Angiotensin-converting enzyme inhibitors (ACE inhibitors)
Angiotensin II antagonists
Calcium channel blockers
Centrally-acting nervous system drugs
Common names include:
Diuretics help the kidneys get rid of excess water and sodium. These medicines are sometimes referred to as “water pills.”
Possible side effects include:
Beta-blockers reduce demands on the heart by reducing the rate and force of contraction and help lower blood pressure.
Beta-blockers may not be the first-line treatment for hypertension.
ACE inhibitors relax the blood vessels and lower blood pressure by blocking the production of a hormone that causes the blood vessels to constrict.
Angiotensin antagonists relax the blood vessels and lower blood pressure by shielding the blood vessels from a hormone that causes the blood vessels to constrict.
Calcium channel blockers relax the blood vessels and lower blood pressure by blocking some activities of heart and blood vessel muscle cells.
Alpha-blockers lower blood pressure by decreasing nerve impulses to the blood vessels. This relaxes the blood vessels and helps lower blood pressure.
Alpha-beta blockers lower blood pressure by decreasing nerve impulses to the blood vessels. They also slow the heart rate and decrease the force of contraction. This decreases the workload of the heart and helps lower the blood pressure.
Nervous system drugs lower blood pressure by controlling nerve impulses and relaxing blood vessels. These drugs can be taken orally. Clonidine is available through a skin patch.
Vasodilators lower blood pressure by directly relaxing blood vessel walls.
