Abstract:
Scopolia extract (SE) contains hyoscyamine and scopolamine, which are both anticholinergic. It is usually used as a patent medicine to treat gastrointestinal disorders, to relieve spasmotic discomfort, or to decrease the secretion of gastric acid. Poisoning by SE presents similar symptoms and signs as other types of anticholinergic poisoning. We report a case of severe anticholinergic poisoning after accidentally drinking 8 ml of SE. The patient presented with acute delirium and was successfully treated with physostigmine.

Indirect-Acting Cholinergic Agonists: Pharmacological Actions
At the neuromuscular junction, these agents work by inhibiting the breakdown of acetylcholine, allowing it to remain bound to the receptor and bind to nearby receptors. This process leads to repetitive firing of the endplate, causing muscle...
Antidotes
Specific antidotes operate by inhibiting the enzymes that control biochemical pathways, reducing the production of harmful metabolites.
An example of an antidote is atropine, which counteracts the detrimental effects of cholinesterase inhibitors. It achieves this by deactivating muscarinic receptors,...
