Plant tropane alkaloids atropine and scopolamine are very strong anticholinergic drugs used in medicine and also found their place in military medicine, in particular atropine as an antidote in case of poisonings by nerve gases. Atropine and scopolamine both easily penetrate the blood-brain barrier and may cause central nervous system toxicity.
Its symptoms are delirium, restlessness, confusion, and impairment of mental capacities. Scopolamine is much more likely to produce sedation and amnesia than atropine.
