How does atropine work on the eye?
This medication is used before eye examinations (e.g., refraction) and to treat certain eye conditions (e.g., uveitis). It belongs to a class of drugs known as anticholinergics. Atropine works by widening (dilating) the pupil of the eye.

Why is atropine poisonous?
Ingestion of as little as a few drops of atropine in eye drop formulation can cause anticholinergic, or more specifically antimuscarinic, toxicity. The antimuscarinic toxidrome results from blockade of the neurotransmitter acetylcholine at central and peripheral muscarinic receptors.
Does atropine slow heart rate?
Atropine can cause bradycardia. Atropine has complex effects on heart rate: At low doses, atropine blocks M1 acetylcholine receptors in the parasympathetic ganglion controlling the SA node. This decreases heart rate (Bernheim 2004).
