Hi and thanks for the query.

Metoprolol tartrate (Lopressor) is a regular, immediate-release tablet, while metoprolol succinate (Toprol XL) is an extended-release. The active ingredient in both is the same, that is the beta blocker Metoprolol. The difference is that Metoprolol succinate is an extended-release version of metoprolol, so it remains in the bloodstream and controls blood pressure for a full 24 hours. Metoprolol tartrate does not stay in the bloodstream for 24 hours.

Hope this helps.
