Used in the treatment of certain heart diseases
Can help to lower blood pressure
Slows and regulates heart rate so that the heart can work more efficiently

Atenolol is a prescription medication used to treat certain heart conditions such as arrhythmias. This beta-blocker can also be used to lower blood pressure and treat enlarged hearts in cats. Atenolol functions by slowing and regulating your pet's heart rate to make the heart work more efficiently. It is appropriate for use in dogs, cats, and ferrets.

Atenolol is a beta-blocker that lowers heart rate, blood pressure, and over-activity of the heart, thus allowing for a regular heartbeat and better heart function.

Atenolol is the generic alternative to Tenormin.

The medicine can be used in cats, dogs and ferrets. The dosage of medication and also the frequency of administration are largely determined by the severity of the condition as well as the nature of response the animal exhibits towards the treatment. The usual dose given to dogs is 0.125 to 0.5 mg per pound (0.25 to 1.0 mg/kg) once to twice a day. The total daily dose is often 6.25 to 25 mg/dog. The usual dose for cats is 1 mg per pound (2 mg/kg) once everyday. The total daily dose in cats is often 6.25 to 12.5 mg once or twice daily.

Atenolol 25mg

Atenolol belongs to general class of cardiac drug that is used in veterinary medicine and is indicated in treating certain heart diseases like arrythmias. During the course, the medicine controls the heart rate, lowers blood pressure and deals with rhythm irregularity in animals like cats, dogs and ferrets. In certain cases, the medication is also used in cats suffering from enlarged hearts. Atenolol, the active ingredient in the medicine is a beta-blocker, which effectively deals with certain conditions affecting the heart. When administered, this oral medication helps in controlling abnormalities in the heart as well as in the blood pressure by blocking certain nervous system impulses. The medicine is available by prescription in capsule form.

Side effects may include lethargy, difficulty exercising, low blood pressure which would cause fainting, weakness, or dizziness, loss of appetite, nausea, diarrhea, behavior change, and low blood sugar.

Atenolol may constrict the bronchi, resulting in coughing, wheezing, or difficulty breathing.

An improper dose of Atenolol can cause the heart rate to be too slow.

If your pet experiences an allergic reaction (symptoms may include swelling, hives, difficulty breathing, itching, etc.) or any of the above symptoms, contact your veterinarian.

Atenolol should not be used in pets with heart block, bradycardia (slow heart rate), and some types of heart failure. Use with caution in diabetic pets or those with kidney disease.

Use with caution in animals with some types of lung disease such as asthma.

Atenolol should not be used in pets allergic to it, or pets who have had reactions to other beta-blockers.

Possible interactions may occur with the following drugs: albuterol (Ventolin), anesthetic agents, cimetidine, epinephrine, furosemide, hydralazine, insulin, metaproterenol, nonsteroidal anti-inflammatories (ex. aspirin, carprofen), other heart medications (digoxin, diltiazem, verapamil), phenothiazines (tranquilizers), phenylpropanolamine, prazosin, and terbutaline.

Tell your veterinarian about any other medications, vitamins, or supplements that your pet is taking.

In no case should the medicine be tried on animals that are hypersensitive to atenolol or any other beta-blockers. Special care must be taken in using the medication in animals undergoing any kind of kidney, lungs or heart abnormalities or diabetic attacks. It is not advised to give the medication with metaproterenol, terbutaline, epinephrine and phenylpropanolamine, as this may result in reduced effects. Care must be taken in using the medicine in an animal that is already under another medication. Medication overdose might bring about certain adverse reactions like lethargy, cough, breathing problems or even change in the behavior of the animal.

Certain animals might tend to develop side effects to the medicine when administered. The reported side effects include lethargy, hypoglycemia, depression and hypotension. There can also be a drop in the heart rate and even diarrhea, though only in rare cases.

Follow the directions provided by your veterinarian.

This medication is usually given once or twice daily to dogs and once daily to cats.
