Isoproterenol
別名: Isuprel, Imuprel, Isolin, Lenoprel, Norisodrine Aerotrol, Proterenal, Saventrine, Vapo-iso
### Important Information for Pet Owners * **Emergency Use Only:** Isoproterenol is a potent, fast-acting emergency medication. It is **only** administered by trained veterinary professionals in a hospital setting where your pet's heart rate and blood pressure can be continuously monitored. * **Purpose:** It is typically used as a life-saving measure to treat dangerously slow heart rates (heart block) or, rarely, severe asthma crises. * **Rapid Action:** The drug works immediately but wears off within minutes once the IV drip is stopped. This allows the veterinarian to precisely control the effects. * **Side Effects:** Because it strongly stimulates the heart, it can cause a rapid heart rate, anxiety, or tremors. The veterinary team will monitor closely for these and adjust the dose instantly if needed.
劑量必須由獸醫按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

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.
