Lopressor generic name?

What is Lopressor’s generic name?

Lopressor is a brand name for the beta-blocker metoprolol (most commonly metoprolol tartrate) [1].

Metoprolol tartrate vs metoprolol succinate—are they different?

Yes. Lopressor specifically refers to metoprolol tartrate, while other brands may use metoprolol succinate (a different salt and typically different dosing schedules).

Why does the “generic name” matter?

When people ask for Lopressor’s generic name, they usually want the active ingredient. In prescriptions and pharmacy substitutions, the active ingredient is metoprolol (tartrate), even if the brand name is Lopressor [1].
