Lowering high blood pressure helps prevent heart attacks, strokes, and kidney problems. This may be used alone or in combination with other medications.

How does Corgard (Nadolol) work?

Corgard (Nadolol) works by preventing epinephrine and norepinephrine from binding to beta receptors on nerves. Epinephrine (adrenaline) and norepinephrine are chemicals released within the body that is attached to the receptors on some types of cells. It includes nerves and some muscles. It changes the way the cells function either it stimulates the cells or suppressing them.

By blocking the outcome of epinephrine and norepinephrine, beta-blockers decrease the heart rate and lessen the force of the heart’s contractions. It also reduces blood pressure by relaxing the muscles surrounding the blood vessels.
