During the Consultation, a total of 112 INNs were discussed, including:

As a result of these discussions, 102 new names were selected, which are planned to be published in

List 109 of Proposed INNs, while 7 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 109. One new stem have been selected and 8 suffixes

have been promoted to the pre-stem list.
