Final answer:
The suffix typically used for inhaled anticholinergic drugs is '-ine', and these drugs act as muscarinic antagonists, like atropine, to block excess acetylcholine effects. For atropine poisoning, a muscarinic agonist is the antidote.
Step-by-step explanation:
The suffix for inhaled anticholinergic drugs is often '-ine', as seen in drugs like atropine. Atropine acts as an antagonist to muscarinic acetylcholine receptors, blocking the effects of excess acetylcholine. By inhibiting the cholinergic effects, these drugs can manage symptoms such as the bronchial secretions caused by nerve agent poisoning. In such scenarios, the administration of atropine is continued until these secretions clear, which indicates the effectiveness of the treatment.
It's important to note that in the context of atropine poisoning, the antidote would be a muscarinic agonist (option c), which would work to counteract the anticholinergic effects of atropine. Conversely, anticholinergic drugs themselves are not suitable as antagonists to atropine poisoning because they produce similar effects to atropine by inhibiting cholinergic functions.
