How it works
LisinoprilCatapres
Zestril (Lisinopril) is an angiotensin converting enzyme (ACE) inhibitor. It blocks a chemical that tightens blood vessels. This makes blood vessels relax, which lowers blood pressure and allows more blood and oxygen to get to your heart and other organs.Catapres (Clonidine) is an alpha-2 agonist. It works in the brain to tell your blood vessels to relax, and it lowers the activity of certain stress hormones. This lowers blood pressure.
