Quaternary ammonium anticholinergic that blocks muscarinic receptors on GI smooth muscle, reducing spasm and motility. Does not cross the blood-brain barrier, limiting central side effects.
Tachycardia is common and expected. Transient ileus possible. Contraindicated in mechanical GI obstruction. Used primarily in horses for colic. Monitor heart rate during administration.
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? N-Butylscopolammonium Bromide 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.
