    Abstract

    The prophylactic inhalation of disodium cromoglycate lessens the exacerbations which occur in some asthmatic patients after voluntary hyperventilation. Reasons are given for considering this to be a possible mechanism for certain types of emotional exacerbation of the disease and for disodium cromoglycate giving sypmtomatic relief of asthma disproportionate to the improvement in routine measurements of ventilatory capacity. It is suggested that one clinical indication for giving disodium cromoglycate is to observe whether a fall in FEV1 occurs after two minutes hyperventilation.
