Competitive muscarinic receptor antagonist. Increases heart rate (vagolytic), reduces secretions, and mydriasis.
Tachycardia, ileus, urinary retention. Increases myocardial oxygen demand. Rabbits have high atropinase activity — may need higher/more frequent doses or use glycopyrrolate instead.
Species-specific contraindications and adverse-reaction reports for dog may differ from canine / feline reference data — consult the primary citations listed with each rule.
Why a species-specific page? Atropine pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in dog — the rules above are the citations specific to this species, not generic recommendations.
