Publishing INN Lists

All newly selected names are published, after informing the originator of the request in the journal WHO Drug Information. Two proposed and two recommended lists are published per year. The lists are trilingual, in English, French and Spanish, and include Latin INNs.

All INNs are published in a cumulative list of INNs *, which is updated periodically and includes INNs in Latin, English, French, Spanish, Arabic, Chinese and Russian, as well as reference to other common names. At present, more than 8,000 INNs have been published.
