scopolamine


scopolamine
The structure of scopolamine (hyoscine)
Also called hyoscine and levo-duboisine, an anticholinergic drug related to atropine and widely used in premedication for anesthesia. It tends to be a central-nervous system depressant but otherwise resembles atropine in reducing secretions, gastrointestinal tract activity, and vagus effects on the heart (causing increased pulse rate) and in dilating the pupils of the eyes. It may cause confusion in the elderly. Other common uses include treatment of motion sickness, used as a mild sedative and in Parkinson's disease.
