Metoprolol, commonly known as Lopressor
is a beta blocker. This medication
is used in the treatment of high blood pressure, angina (chest pain, usually caused by lack of oxygen to the heart due to clogged arteries, which can cause PVCs), and heart attack.
I've taken Metoprolol for 6 years, and find it ineffective for treating PVC's, at least for me. I was extremely effective in lowering my blood pressure, and slowing my resting heart rate.
