Anticholinergic poisoning is one of the typical toxidromes. Plant tropane alkaloids – atropine, scopolamine and hyoscyamine – are the common causes of this toxidrome when they enter the human body through GI absorption and/or skin contact. Because the toxins mimic to the essential neurotransmitter acetylcholine, they cause antagonist effects on the parasympathetic nerves with specific receptors that control mucous secretion, sweating, and heart rate. The plants that containing tropane alkaloids are Solanaceae, such as Atropa, Datura, and Mandragora, with the distribution to the individual plant and the ratio of toxins different from species to species. Although the clinical presentations may be slightly different, the antidotes of all the intoxications are physostigmine. Decontamination and supportive care may be required.
