Question

Penicillamine is an antidote for

• A. Lead poisoning
• B. Arsenic poisoning
• C. Mercury poisoning
• D. Copper poisoning

Hint:

Penicillamine is often used in cases of copper toxicity, such as in Wilson's disease, and is known for its chelation properties.

Answer 1

The Correct Option is D

To determine the correct answer to the question about the antidote function of Penicillamine, let's review the uses and properties of Penicillamine.

Penicillamine is a chelating agent commonly used in the treatment of metal poisoning, particularly known for its efficacy in binding and detoxifying metals in the human body. We consider the provided options to identify the correct use:

1. Lead poisoning: Treatment for lead poisoning typically involves agents such as EDTA (ethylenediaminetetraacetic acid), Dimercaprol, and Succimer. Penicillamine is not commonly used for lead poisoning.
2. Arsenic poisoning: Arsenic poisoning is usually treated with agents like Dimercaprol or Succimer. Penicillamine is not the primary choice for arsenic detoxification.
3. Mercury poisoning: Mercury poisoning treatment can include Dimercaprol and Succimer as well, but Penicillamine is not typically used for mercury poisoning.
4. Copper poisoning: Penicillamine is widely known as an effective treatment for copper poisoning. It acts by binding to excess copper and facilitating its excretion from the body. Penicillamine is especially used in conditions like Wilson's disease, which involves excess copper accumulation.

Given these points, Penicillamine is specifically used as an antidote for Copper poisoning. Therefore, the correct answer is highlighted and can be concluded with confidence:

The correct answer is: Copper poisoning.
