ChEBI Name dimercaprol: ChEBI ID CHEBI:64198: Definition A dithiol that is propane-1,2-dithiol in which one of the methyl hydrogens is replaced by a hydroxy group. Mechanism of action. Lewisite causes physical damage to capillaries, which then become leaky, meaning that there is not enough blood volume to maintain blood pressure, a condition called hypovolemia. When the blood pressure is low, the kidneys may not receive enough oxygen and can be damaged. It is given by injection into a muscle. Corneal vascularization is not visible until 5 days after the injury, becoming intense at 14 days. Surprisingly, the mechanisms of action at the molecular level, as well as the coordination features of this traditional drug toward various arsenicals, are still poorly revealed. It is contraindicated in those with peanut allergies. BAL binds to the arsenic in lewisite and Biochem J, 40(4):548-554, 01 Jul 1946 Cited by: 5 articles | PMID: 20273640 | PMCID: PMC1258395.
