m not sure if there is a chart for comparing beta blockers, but as far as I know,
bisoprolol (Emconcor) is about 20 times as strong as
Metoprolol, so 1,25 mg of bisoprolol is approx. similar to 25 mg of metoprolol, which again is about the double strength of propranolol. From what my doctor told me, 12,5 mg of Metoprolol is similar to 20 mg of propranolol, but they have different effects.
