title: Beclomethasone dipropionate aerosol compared with dry powder in the treatment of asthma.
abstract: In a double-blind trial, beclomethasone dipropionate inhaled as a dry powder in doses of 200 micrograms three times a day was compared with the conventional aerosol of 100 micrograms three times a day, each for a period of 4 weeks. Neither the dry powder nor the aerosol showed any significant advantage over each other in terms of ventilatory function. Plasma cortisol levels were unaltered with the two medications in spite of the doubled dose of the corticosteroid powder. Choice of one or the other method of administration of medication depended on patient preference and the ease with which he could familiarize himself with either technique.
