Which of the following chelating agent is not used in lead poisoning
**Core Concept**
The treatment of lead poisoning involves the use of chelating agents to bind to the heavy metal and facilitate its excretion. Several agents are used, each with its specific mechanism and indications.
**Why the Correct Answer is Right**
The chelating agents used in lead poisoning include succimer (DMSA), penicillamine, and succimer is actually used in children. However, the chelating agent not used in lead poisoning is deferoxamine, which is typically used to treat iron overload in conditions such as thalassemia major.
* Deferoxamine works by binding to iron, forming a stable complex that can be excreted. It is not effective in treating lead poisoning and may even displace lead from its binding sites.
