What is Atenolol?

Atenolol is a beta-blocker used to treat certain heart conditions such as arrhythmias. It may also be used to lower blood pressure and treat enlarged hearts in cats. Atenolol requires a prescription from your veterinarian.

For:

Cats and Dogs

Benefits:
  • Treats cardiovascular diseases and conditions (hypertension, coronary heart disease, arrhythmias, and angina (chest pain))
  • Also, lowers blood pressure and treats enlarged hearts in cats

How it Works:

Atenolol is a beta-blocker that works by affecting the response to nerve impulses in certain parts of the body. As a result, the heart beats slower and decreases blood pressure. When your pet's blood pressure is lowered, the amount of blood and oxygen to the heart is increased.

Cautions:

Tell your veterinarian if your pet is being given any prescription or over-the-counter medicines, as they may interact with Atenolol. If your pet experiences any unusual side effects contact your veterinarian.
