How it works
BystolicLosartan
Bystolic (Nebivolol) is a selective beta blocker that works specifically on the heart. It lowers blood pressure by slowing down the heart and making it work less to pump.Cozaar (Losartan) 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.
