Final answer:
Anticholinergic toxidrome refers to the signs and symptoms associated with poisoning by anticholinergic substances, and it is typically managed with drugs like atropine which act as muscarinic antagonists. Pilocarpine is an antidote to anticholinergic poisoning due to its muscarinic agonist properties. Anticholinergics also have therapeutic uses, such as in motion sickness treatment.

Rapid Review: Anticholinergic Toxidrome
The treatment of symptoms resulting from nerve agent poisoning often involves the use of anticholinergic drugs such as atropine. Atropine works by blocking muscarinic acetylcholine receptors, thereby reducing the effects of excess acetylcholine. Synthetic anticholinergics like biperiden are used in managing central symptoms of poisoning because they can better cross the blood-brain barrier compared to atropine. An endpoint for administering atropine is the clearing of bronchial secretions, indicating its effectiveness in treating anticholinergic symptoms. Furthermore, a combination of an anticholinergic and an oxime is the standard treatment for such poisonings, with the oxime working by displacing phosphate molecules on cholinesterase enzymes. This allows the normal breakdown of acetylcholine .Extracts from plants like belladonna have historically been used for their anticholinergic properties, dilating pupils for cosmetic reasons. However, due to the toxicity of these extracts and the significant risk of anticholinergic poisoning, they are no longer used in this capacity. Pilocarpine, a muscarinic agonist, serves as an antidote to poisoning by anticholinergic agents like atropine or scopolamine. The use of anticholinergic drugs is not limited to poisoning treatment; they are also utilized for other medical conditions, such as motion sickness, where scopolamine is commonly prescribed as a transdermal patch.
