How do inhaled corticosteroids assist in asthma management?

Inhaled corticosteroids play a crucial role in managing asthma primarily by reducing airway inflammation. Asthma is characterized by chronic inflammation of the airways, which leads to symptoms like wheezing, breathlessness, and chest tightness. Inhaled corticosteroids target this underlying inflammation, decreasing the production of inflammatory mediators and cell activity associated with the asthmatic response. This action leads to a reduction in swelling and mucus production in the airways, helping to prevent asthma attacks and improve overall lung function over time.

While the immediate opening of airways is often associated with bronchodilators, inhaled corticosteroids work gradually to control inflammation and prevent future exacerbations. Increasing mucus production would be counterproductive in asthma management, as excessive mucus can lead to blockages and difficulty breathing. Similarly, decreasing lung capacity is not a therapeutic goal; in fact, the focus is on maintaining or improving lung function through effective inflammatory control provided by inhaled corticosteroids.
