Description

Atenolol is a medication used to treat certain heart diseases, such as arrhythmias (irregular heartbeats) for dogs and cats. Atenolol is in a class of drugs called beta-blockers. It is used for the treatment of heart disease, including arrhythmias, in cats, dogs, and certain other small animals. It slows the heart rate and causes the heart to work more efficiently. Atenolol works by blocking a specific type of receptor in the heart. This decreases the heart rate, blood pressure, and the workload of the heart. Atenolol tablets are given by mouth, with or without food. Always follow the dosage instructions provided by your veterinarian. If you have difficulty giving the medication, contact your veterinarian. Atenolol will not cure heart disease, but will help manage the symptoms. Atenolol will need to be used on a long-term basis to provide the best results.
