The creation of the ATC/DDD methodology was an</p><p align="left">important basis for presenting drug utilisation statistics in a sensible way. Norway was in 1977 also the</p><p align="left">first country to publish national drug utilisation statistics from wholesalers on an annual basis. The</p><p align="left">combination of these activities in Norway in the seventies made us a pioneer country in the area of drug</p><p align="left">utilisation research. Over the years, the use of the ATC/DDD methodology has gradually increased in</p><p align="left">countries outside Norway. Since 1996, the methodology has been recommended by WHO for use in</p><p align="left">international drug utilisation studies. The WHO Collaborating Centre for Drug Statistics Methodology</p><p align="left">in Oslo handles the maintenance and development of the ATC/DDD system. The Centre is now responsible</p><p align="left">for the global co-ordination. After nearly 30 years of experience with ATC/DDD, the methodology</p><p align="left">has demonstrated its suitability in drug use research. The main challenge in the coming years is to</p><p>educate the users worldwide in how to use the methodology properly.</p></span></span>
