Which medication class is commonly used for asthma prophylaxis?

Corticosteroids are commonly used for asthma prophylaxis due to their potent anti-inflammatory properties. In asthma management, the underlying issue is airway inflammation, which leads to symptoms such as wheezing, coughing, and difficulty breathing. Corticosteroids help to reduce this inflammation, thereby preventing asthma attacks and improving overall lung function.

Inhaled corticosteroids, in particular, are frequently prescribed as a first-line treatment for long-term control of asthma. They work by inhibiting the release of inflammatory mediators and reducing the overall inflammatory response in the airways. Regular use of inhaled corticosteroids can lead to improved asthma control and a reduction in the frequency of acute exacerbations.

Other medication classes, while relevant for managing different aspects of respiratory conditions, are not primarily used for asthma prophylaxis. For example, antitussives are intended to suppress cough, xanthine derivatives are less commonly used and often used for acute relief rather than prophylaxis, and decongestants primarily relieve nasal congestion and wouldn’t address the inflammatory process underlying asthma. This distinction underscores the significance of corticosteroids in the long-term management of asthma.
