Atenolol
別名: Tenormin
- **Consistency is Key:** To be effective, your pet must receive all doses exactly as prescribed by your veterinarian. - **Do Not Stop Abruptly:** Never stop this medication suddenly without consulting your veterinarian, as this can cause dangerous spikes in heart rate and blood pressure. If the medication needs to be stopped, it must be withdrawn gradually. - **Monitor for Side Effects:** Notify your veterinarian immediately if your pet becomes unusually lethargic, shows exercise intolerance, develops shortness of breath or a cough, or exhibits a sudden change in behavior or attitude. - **Pill Splitting:** Tablets may be crushed or split into quarters or halves for appropriate dosing as directed.
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。

- > **Withdrawal Warning:** Exacerbation of symptoms has been reported following abrupt cessation of beta-blockers. It is highly recommended to withdraw therapy gradually in patients who have been receiving the drug chronically. * **Renal Impairment:** Use cautiously in patients with significant renal insufficiency as the drug is primarily excreted unchanged in the urine. * **Endocrine:** Can mask clinical signs associated with hypoglycemia and thyrotoxicosis. Use cautiously in labile diabetic patients as it can cause hypo- or hyperglycemia. * **Cardiac:** Use cautiously in patients with sinus node dysfunction. Non-specific beta-blockers are generally contraindicated in patients with CHF unless secondary to a tachyarrhythmia responsive to beta-blocker therapy.
藥物相互作用
- Anesthetics (myocardial depressants): Additive myocardial depression may occur with concurrent use.
- Calcium-Channel Blockers (e.g., diltiazem, verapamil, amlodipine): Concurrent use should be done with caution due to additive negative inotropic effects, particularly in patients with preexisting cardiomyopathy or CHF.
- Clonidine: Atenolol may exacerbate rebound hypertension after stopping clonidine therapy.
- Furosemide, Hydralazine, or other hypotensive drugs: May increase the hypotensive effects of atenolol.
- Phenothiazines: Concurrent use may exhibit enhanced hypotensive effects.
- Reserpine: Potential for additive effects including hypotension and bradycardia.
- Sympathomimetics (e.g., metaproterenol, terbutaline, epinephrine, phenylpropanolamine): May have their actions blocked by atenolol, and they may in turn reduce the efficacy of atenolol.
