Angiotensin II Receptor Blockers (ARBs)
Angiotensin II receptor blockers (ARBs) are a newer type of medication for blood pressure that protect your blood vessels from angiotensin II. As a result, with this type of medicine, the blood vessels relax and become wider, and your blood pressure goes down.
Some examples of ARBs include:


Calcium Channel Blockers (CCBs)
Calcium channel blockers keep calcium from entering the muscle cells of the heart and blood vessels. This reduces the heart rate and causes the blood vessels to relax. In turn, blood pressure goes down.
CCBs used as blood pressure medications include:
Alpha Blockers
Alpha blockers reduce nerve impulses to blood vessels. This enables blood to pass through the vessels more easily, resulting in lower blood pressure.
Alpha blockers used for treatment of high blood pressure include:
Alpha-Beta Blockers
Alpha-beta blockers work in the same fashion as alpha blockers, but they also slow down the heart rate (they are similar to beta blockers in this regard). This type of blood pressure drug results in less blood being pumped through the blood vessels, so the blood pressure goes down. Carvedilol (Coreg®) is an alpha-beta blocker used to help manage high blood pressure.
