School of INN

The School of INN is a WHO International Nonproprietary Name Programme initiative.
Its role is to educate the pharmaceutical and medical students, as well as all other INN stakeholders on how to design and construct an INN. It also provides information to healthcare professionals and patients on how to interpret an INN. The school fosters the science of nomenclature and helps to cultivate a future generation of INN experts.

MedNet INN services
The WHO MedNet offers on-line information services related to INNs which are free of charge to its members.
As a Member of MedNet INN, you will be able to search the INN database for INN names, for names published on recommended or proposed lists, and display the equivalent of the Latin INN name in Arabic, Chinese, English, French, Spanish and Russian. You will also be informed about any existing national names, ATC codes if assigned to INNs and the basic chemical information. The INN Status query allows for tracking the status of INNs within the INN process.

The "How to.." session offers on-line information on how to access and use INN service like the advance search tool, the INN online application and others.

The INN Expert Group has adopted a nomenclature for COVID-19 vaccine substances dedicated to SARS-CoV-2 variants of concern (VOCs). The WHO INN Programme encourages vaccine developers to submit INN requests for COVID-19 vaccine substances including those directed against SARS-CoV-2 VOCs and urges regulatory authorities to facilitate their implementation. Please consult the corresponding document titled “International Nonproprietary Names for Variant COVID-19 Vaccine Active Substances” for further details.
