OBJECTIVETo compare tulobuterol patch and oral salbutamol sulfate in terms of efficacy and safety in children with mild or moderate acute attack of bronchial asthma.

METHODSA total of 92 children with mild and moderate acute asthmatic attack were randomly divided into salbutamol group (n=46) and tulobuterol group (n=46). Both groups received routine treatment with antihistamine, selective leukotriene receptor antagonist and glucocorticoid. In addition, the salbutamol group was given slow-release capsules of salbutamol sulfate, and the tulobuterol group was treated with tulobuterol patch. The two groups were compared with respect to symptom scores of cough, wheeze, respiratory rate, wheezing sound, three depression sign and peak expiratory flow, as well as adverse events.

RESULTSAs the treatment proceeded, symptom scores decreased in both groups; on the third day of treatment, all symptom scores except cough score showed a significant decrease in both groups (P<0.05), but the tulobuterol group had significantly lower symptom scores than the salbutamol group (P<0.05). On the fourteenth day of treatment, both groups had a significant decrease in cough score (P<0.05), but the tulobuterol group had a significantly lower cough score than the salbutamol group (P<0.05). One child developed hand trembling in the salbutamol group, while no adverse event occurred in the tulobuterol group.

CONCLUSIONSCompared with oral salbutamol sulfate, tulobuterol patch has a better therapeutic efficacy and a higher safety in children with mild or moderate acute asthmatic attack.
