In the print editions of BNF Publications, where there is common information relating to a class of drugs, the shared properties are contained in a drug-class monograph.  Drug-class monographs are highlighted by a circled flag symbol beside the title of the drug-class monograph.  The corresponding individual drug monographs usually follow the drug-class monograph, and are highlighted by a non-circled flag symbol.

For example, the monograph for atenolol will display a flag, indicating that the drug-class monograph for Beta-adrenoceptor blockers (systemic), should be consulted in tandem.  For more information, see How to use BNF publications in print in the preface of the current print publications.
