During the 66th INN Consultation, a total of 172 INN requests were discussed, including:

137 new INN requests, including 85 for biological substances
23 outstanding requests
12 previously selected proposed/recommended INN, against which a formal objection or a

request of substitution had been raised.

As a result of these discussions, 151 names were selected, which are planned to be published in List

120 of Proposed INNs (p.INN), while 7 requests were deferred for future discussion. One application

has been closed since the requested information has not been received. One request was rejected by

the INN Expert Group, as the substance did not conform to the criteria for INN selection. Four

amendments were planned to be published in a forthcoming List of p.INN, 2 requests of substitution

and 1 objection could not be retained as they did not conform to the criteria. Five requests were

withdrawn prior to the Consultation.

Six new stems/substems were selected, 6 suffixes were promoted to the pre-stem list and it was

decided to review the descriptions of 2 stems.
