In which condition are inhaled corticosteroids primarily used?

Inhaled corticosteroids are primarily used in chronic asthma because they are effective in reducing airway inflammation, which is a hallmark of this condition. Asthma is characterized by chronic inflammation of the airways, leading to symptoms such as wheezing, shortness of breath, and chest tightness. By using inhaled corticosteroids, patients can manage and control this inflammation, leading to fewer asthma exacerbations and improved lung function. These medications help maintain long-term asthma control and are considered a cornerstone of asthma management.

In contrast, while inhaled corticosteroids may sometimes be used in COPD management, particularly in patients with frequent exacerbations, their primary and most established role is in asthma therapy. Acute bronchitis is generally treated with supportive measures, and pneumonia typically requires antibiotics rather than corticosteroids unless there is significant airways inflammation involved, which is uncommon in these cases.
