[Beclomethasone dipropionate seasonal allergic rhinitis treatment of children. A double blind cross over study (author's transl)].

In a double-blind cross over study on 25 children with seasonal allergic rhinitis treatment with Beclomethasone dipropionate (BDP)-Aerosol was found more effective than placebo. 17 children preferred BDP, two the placebo-aerosol, while 6 had no preferrence. During a period with very high pollen concentrations in the air the effect of BDP-therapy was no longer sufficient.
