Daily versus intermittent corticosteroids for the treatment of mild persistent asthma.

Asthma is a chronic disease of the airways in which inflammation causes bronchial hyper-reactivity and attacks of wheezing, dyspnea and chest tightness that are triggered by various agents. It requires both acute treatment of the paroxistical respiratory symptoms with reliever medications and maintenance treatment, which is aimed at achieving an optimal disease control and consists of controller medications with regimens and dosages that are tailored according to disease severity. Inhaled steroids represent the main controller medication and are recommended to be given even in mild asthma on a daily basis in order to improve lung function, reduce asthma exacerbations and symptoms, and improve the quality of life. Intermittent regimens could also be used and the currently discussed study compares these two regimens in terms of clinical efficacy.
