title: Double-blind crossover study comparing sodium cromoglycate, reproterol, reproterol plus sodium cromoglycate, and placebo in exercise-induced asthma.
abstract: Sixteen patients were included in the analysis of this double-blind crossover study comparing the effect of sodium cromoglycate, reproterol, sodium cromoglycate plus reproterol, and placebo in exercise-induced asthma. Both the sodium cromoglycate and the reproterol-containing treatment significantly inhibited exercise-induced asthma. The best protection is effected by the combination of sodium cromoglycate and reproterol. A synergistic effect of both medications could not be confirmed statistically so that their combined effect is simply additive.
