An international nonproprietary name (INN) is the unique generic name assigned to a pharmaceutical substance by the World Health Organization. It is public property, cannot be trademarked, and is intended to be usable in any language.[1]

INNs are constructed from a distinctive prefix, chosen to be pronounceable and unlike existing names, and a stem indicating pharmacological class. The stem is the informative part: -glutide denotes a GLP-1 analogue, and -tide more broadly denotes a peptide.[1]
