Atropine
別名: Atrocare, Minims Atropine
Atropine is often used in emergency situations to stabilize your pet's heart rate or as eye drops to dilate the pupil for examination. **Note on Eye Drops:** The ophthalmic solution has a very bitter taste. If the drops drain into the back of the throat, your cat or dog may drool excessively. This is a normal reaction to the taste and is not a sign of toxicity. Protect your pet's eyes from bright light while their pupils are dilated.

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.
