Inhaled corticosteroids are medications commonly used in the treatment of asthma and chronic obstructive pulmonary disease (COPD). These medications work by reducing inflammation in the airways, which helps to decrease symptoms such as wheezing, coughing, and shortness of breath. Inhaled corticosteroids are considered a first-line treatment for these respiratory conditions, as they are effective at controlling symptoms and preventing exacerbations when used regularly. They are typically used in combination with other medications, such as bronchodilators, to provide comprehensive management of these chronic respiratory conditions. Overall, inhaled corticosteroids play a crucial role in improving the quality of life and reducing the risk of complications for individuals with asthma and COPD.
