Final answer:
The antidote to atropine poisoning is a muscarinic agonist, as atropine blocks muscarinic acetylcholine receptors. Drugs with anti-anxiety effects are mainly anxiolytics like benzodiazepines.
Step-by-step explanation:
The question relates to the reversal of the effects of succinylcholine, which is a muscle relaxant commonly used during the process of intubation. Succinylcholine is not reversed, as it undergoes rapid hydrolysis by plasma cholinesterase, and its effects wear off naturally within minutes.
An antidote to atropine poisoning would be a muscarinic agonist, as atropine is an anticholinergic drug that acts as an antagonist to muscarinic acetylcholine receptors. Therefore, the correct answer to that question is a muscarinic agonist.
Drugs with anti-anxiety effects are typically anxiolytic in nature. Substances such as benzodiazepines or selective serotonin reuptake inhibitors (SSRIs) are often prescribed for their anti-anxiety properties.
