Drug Information

Atropine is an alkaloid (a family of chemicals with pharmacologic activity and a common structure) that affects the nervous system. It is found in deadly nightshade (Atropa belladonna) and other plants. Some effects of atropine include blurred vision, dilated pupils, constipation, dry mouth, and dry eyes.

Atropine is available as a prescription drug, synthesized in the laboratory. It is used to help restore or control heart function. It is used in combination with other drugs to treat other health problems including diarrhea and excessive salivation (saliva production). Atropine drops (Isopto® Atropine and others) are used to dilate pupils for eye exams.
