Catapres (Clonidine)

Clonidine General Information

Catapres (Clonidine) is in a class of medications called acting alpha-agonist hypotensive agents. This is indicated for the treatment of hypertension or high blood pressure. Lowering high blood pressure helps prevent heart attacks, strokes, or kidney problems. This medication acts in the brain to lower blood pressure. 

How does Catapres (Clonidine) work?

Clonidine works by stimulating alpha receptors in the brain. This action lessens the nerve signals that are sent from the brain to the blood vessels causing them to narrow and contract. As a result, the blood vessels are allowed to relax and widen. This increases the amount of space in the blood vessels. It also decreases the pressure inside them. This lowers blood pressure.
