Comparison of the long-term effect of fenoterol hydrobromide and theophylline syrups in pre-school asthmatic children

Abstract

Eleven asthmatic children less than six years were treated double-blind for eight weeks with fenoterol, theophylline or placebo syrups. Both active drugs significantly decreased the incidence of cough compared to placebo. Nocturnal symptoms and wheezes were also reduced but were not improved to a statistically significant degree.
