Pharmacy question?

What is the difference between Coreg CR 20 and Coreg 12.5 mg. Prescribed amount 2 12.5 mg per day?Pharmacy question?
CR resources controlled release, and so, you can take lately one pill per day.
Since you are on the regular Coreg, you own to take two.
There are generic beta blockers.
the cr is intended to be in the order of the same day by day dose in a "controlled release" formulation...i expect the 12.5 is cheaper contained by the long run.
