The effects of inhaled beclomethasone dipropionate (Becotide) and sodium cromoglycate on asthmatic reactions to provocation tests

A comparison was made between the effects of prior inhalation of sodium cromogly‐cate or beclomethasone dipropionate on immediate, late and dual asthmatic reactions to provocation challenge tests with a range of allergens. Whereas sodium cromoglycate inhibited immediate and dual asthmatic reactions, beclomethasone dipropionate had no effect on immediate asthmatic reactions, but consistently inhibited late asthmatic reactions.
