How Does Corgard Work?

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.
