Peptide Brand Names Explained: A Guide to Common Medicines and Their Active Compounds

When researching peptides, it is common to come across both scientific names and brand names. Understanding the relationship between them can make it much easier to read scientific literature, interpret health news and understand educational resources.

A scientific name identifies the active compound being studied or used in an authorised medicine. A brand name is the commercial name chosen by a pharmaceutical company for a specific authorised product. One active compound may be marketed under more than one brand name.

Semaglutide

Semaglutide is the scientific name of the active compound.

Authorised brand names include:

• Ozempic®
• Wegovy®
• Rybelsus®

Although the brand names are different, they contain the same active compound. They are authorised for different indications and formulations depending on the product.

Tirzepatide

Tirzepatide is the scientific name.

Authorised brand names include:

• Mounjaro®
• Zepbound®

These brand names refer to authorised medicines containing Tirzepatide.

Liraglutide

Liraglutide is marketed under brand names including:

• Saxenda®
• Victoza®

Both products contain the same active compound but are authorised for different clinical uses.

Dulaglutide

The scientific compound Dulaglutide is marketed as:

• Trulicity®

Exenatide

Exenatide has been marketed under brand names including:

• Byetta®
• Bydureon®

Why Are There Different Brand Names?

Pharmaceutical companies develop commercial names to distinguish authorised medicines in the marketplace. The active compound remains the same, while branding, formulation, approved indications and presentation may differ between products.

Why Do Scientific Articles Use Different Names?

Scientific journals almost always use the recognised scientific name of the compound rather than a commercial brand name. This creates consistency across international research and allows scientists to communicate clearly regardless of manufacturer or country.

For this reason, someone reading a research paper may see the scientific name, while a news article or television report may refer to the same compound by its brand name.

Understanding the Difference

Knowing the difference between scientific names and brand names helps readers:

• Understand scientific publications more easily.
• Recognise when different names refer to the same active compound.
• Interpret health news more accurately.
• Navigate biomedical literature with greater confidence.
• Develop a clearer understanding of peptide and metabolic research.

As peptide science continues to advance, understanding the terminology used throughout research and medicine becomes increasingly valuable. Learning the relationship between scientific compounds and their brand names provides an excellent foundation for exploring modern biomedical research.
