If you have stage 1 high Bp Zone blood pressure, 140/90 to 159/99, then your doctor will most likely prescribe a drug and that typically will be a thiazide diuretic. The diuretic will flush excess water and sodium from your system allowing for your blood pressure to go down. In addition, the thiazide diuretic provides some protection from heart attack and stroke. If you are at this stage, it becomes very important that you follow the lifestyle changes necessary to lower your blood pressure.
Failing to do this will lessen the effect of the diuretic and will result in a need for a second, more powerful drug. When you start getting into these drugs you start risking some nasty side effects and your meds will suddenly have an impact on your quality of life. Here is a partial list that might be added to the diuretic:
ACE Inhibitors. These drugs block the production of a hormone that causes the blood vessels to constrict allowing them to relax. Less constriction equals lower blood pressure. ACE Inhibitors include the drugs Capoten, Prinivil and Altace.Angiotensin II receptor blockers. These drugs block the hormone angiotensin which allows the blood vessels to widen in response to pressure on the walls. Commonly prescribed medication in this class includes Cozaar, Benicar and Diovan.
