[Comparative advertising and medicine: changing of regulations].

Directive 97/55/EC of October 6, 1997 has just amended Directive 84/450/EEC concerning misleading advertising in order for it to encompass comparative advertising. The purpose is to harmonize regulations regarding comparative advertising. Although the basic terms of this Directive are very similar to those imposed in France by the law of January 18, 1992, its transposition should, however, require changes to be made to French law.
