Prazosin and Polythiazide (Systemic)
Brand Names : Minizide
Prazosin and polythiazide
(PRA-zoe-sin and pol-i-THYE-a-zide) combination is used in the treatment of high blood pressure
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.
