Terbutaline
別名: Brethine, Bricanyl, Monovent
- **Purpose:** Terbutaline is used to open up the airways in the lungs, making it easier for your pet to breathe. - **Administration:** Give exactly as prescribed by your veterinarian. Do not stop the medication abruptly unless instructed. - **Side Effects:** You may notice your pet's heart beating faster than normal, mild tremors, or jitteriness/nervousness. These effects are usually mild and temporary. - **When to Call the Vet:** Contact your veterinarian immediately if your pet's breathing worsens, if they collapse, or if they become acutely ill.
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
- Increased heart rate (tachycardia)
- Tremors
- CNS excitement (nervousness)
- Dizziness
- Sweating (reported in horses after parenteral injection)
- Transient hypokalemia
- Tachycardia
- Muscle tremors
- Restlessness or excitement
- Hypokalemia (with high doses or prolonged use)
- Hypertension or hypotension
注意事項與禁忌
- Known hypersensitivity to terbutaline
- Heart disease (especially congestive heart failure or cardiomyopathy)
- Known hypersensitivity to terbutaline or sympathomimetic amines
- Severe cardiac arrhythmias
- Hypertrophic cardiomyopathy (relative contraindication)
- Use with extreme caution in patients with **diabetes mellitus, hyperthyroidism, hypertension, seizure disorders, or cardiac disease** (especially with concurrent arrhythmias). > **Note:** Terbutaline can cause transient hypokalemia. If an animal is susceptible to developing hypokalemia, additional serum potassium monitoring should be performed early in therapy.
藥物相互作用
- Inhalation Anesthetics (e.g., halothane, isoflurane, methoxyflurane): May predispose the patient to ventricular arrhythmias, particularly with preexisting cardiac disease; use cautiously.
- Beta-Adrenergic Blocking Agents (e.g., propranolol): May antagonize the bronchodilating and cardiovascular actions of terbutaline.
- Digoxin: Concurrent use with digitalis glycosides may increase the risk of cardiac arrhythmias.
- Monoamine Oxidase Inhibitors (MAOIs): May potentiate the vascular effects of terbutaline.
- Other Sympathomimetics: May increase the risk of developing adverse cardiovascular effects.
- Tricyclic Antidepressants: May potentiate the vascular effects of terbutaline.
- Beta-blockers (e.g., propranolol): Antagonize the bronchodilating effects of terbutaline
- Sympathomimetics: Additive cardiovascular toxicity and CNS stimulation
- Inhalant anesthetics (e.g., halothane): Sensitize the myocardium, increasing the risk of severe arrhythmias
- Tricyclic antidepressants (TCAs) / MAOIs: May potentiate vascular effects
