Success of Inhaled Corticosteroids in the Treatment of Non-Asthmatic Respiratory Diseases

Systemic corticosteroids (SCSs) have been widely used to treat various inflammatory respiratory diseases for many years despite the serious complications associated with them. Inhaled corticosteroids (ICSs) have been developed to reduce the harmful adverse effects of SCSs. Since their first introduction, ICSs have been used primarily for the treatment of asthma. However, certain individuals including those with chronic obstructive pulmonary disease or croup may respond to the beneficial effects of ICSs. In this review, we discuss the effectiveness of ICSs in the treatment of non-asthmatic inflammatory respiratory diseases in paediatric and adult populations.
