How Does It Work?

Catapres belongs to a group of medications known as alpha-2 adrenergic agonists. It works by stimulating alpha-2 receptors in the brainstem. This causes a decrease in both blood pressure and heart rate. There is also some evidence that Catapres may decrease certain substances (such as renin or aldosterone) in the body, an action that might also contribute to decreased blood pressure.
