[Modes of administration of inhaled corticosteroids in mild to moderate persistent asthma]

Abstract

Inhaled corticosteroids are the treatment of choice for asthma. However, poor compliance by patients is one of the principal difficulties forced by clinicians. Thus, it seems important to propose the minimal daily number of doses. This study has compared the various modes of administration of inhaler corticosteroids and was carried out in patients with mild to moderate persistent asthma. Thus, comparing two to four doses per day shows an identical efficacy if the dose is less than 800 micrograms per day. At higher doses only two studies have been carried out and there are discordant results. The studies compare two doses versus one single dose per day and equally disagree with numerous works in favor of a single daily dose. In the single study carried out for at least twelve months the twice daily dose was the most effective. Thus it seems reasonable to suggest a single dose for mild persistent asthmatics. For moderate persistent asthmatics the choice between a single or twice daily dose would depend on the therapeutic compliance of the patient.
