Data Changes
The active ingredient for extended release drugs formerly listed as metoprolol tartrate has been changed to metoprolol succinate. Previously, the basis of strength substance (BoSS), metoprolol tartrate, was used in the normalized name for these drugs. Beginning with this release, the normalized names will now use metoprolol succinate instead. RXCUIs for these concepts will not change; however, the RXAUIs for the normalized names will change.
