How Cardol works
Cardol belongs to a group of medicines called beta-blockers.
It works by changing the body’s response to some nerve impulses, especially in the heart.
It decreases the heart’s need for blood and oxygen and therefore reduces the amount of work the heart has to do. As a result, it helps the heart to beat more regularly.
This medicine is not addictive.
Cardol is available only with a doctor’s prescription.
