Corgard is a prescription medicine commonly used for the treatment of high blood pressure and angina. It comes in tablet form and is typically taken once a day. As a beta blocker, it works by blocking beta receptors in the body and causing the reverse effect of stress hormones. Some of the most common side effects reported with this medication include fatigue, dizziness, and bradycardia.
Corgard® (nadolol) is a prescription medication approved to treat high blood pressure (known medically as hypertension) and angina (chest pain due to inadequate blood supply to the heart).

Corgard belongs to a group of drugs called beta-adrenergic blocking agents, more often known as beta blockers. As the name implies, these medications block beta receptors in the body. Beta receptors are located in a number of places within the body, including the heart and blood vessels. Stress hormones (such as adrenaline) bind to these receptors and cause certain reactions in the body, such as:
- Increased heart rate
- Increased force with which the heart pumps blood
- Higher blood pressure (both systolic blood pressure and diastolic blood pressure)
- Constricted blood vessels.
By blocking beta receptors, Corgard causes the reverse effect of stress hormones. It decreases the heart rate, blood pressure, and the workload of the heart. This means that the heart requires less blood and oxygen to work properly.
