How do medications treat hypertension?

There are many types of medications for treatment of hypertension. Diuretics are often the first drug doctors prescribe to flush water and sodium from the body, reducing blood volume. Beta blockers, calcium channel blockers, and angiotensin-converting enzyme (ACE) inhibitors help open blood vessels to promote blood flow. Some of these medications may be combined for greatest effect. Your doctor will talk with you about the right medications for you.
