Mechanism of Action

Competitive muscarinic receptor antagonist. Increases heart rate (vagolytic), reduces secretions, and mydriasis.

Side effects & warnings

Tachycardia, ileus, urinary retention. Increases myocardial oxygen demand. Rabbits have high atropinase activity — may need higher/more frequent doses or use glycopyrrolate instead.
