Clonidine Drug Class
A part of the alpha-2 adrenergic agonist drug class, clonidine works in several different ways. It works to decrease both blood pressure and heart rate by stimulating alpha-2 receptors in the brain stem. It may also work to lower blood pressure by decreasing certain substances (such as renin or aldosterone) in the body. When used in an epidural to treat cancer pain, clonidine works by blocking pain signals from reaching the brain.
