Virtually nothing ... it's chemistry! Metoprolol is the active drug and Metoprolol Succinate is the "salt" which is the form of the drug our bodies can use... Confused!
There are often several different "salts" of a drug that drug companies make eg Metoprolol tartrate. Some salts have slightly different qualities eg the tartrate salt may dissolve quicker than the succinate salt
Metoprolol is always made in tablet form as a salt. (some drug companies call it by the full name ( metoprolol succinate - salt included) others don't mention the salt (metoprolol)
Hope that helps.
