[Comparative effects of pressurized sodium cromoglycate aerosol and placebo in the treatment of allergic asthma].

28 young adults suffering from allergic perennial asthma have been treated by Lomudal spray or a matching placebo for 4 weeks. Judgment criteria were symptoms evolution, number of crisis, functional respiratory tests before and after treatment, patients and clinician judgments of efficacy and tolerance. Results of functional respiratory tests remind unchanged while symptomatology improved significantly. The total number of crisis was dramatically reduced by sodium cromoglycate treatment compared to placebo. Judgments significantly favoured sodium cromoglycate. Tolerance was excellent in both group.
