In order to make the WHO model formulary compatible with the Model List, entries for the antiretroviral medicines and the other additions to the 12th Model List were prepared immediately after the 2002 meeting of the Expert Committee in time for the release of the first edition of the WHO model formulary at the Annual Congress of the International Pharmaceutical Federation held in Nice, France, in September 2002. The publication was generally very well received. All 7000 printed copies were rapidly disseminated, either by free distribution or through commercial channels, necessitating a second printing in November 2002. A searchable version can be accessed via the WHO web site1 and a CD-ROM version, for use by national and institutional committees, is nearing completion (5). Agreement has been reached with the Royal Pharmaceutical Society of Great Britain for editing and printing future editions of the WHO model formulary.
