Why is Micardis prescribed?
Micardis controls high blood pressure. It works by blocking the effects of a hormone called angiotensin II. Unopposed, this substance tends to constrict the blood vessels while promoting retention of salt and water--actions that tend to raise blood pressure. Micardis prevents these effects and thus keeps blood pressure lower. It can be prescribed alone or with other high blood pressure medications, such as diuretics that help rid the body of excess water.
