Scopolamine intoxications.

Pure scopolamine intoxications are extremely rare. We treated a series of severe intoxications exclusively caused by scopolamine and due to the intentional mixing of pure scopolamine into drinks. The clinical course and therapy are reported. On the basis of our experience and a survey of literature, we found physostigmine to be an excellent antidote. The symptomatology of the patients confirms that scopolamine has a dose-related stimulant effect on the central nervous system.
