Short-acting muscarinic antagonist that blocks the sphincter pupillae muscle, causing mydriasis. Also causes cycloplegia (ciliary muscle paralysis).
Short duration (4-8 hours). Used for diagnostic fundoscopy. May increase IOP — CONTRAINDICATED in glaucoma. Not for therapeutic mydriasis (use atropine for that). Rapid onset (15-20 min).
Species-specific contraindications and adverse-reaction reports for cat may differ from canine / feline reference data — consult the primary citations listed with each rule.
Why a species-specific page? Tropicamide pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in cat — the rules above are the citations specific to this species, not generic recommendations.
