阿托品
別名: Atrocare, Minims Atropine
藥物類別: Anticholinergic / Parasympatholytic
阿托品通常用於緊急情況下穩定寵物的心率，或作為眼藥水來放大瞳孔以進行檢查。 **眼藥水注意事項：** 眼藥水味道非常苦。如果藥水流到喉嚨後部，您的貓或狗可能會大量流口水。這是對味道的正常反應，而不是中毒的跡象。在寵物瞳孔放大的期間，請保護牠們的眼睛免受強光照射。
劑量必須由獸醫依你寵物的個別情況決定。切勿在沒有獸醫指導下給予人類藥物或其他寵物的處方藥。

注意事項與禁忌

- Atropine has a **slow onset of action** (10 min IM, 2-3 min IV); therefore, it is important to wait for an adequate period of time for the desired effect before redosing. > **Clinical Pearl:** The ophthalmic solution tastes very bitter. If it drains through the nasolacrimal duct into the mouth, it can cause profound hypersalivation, particularly in cats and some dogs. Blurred vision from mydriasis may worsen recovery from anaesthesia.
