Corgard (Nadolol) is prescribed either alone or in combination with other medications to address high blood pressure (hypertension) and prevent chest pain (angina). Lowering high blood pressure aids in the prevention of strokes, heart attacks, and kidney problems.

In the management of angina, nadolol may also contribute to reducing the frequency of chest pain episodes and enhancing the ability to engage in physical exercise.

Nadolol belongs to a class of medications known as beta blockers. Its mechanism involves blocking the action of certain natural substances, such as adrenaline (epinephrine), on the heart and blood vessels. This action leads to a reduction in heart rate, blood pressure, and strain on the heart.
