Beta blockers help the heart beat with less speed and force. The heart pumps less blood through the blood vessels with each beat, and blood pressure decreases.
Angiotensin Converting Enzyme Inhibitors (ACEI)
ACE inhibitors keep the body from making a hormone called angiotensin II, which causes blood vessels to narrow. These medications decrease blood pressure by helping blood vessels constricted by angiotensin II expand and let more blood through.
Calcium Channel Blockers
Movement of calcium into and out of muscle cells is necessary for all muscle contractions. These drugs keep calcium from entering the smooth muscle cells of the heart and blood vessels. This makes the heart beat less forcefully and helps blood vessels relax. As a result, blood pressure decreases.
