### 寵物主人重要須知 * **僅限急診使用：** 異丙腎上腺素是一種強效、速效的急救藥物。它**只能**由受過訓練的獸醫專業人員在醫院環境中給藥，並需持續監測您寵物的心率和血壓。 * **用途：** 通常作為挽救生命的措施，用於治療危及生命的緩慢心率（心臟傳導阻滯）或（極少數情況下）嚴重的氣喘危機。 * **作用迅速：** 藥物會立即生效，但一旦停止靜脈點滴，藥效會在幾分鐘內消退。這使得獸醫能夠精確控制其效果。 * **副作用：** 由於它會強烈刺激心臟，可能會引起心跳過速、焦慮或發抖。獸醫團隊會密切監測這些情況，並在需要時立即調整劑量。
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。

給藥方式
可能的副作用
- Tachycardia
- Ventricular arrhythmias (highly arrhythmogenic)
- Anxiety and excitability
- Tremors
- Headache
- Weakness
- Vomiting
注意事項與禁忌
- Tachycardias or AV block caused by cardiac glycoside (digoxin) intoxication
- Ventricular arrhythmias that do not require increased inotropic activity
- > **Warning:** Isoproterenol is highly arrhythmogenic (more so than dopamine or dobutamine). Use with extreme caution. * **Disease States:** Use with caution in patients with coronary insufficiency, hyperthyroidism, renal disease, hypertension, or diabetes. * **Shock:** Isoproterenol is **not** a substitute for adequate fluid replacement in shock. * **Pregnancy:** FDA Category C. Animal studies show adverse fetal effects. Use cautiously as a last resort when benefits clearly outweigh risks. * **Lactation:** Rapidly deactivated in the gut, so it is unlikely to pose much risk to nursing offspring.
藥物相互作用
- General Anesthetics (cyclopropane, halogenated hydrocarbons): Increased risk of developing arrhythmias. Propranolol may be administered should these occur.
- Beta-Blockers: May antagonize isoproterenol's cardiac, bronchodilating, and vasodilating effects. Can be used to treat isoproterenol-induced tachycardia, but use with caution in bronchospastic disease.
- Digoxin (Digitalis glycosides): Increased risk of arrhythmias.
- Oxytocic Agents: Hypertension may result if used concurrently.
- Other Sympathomimetic Agents (e.g., phenylpropanolamine): Should not be administered concurrently as increased toxicity may result.
- Theophylline: May increase the risk for theophylline toxicity.
