Once-daily inhaled corticosteroids in children with asthma: dry powder inhalers.

摘要

The cornerstone of pharmacological management of asthma in childhood is inhaled corticosteroids. These drugs are intended for long term treatment and, consequently, compliance is a major issue. Once-daily administration of maintenance medication would simplify treatment and it is likely that it would lead to better compliance. Moreover, the excellent safety profile of inhaled corticosteroid treatment tailored to disease severity may, theoretically, be further improved with once-daily administration. Studies comparing inhaled corticosteroids given once or twice daily to patients with asthma indicate that unstable asthma is best treated with at least 2 daily doses. On the other hand, it has been demonstrated that, if the asthma is stabilised, most children can be treated with inhaled corticosteroids once daily without loss of efficacy. Thus, the data suggest that newly diagnosed asthma, or asthma after deterioration, should first be reliably controlled with inhaled corticosteroids divided into at least 2 daily doses. Once-daily maintenance treatment should then be tried with the aim of improving compliance and quality of life. A dry powder inhalation device is probably the best choice for children from the age of 5 years.
