Use of  2,3-Dimercaptosuccinic Acid

2,3-Dimercaptosuccinic Acid (DMSA Powder)is used for the treatment of lead poisoning in children with blood level measured above 45 µg/dL.  It cannot cross the blood–brain barrier of humans, limiting its application for extracting heavy metals from parts of the body other than the central nervous system.

  • for provocation of tissue heavy metals in anticipation of a urine test
  • for the treatment of lead poisoning
  • as agents for the mobilization of cadmium, lead and arsenic owing to the ability of these monoesters to cross cell membranes
