Propranolol is a beta blocker that is used to control the heart rate of pets with irregular heart rhythms. It is also an effective blood pressure reducer. There is some discussion over it’s effectiveness in treating post-traumatic stress disorders and envenomation.
How It Works
Propranolol blocks the beta1 and beta2 receptors of epinephrine and norepinephrine. Epinephrine is commonly called adrenaline and is responsible for the elevated heart rate and "fight or flight" response when your pet is exposed to a stressor or fearful situation. By blocking the receptor for these hormones, the heart rate is decreased, the heart’s oxygen requirement is reduced, and the blood pressure is reduced, leaving you a calm pet with an unstressed heart.
Keep tablets in a tightly sealed container at room temperature.
Give the dose as soon as possible. If it is almost time for the next dose, skip the missed dose, and continue with the regular schedule. Do not give your pet two doses at once.
