Sodium cromoglycate: spincaps or metered dose aerosol.

1 Sodium cromoglycate administered as a dry powder inhalation (20 mg/dose) via the Spinhaler was compared with a metered dose aerosol (2 mg/dose) in an eight week double dummy double blind crossover trial in 29 asthmatic children. 2 The powder formulation was associated with significantly less symptoms (night wheeze, night cough, day wheeze, day cough, activity) and bronchodilator intake; and significantly greater weight gain than aerosol therapy. There were no significant differences in morning or evening peak flow measurements on the two treatments. 3 The powder may be more effectively inhaled than the aerosol or the dose of the aerosol may not be large enough.
