The pharmacist said a generic metoprolol extended release is now in the market because the
patent for Toprol XL has
expired. He showed me the difference between the regular generic metoprolol and generic extended release (succinate, I think). I tried the generic version for several days. It was supposed to be seamless but I felt weird with the generic. It didn't seem to have the same potency as the real Toprol XL. I got some dull neck pain from time to time.
