์์ฉ ๊ธฐ์ : N-butylscopolammonium bromide acts as a **competitive antagonist** at **muscarinic acetylcholine receptors** located on smooth muscle cells. * **Mechanism**: Blocks acetylcholine binding โ prevents intracellular calcium release โ induces profound relaxation of gastrointestinal and urinary smooth muscle. * **Pathway**: Parasympathetic inhibition โ decreased GI peristalsis and reduced rectal pressure. * **Duration**: Visceral antinociceptive and spasmolytic effects are brief, typically lasting 15-20 minutes in horses.

Dosages up to 10X (3 mg/kg) were administered to horses as part of preapproval studies. Clinical effects noted included dilated pupils (returned to normal in 4-24 hours), tachycardia (returned to normal within 4 hours) and dry mucous membranes (returned to normal in 1-2 hours). Gut motility was inhibited, but returned to baseline within 4 hours and normal feces were seen within 6 hours. Two of the four horses treated at 10X dosage developed mild signs of colic which resolved without further treatment.
