What class of drugs is Dimercaprol?
What class of drugs is Dimercaprol?
Dimercaprol is a medication used to treat toxic exposure to arsenic, mercury, gold, and lead. It is in the chelating class of drugs.
Is Dimercaprol a chelator?
Introduction. Dimercaprol, or British anti-Lewisite (BAL), is a parenterally administered heavy metal chelating agent that is used to treat arsenic, gold, copper and mercury poisoning.
How do you administer Dimercaprol?
Dosages of Dimercaprol
- Day 1-2: 10-12 mg/kg/day divided every 6 hours deep intramuscularly (IM) for 2 days.
- Day 3: 5-6 mg/kg/day divided every 12 hours deep IM for 1 day.
- Day 4-14: 2.5-3 mg/kg deep IM once daily for 11 days.
- Severe gold dermatitis: 2.5 mg/kg IM every 4 hours for 2 days, then twice daily for 1 week.
Why is Dimercaprol called BAL?
Emergency physicians are familiar with British anti-Lewisite (BAL) because it is a heavy metal-chelating agent that is recommended in some cases of metal poisoning, especially arsenic.
What are the indications for the use of dimercaprol?
Why is Dimercaprol Prescribed? (Indications) This medication is a chelating agent, indicated in the treatment of metal poisoning with metals such as arsenic, gold and mercury. It is an adjunct to Calcium Disodium Edetate in lead poisoning, and also an adjunct to penicillamine to copper poisoning and Wilson Disease.
What is EDTA antidote?
Ethylenediaminetetraacetic acid (EDTA) is a medication used in the management and treatment of heavy metal toxicity. It is in the chelating class of drugs.
Which antidote is used for lead poisoning?
Dimercaprol (BAL in Oil) Dimercaprol (British antilewisite [BAL], or 2,3-dimercapto-1-propanol) was the first chelator used in encephalopathic individuals and is the drug of choice for treatment of lead toxicity.
What is BAL in biochemistry?
The term BAL is a contraction for British Anti-Lewisite, a compound developed by Peters, Stocken, and Thompson1during the recent war as an antidote to the arsenical blister gases. The chemical name for BAL is 2,3-dimercaptopropanol.
What are the contraindications of dimercaprol?
When should Dimercaprol not be taken? (Contraindications) Extensive liver failure; lactation, hypersensitivity, iron and cadmium poisoning.
Why is EDTA given IV?
Chelation therapy is a treatment that involves repeated intravenous (IV) administration of a chemical solution of ethylenediaminetetraacetic acid, or EDTA. It is used to treat acute and chronic lead poisoning by pulling toxins (including heavy metals such as lead, cadmium, and mercury) from the bloodstream.
Why is EDTA used?
A chemical that binds certain metal ions, such as calcium, magnesium, lead, and iron. It is used in medicine to prevent blood samples from clotting and to remove calcium and lead from the body. It is also used to keep bacteria from forming a biofilm (thin layer stuck to a surface). It is a type of chelating agent.
How does EDTA treat lead poisoning?
Lead poisoning and heavy metal toxicity Chelation therapy using EDTA is the medically-accepted treatment for lead poisoning. Injected intravenously and once in the bloodstream, EDTA traps lead and other metals, forming a compound that the body can eliminate in the urine. The process generally takes 1 to 3 hours.
What is the formula of BAL?
Chemical structures of BAL (British Anti-Lewisite, 2,3-dimercapto-1-propanol) with chemical formula C3H8OS2 (left), and its water-soluble derivatives, 2,3-dimercapto-1-propanesulfonic acid (DMPS) with chemical formula C3H8O3S3 (in the middle), and dimercaptosuccinic acid (DMSA), with chemical formula HO2CCH(SH)CH(SH) …
Where is EDTA used?
In manufacturing, EDTA is used to improve stability of some pharmaceutical products, detergents, liquid soaps, shampoos, agricultural chemical sprays, contact lens cleaners and cosmetics. It is also used in certain blood collection tubes used by medical laboratories.
What is EDTA function?
Can I drink EDTA?
EDTA is also an ingredient in some prescription cancer-fighting medicines. Supplement makers claim that over-the-counter forms of EDTA can be taken by mouth to “detox” the body and make your gastrointestinal tract healthier. There is no scientific evidence to support this.
What is antidote for lead poisoning?
There is no antidote for lead. Treatment of lead poisoning consists of removal from the source of exposure. Chelation therapy should be considered for treatment of severe symptoms or markedly elevated blood lead levels.
How does Dimercaprol act in arsenic poisoning?
Mechanism of action. Arsenic and some other heavy metals act by chelating with adjacent thiol residues on metabolic enzymes, creating a chelate complex that inhibits the affected enzyme’s activity. Dimercaprol competes with the thiol groups for binding the metal ion, which is then excreted in the urine.
What are the indications for the use of Dimercaprol?
What is EDTA formula?
C10H16N2O8Ethylenediaminetetraacetic acid / Formula
What is dimercaprol?
Dimercaprol is a chelator and works by binding with heavy metals. Dimercaprol was first made during World War II. It is on the World Health Organization’s List of Essential Medicines. Dimercaprol has long been the mainstay of chelation therapy for lead or arsenic poisoning, and it is an essential drug.
Does dimercaprol interact with iron?
Dimercaprol forms a toxic complex with iron, cadmium, selenium, or uranium. Iron therapy should not be given concurrently with dimercaprol, and it has been suggested that iron therapy be deferred until at least 24 hours after the last dose of dimercaprol.
What are the side effects of dimercaprol for treating cadmium toxicity?
It is a potentially toxic drug, and its use may be accompanied by multiple side effects. Although treatment with dimercaprol 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.
How long does it take for dimercaprol to work?
A healthcare provider will give you this injection. Dimercaprol is most effective when used within 1 or 2 hours after a sudden poisoning. dimercaprol may not be as effective in treating long-term poisoning (slow poisoning that has occurred over a long period of time).
