Pralidoxime, another antidote, can be considered to reactivate inhibited acetylcholinesterase enzymes, although this is often less important for carbamate poisoning than it is for organophosphate poisoning. [1] The most common cause of death following carbamate poisoning is respiratory failure. [3]
Organophosphate poisoning is poisoning due to organophosphates (OPs). [4] Organophosphates are used as insecticides , medications, and nerve agents . [ 4 ] Symptoms include increased saliva and tear production, diarrhea , vomiting, small pupils , sweating, muscle tremors, and confusion. [ 2 ]
Carbofuran is a carbamate insecticide, banned in the US, the EU and Canada but still widely used in South America, Australia and Asia. [6] It is a systemic insecticide, which means that the plant absorbs it through the roots, and from there the plant distributes it throughout its organs where insecticidal concentrations are attained.
This process is known as aging. Aged phosphate-acetylcholinesterase conjugate is resistant to antidotes such as pralidoxime. Pralidoxime is often used with atropine (a muscarinic antagonist) to help reduce the parasympathetic effects of organophosphate poisoning. Pralidoxime is only effective in organophosphate toxicity.
The organophosphate pesticides also inhibit this enzyme, although irreversibly, and cause a more severe form of cholinergic poisoning [15] (the similar IRAC MoA 1b). [14] Fenoxycarb has a carbamate group but acts as a juvenile hormone mimic, rather than inactivating acetylcholinesterase. [16] The insect repellent icaridin is a substituted ...

In August, the US Food and Drug Administration greenlit a new maker of an old drug used for the most severe cases of lead poisoning, ending a shortage and stopping the need for importation of the ...
Physostigmine is the antidote of choice for Datura stramonium poisoning. It is also an antidote for Atropa belladonna poisoning, the same as for atropine. [3] It has also been used as an antidote for poisoning with GHB, [4] but is poorly effective and often causes additional toxicity, so is not a recommended treatment. [5]
