Ziac

List of products in the National Drug Code with proprietary name ziac. This combination medication is used to treat high blood pressure (hypertension). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. This product contains two medications. Bisoprolol is a beta blocker that works by blocking the effect of certain natural chemicals (e.g., epinephrine) on the heart and blood vessels. This slows your heartbeat, lowers blood pressure, and reduces strain on the heart. Hydrochlorothiazide is a "water pill" (diuretic) that works by increasing the amount of urine that you make. This causes your body to get rid of extra salt and water, which probably helps to relax the blood vessels so that blood can flow more easily. These two drugs are used together when one medication is not controlling your blood pressure. Using these two drugs together can also reduce the amount of each drug you must take, thereby decreasing the chances of side effects.
