์์ฉ ๊ธฐ์ : Aminopentamide acts as a **competitive antagonist at muscarinic acetylcholine receptors (mAChRs)** in the parasympathetic nervous system. By blocking acetylcholine binding, it inhibits parasympathetic tone. * **GI Tract:** โ Decreases smooth muscle contractions (reducing colonic spasms) and reduces gastric acid secretion. * **Systemic:** Compared to atropine, it reportedly has a greater targeted effect on reducing colonic contractions with relatively fewer mydriatic (pupil dilating) and salivary (dry mouth) effects, though classic anticholinergic signs can still occur.

No specific information was located regarding acute overdosage clinical signs or treatment for aminopentamide. Guidelines for atropine overdose may be applied: * **Decontamination:** If recent oral ingestion, empty gut contents and administer activated charcoal and saline cathartics. * **Supportive Care:** Treat clinical signs symptomatically. Fluid therapy and standard treatments for shock may be instituted. **Do not use phenothiazines** as they may contribute to anticholinergic effects. * **Antidote (Severe Cases):** The use of physostigmine is controversial and reserved for extreme agitation or life-threatening supraventricular/sinus tachycardias. Human pediatric dose (reasonable for small animals): 0.02 mg/kg slow IV, repeat q10 minutes until reversal of toxic effects. Physostigmine adverse effects (bronchoconstriction, bradycardia, seizures) may be treated with small doses of IV atropine.
