Prazosin and polythiazide - PRA-zoe-sin and pol-i-THYE-a-zide combination is using in the treat of high blood pressure - hypertension.
High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart and kidneys resulting in a stroke, heart failure, or kidney failure. High blood pressure may also increase the risk of heart attacks. These problems may be less likely to occur if blood pressure is controlled.
Prazosin works by relaxing blood vessels so that blood passes through them more easily. The polythiazide in this combination is a thiazide diuretic - water pill that helps to reduce the amount of water in the body by increasing the flow of urine. Both of these actions help to lower blood pressure.
