Is oral albuterol effective for acute cough in non-asthmatic children? A randomised, placebo controlled trial of inhaled salbutamol and beclomethasone for recurrent cough.
Fifty-nine non-asthmatic children with acute cough were randomized to receive oral albuterol or placebo for 7 d. There was a similar, rapid rate of resolution of acute cough for the two groups, but more shaking or trembling in those treated with albuterol (5/30 vs 0/29; p = 0.05). In ambulatory children with acute cough who have no history of asthma and a normal chest examination, oral albuterol does not reduce the frequency or duration of cough. To test the hypothesis that inhaled salbutamol or beclomethasone will reduce the frequency of cough in children with recurrent cough. A secondary aim was to determine if the presence of airway hyperresponsiveness (AHR) can predict the response.
                Randomised, double blind, placebo controlled trial.
                During a coughing phase, 43 children (age 6-17 years) with recurrent cough were randomised to receive inhaled salbutamol or placebo (phase I) for 5-7 days and then beclomethasone or placebo (phase II) for 4-5 weeks, and in a subgroup of children for 8-9 weeks. The children used an ambulatory cough meter, kept cough diaries, and performed the capsaicin cough sensitivity, hypertonic saline bronchoprovocation, and skin prick tests.
                Salbutamol or beclomethasone had no effect on cough frequency or score, irrespective of the presence of AHR.
                Most children with recurrent cough without other evidence of airway obstruction, do not have asthma and neither inhaled salbutamol nor beclomethasone is beneficial.
With the lack of evidence, the routine use of LRTA in treating children with non-specific cough cannot be recommended.
