International Nonproprietary Name



An International Nonproprietary Name (INN; also known as rINN, for recommended International Nonproprietary Name) is the official non-proprietary or generic name given to a pharmaceutical substance, as designated by the World Health Organization (WHO). The plethora of named proprietary preparations containing a given substance can lead to confusion about the identity of the active ingredient. INNs facilitate communication by providing a standard name for each substance. A similar role is played in chemistry by IUPAC names; however, these are less suited to common usage, being typically very long and unwieldy. WHO issues INN names in English, Latin, French, Russian, and Spanish; Arabic and Chinese versions, although not included in the original scheme, are now also being issued.
