2.3. International Nonproprietary Names for pharmaceutical substances

The Committee was informed of the current activities of the programme on International Nonproprietary Names (INNs) for pharmaceutical substances (4). It endorsed the "Guidelines for the graphic representation of chemical formulae" that had been prepared (Annex 1), which would promote harmonization in the presentation of structural formulae.
