Question:
Answers:
They tend to serve various purposes.. I am assuming that you know what causes high blood pressure, etc. Thus, the medicines can all be classified or put into the class of a antihypertensive drug(s). Some of these are:
Diuretics: These drugs help your body get rid of extra sodium and fluid so that your blood vessels don't have to hold so much fluid.
Beta blockers: These drugs block the effects of adrenaline.
Alpha blockers: These drugs help your blood vessels stay open.
ACE inhibitors: These drugs prevent your blood vessels from constricting by blocking your body from making angiotensin II. Angiotensin II is a chemical that constricts blood vessels.
Calcium channel blockers: These drugs help prevent your blood vessels from constricting by blocking calcium from entering your cells.
