Lowers blood pressure. Diovan (Valsartan) is a good blood pressure-lowering medicine that protects kidney function like an ACE inhibitor, but with fewer side effects. Lowers blood pressure and makes it easier to urinate. Prazosin is used mostly to make urination easier for men with an enlarged prostate, but it can cause dizziness. How it works Diovan (Valsartan) is an angiotensin receptor blocker (ARB). It blocks a chemical that tightens blood vessels. This makes blood vessels relax, which lowers blood pressure and allows more blood and oxygen to get to your heart and other organs. Prazosin is a selective alpha blocker. It lowers blood pressure by relaxing blood vessels. It also relaxes the urethra and prostate, which makes it easier to urinate. Type of medication Antihypertensive
