During the Consultation, a total of 82 INNs were discussed, including:

60 new INN requests, including 24 for biological substances
21 outstanding requests
1 previously selected proposed INN, against which a formal objection had been raised

As a result of these discussions, 73 new names were selected, which are planned to be published in

List 106 of Proposed INNs, while 6 requests were deferred for future discussion. Three requests were

rejected by the INN experts, as the substances did not conform to the criteria for INN selection. One

amendment is planned to be published in List 106. One INN request has been withdrawn during the

selection process.

Six new stems have been selected and 2 suffixes have been promoted to the pre-stem list.
