Different drugs act in different ways to bring about a normal blood pressure.

For example -

Diuretics (water pills) help your body get rid of extra sodium (salt) and water so your blood vessels don't have to hold so much fluid.

Beta-blockers make the heart beat slower so that blood passes through your blood vessels with less force.

Angiotensin-converting enzyme inhibitors (also called ACE inhibitors) keep your body from making angiotensin II, a hormone that causes blood vessels to narrow. This relaxes your blood vessels.

Calcium channel blockers (also called CCBs) help keep your blood vessels from constricting (becoming narrow) by blocking calcium from entering your cells.

Centrally acting drugs affect your brain and central nervous system to reduce the nerve impulses that can increase your heart rate and cause your blood vessels to narrow.
