Corgard Oral

Nadolol is used alone or with other medications to treat high blood pressure (hypertension) and to prevent chest pain (angina). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. In the management of chest pain, nadolol may also help to reduce the frequency of chest pain episodes and improve your ability to exercise.
Nadolol belongs to a class of medications called beta blockers. It works by blocking the action of certain natural substances such as adrenaline (epinephrine) on the heart and blood vessels. This results in a lowering of heart rate, blood pressure, and strain on the heart.
