Which of the following best describes inhaled corticosteroids?

Inhaled corticosteroids are a cornerstone in the management of asthma, primarily used for their ability to prevent inflammation in the airways. They work by reducing the production of inflammatory substances and by decreasing airway hyper-responsiveness, which helps to maintain better control of asthma symptoms over time.

Using inhaled corticosteroids daily aims to help manage the underlying inflammation that contributes to asthma severity and frequency of attacks. This preventive approach leads to a reduction in exacerbations and the need for rescue medications, ultimately improving overall lung function and quality of life for patients.

Immediate relief medications, often referred to as rescue inhalers, are distinct from inhaled corticosteroids. They are typically short-acting bronchodilators used during an asthma attack to alleviate acute symptoms quickly. Additionally, while inhaled corticosteroids are vital for those with chronic symptoms, they are not exclusively for this group; rather, they serve as a foundational treatment for many individuals with asthma, regardless of symptom frequency.
