Final answer:
The treatment for toxicity resulting from antimuscarinic and anticholinergic agents involves using an anticholinergic and an oxime as an antidote. Anticholinergics block the effects of excess acetylcholine, while oximes reactivate the poisoned enzyme by counteracting the nerve agent itself.
Step-by-step explanation:
The standard treatment for toxicity resulting from antimuscarinic and anticholinergic agents involves a combination of an anticholinergic to manage the symptoms and an oxime as an antidote.
Anticholinergics, such as atropine, treat the symptoms by blocking the effects of excess acetylcholine, while oximes like pralidoxime chloride reactivate the poisoned enzyme (acetylcholinesterase) by scavenging the phosphoryl group attached to it, counteracting the nerve agent itself.
The antimuscarinic and anticholinergic agents disrupt the nervous system by inhibiting the function of the enzyme acetylcholinesterase, leading to an accumulation of acetylcholine and continuous transmission of nerve impulses.
