Mechanism of Action

  • 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.
  • The sustained presence of dimercaprol promotes continued excretion of the metallic poisons - arsenic, gold and mercury.
  • It is also used in combination with Edetate Calcium Disodium Injection USP to promote the excretion of lead.
