Also, D-penicillamine was discontinued and Ethylene diamine tetra acetic acid (EDTA) (750 mg tds) and British anti-Lewisite
(BAL) (200 mg q 4h) were administrated.
(Chelating agents increase the urinary excretion of mercury  which includes thiol-based agents such as dimercaprol (British anti-Lewisite
(BAL)), penicillamine, unithiol (2,3-dimercaptopropane-1-sulfonate (DMPS)), and succimer (dimercaptosuccinic acid (DMSA)).
Copper chelators can be used in severe poisoning like dimercaprol, D-penicillamine, British Anti-Lewisite
(BAL), Ethylene Diamine Tetra Acetate (EDTA).
The result was dimercaprol--dubbed British anti-Lewisite
(BAL)--a chelating agent that binds strongly with arsenic species.
Dimercaprol (British anti-Lewisite
; BAL) is used for the treatment of arsenic, gold, and acute mercury poisoning (not effective for chronic mercury poisoning).
The first widely used chelating agent was used as an antidote to the arsenic-based poison gas lewisite; it was named BAL, for British anti-lewisite
, and had strong side effects.
(4) In severe cases, chelation with BAL (Dimercaprol or British anti-lewisite
) caused more rapid recovery.
In addition to chelation treatment with British anti-Lewisite
(BAL) (2.5 mg [kg.sup.-1]) and N-acetyl cysteine (NAC), antibiotherapy and granulocyte colony-stimulating factors (GCSF) were administered.
Several drugs are used in the treatment of lead poisoning, including edetate disodium calcium (CaEDTA), dimercaperol (British anti-Lewisite
), D-penicillamine, and meso-2,3-dimercaptosuccinic acid (succimer).
