title: The effect of sodium cromoglycate, beclomethasone diproprionate and salbutamol on the ventilatory response to cotton dust in mill workers.
abstract: A double-blind placebo controlled study of sodium cromoglycate, beclomethasone dipropionate and salbutamol by inhalation was designed to test their effect on respiratory symptoms and changes in ventilatory capacity in cotton mill workers. All three drugs showed some beneficial effect. Salbutamol was the most effective drug studied, in all groups of workers. Beclomethasone dipropionate was also significantly effective particularly in workers with byssinosis or exertional dyspnoea. Sodium cromoglycate was the least effective of the three. Possible mechanisms of action of these drugs are described.
