How it’s made
Metoprolol is synthesized through a multistep organic chemistry process that starts with a benzene derivative. The active ingredient is typically sold as either the metoprolol tartrate salt (short‑acting) or metoprolol succinate salt (extended‑release). The salt form improves solubility and stability.
Distribution
- United States: The U.S. Food & Drug Administration (FDA) approves each manufacturer separately. The drug is widely available in pharmacies, both brand‑name and generic.
- Europe & Other Markets: The European Medicines Agency (EMA) and national regulatory agencies approve each product. Many generics are available, especially in countries like India, China, and Eastern Europe.
Choosing a Manufacturer
If you’re looking for a specific brand (e.g., Lopressor), you’ll need to check with your pharmacy or healthcare provider, as availability can vary by region and insurance coverage. For generics, most pharmacies will dispense the lowest‑cost option unless a specific formulation (e.g., extended‑release) is required.
Bottom line: Metoprolol is made by a variety of pharmaceutical companies worldwide. The original brand names are produced by Pfizer (Lopressor) and GSK (Toprol‑XL), while many generic versions are manufactured by companies such as Teva, Mylan (Viatris), Sun Pharma, Cipla, and others.
