A short description is given of the interplay between the pharmaceutic
al industry and its critics regarding the rational use of medicines si
nce the 1960s. This was especially vigorous in the developing countrie
s but also had ramifications in the industrialized world. The initiati
ves taken by the World Health Organization in starting a dialogue betw
een the industry representatives in the International Federation of Ph
armaceutical Manufacturers Associations and the critical voices of Hea
lth Action International are specially emphasized. The recent developm
ents in the therapy of primary hypertension and peptic ulcer are discu
ssed briefly as examples of the rapid changes in what should be ration
al in pharmacologic treatment of disease.
