Muscarine toxicity

Muscarine toxicity is a peripheral cholinergic toxidrome primarily caused by the ingestion of toxic mushrooms, particularly from the *Inocybe* and *Clitocybe* genera, or from exposure to muscarinic receptor agonists Clinical manifestations typically appear rapidly, often within thirty minutes to two hours after exposure, and are characterized by excessive exocrine secretions and autonomic hyperstimulation

Pathophysiologically, the alkaloid muscarine acts as an agonist on postganglionic parasympathetic muscarinic acetylcholine receptors, stimulating the autonomic and peripheral nervous systems without significantly crossing the blood-brain barrier Clinical manifestations typically appear rapidly, often within thirty minutes to two hours after exposure, and are characterized by excessive exocrine secretions and autonomic hyperstimulation
