL concentration observed after toxic administration of this compound to experimental animals may contribute to deregulate Ca2+ homoeostasis and, consequently, to the neurotoxicity of BAL.
