How it works
LosartanBisoprolol
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.Zebeta (Bisoprolol) 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.
