Mechanism of action
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.
Side effects & warnings
Tachycardia is common and expected. Transient ileus possible. Contraindicated in mechanical GI obstruction. Used primarily in horses for colic. Monitor heart rate during administration.

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 cat — the rules above are the citations specific to this species, not generic recommendations.
