Atenolol

Why has my veterinarian prescribed this medicine?

Atenolol is primarily used to treat heart disease in cats and dogs and to lower blood pressure. It is a beta1-blocking agent. Atenolol decreases the heart's need for blood and oxygen and therefore reduces the amount of work the heart must do. It also helps the heart beat more regularly.
