What is the function of Protopam chloride in poisoning cases?

To counteract cyanide poisoning
Reactivates cholinesterase in cases of carbamate poisoning
Helps reactivate cholinesterase in organophosphate poisoning, but not effective with carbamates
Neutralizes acid ingestion

The correct answer is: Helps reactivate cholinesterase in organophosphate poisoning, but not effective with carbamates

Protopam chloride is a medication that is used as an antidote for organophosphate poisoning. Organophosphates are a type of insecticides that inhibit the enzyme cholinesterase, causing paralysis and eventually death. Protopam chloride helps to reactivate cholinesterase in cases of organophosphate poisoning, making it a suitable treatment option. However, it is not effective in cases of carbamate poisoning, which also involves cholinesterase inhibition. Option A is incorrect because Protopam chloride is not used to counteract cyanide poisoning. Option B is incorrect because it states that it reactivates cholinesterase in carbamate poisoning, which is not true. Option D is incorrect because Protopam chloride does not neutralize acid ingestion.
