35 adult patients with atopic dermatitis were included in a double-blind crossover trial comparing chromone-2-carboxylic acid, FPL 57787 18 mg x 4, with placebo. Each treatment period lasted for 6 weeks with clinical assessment every 3 weeks. 28 patients completed 3 weeks of each period. Significant differences at the 5% level in favour of FPL 57787 were seen in the group starting on placebo. 17 patients completed the study. After 6 weeks there were no significant differences. 10 patients experienced dyspeptic side-effects. Further studies are warranted on clearly allergic sub-groups of atopic dermatitis patients.
