High Blood Pressure Medication (cont.)

Examples of ACE inhibitors include:

Angiotensin receptor blockers (ARBs)

Angiotensin II receptor blockers (ARBs) are medications that block the action of angiotensin II by preventing angiotensin II from binding to angiotensin II receptors on the muscles surrounding blood vessels. As a result, blood vessels enlarge (dilate), and blood pressure is reduced.

Examples of ARB drugs include:

Beta-blockers

Beta blockers are drugs that block norepinephrine and epinephrine (adrenaline) from binding to both beta 1 and beta 2 receptors on organs and muscles, including the muscles that cause blood vessels to narrow and the heart to beat. By blocking the effect of norepinephrine and epinephrine, beta blockers reduce blood pressure by dilating blood vessels and reducing heart rate. They also may constrict air passages because stimulation of beta receptors in the lung cause the muscles that surround the air passages to contract.
