International Nonproprietary Names

Guidance

International Nonproprietary Names (INN) facilitate the identification of pharmaceutical substances or active pharmaceutical ingredients. Each INN is a unique name that is globally recognized and is public property. A nonproprietary name is also known as a generic name.

Mandate

WHO has a constitutional mandate to "develop, establish and promote international standards with respect to biological, pharmaceutical and similar products".

The World Health Organization collaborates closely with INN experts and national nomenclature committees to select a single name of worldwide acceptability for each active substance that is to be marketed as a pharmaceutical. To avoid confusion, which could jeopardize the safety of patients, trade-marks should neither be derived from INNs nor contain common stems used in INNs. The selection and publication of INNs falls under the responsibility of the EMP/RHT/TSN team of the INN Programme.
