Metoprolol

What Ingredients Are in Metoprolol?

Metoprolol is a beta blocker medication that includes an active ingredient along with inactive ingredients that help form tablets. Inactive ingredients support manufacturing and delivery but do not provide the intended therapeutic effect.


Active Ingredient

  • Metoprolol

Why Ingredient Lists Can Vary

Metoprolol ingredient lists may differ due to:

  • Product type (immediate-release or extended-release tablet)
  • Dosage strength
  • Salt/form (tartrate vs. succinate)
  • Manufacturer-specific formulations

Because of this, ingredient information should be reviewed at the product level.


Common Brand Names That Contain Metoprolol

Metoprolol is sold under generic labels and branded as Lopressor® and Toprol-XL®. Each product may contain unique inactive ingredients depending on formulation.
