How it works
DiltiazemLisinopril
Diltiazem is a calcium channel blocker. It lowers blood pressure by slowing your heart rate and relaxing your blood vessels. Your heart gets more oxygen and doesn't have to work as hard to pump, which can relieve chest pain.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.
