Inhaled corticosteroids are medications commonly used to manage respiratory conditions like asthma and chronic obstructive pulmonary disease (COPD). They work by reducing inflammation in the airways, making it easier to breathe. These medications are delivered directly to the lungs through an inhaler or nebulizer, allowing for targeted treatment with fewer side effects compared to oral corticosteroids. Patients using inhaled corticosteroids may experience improved lung function and reduced symptoms, such as wheezing and shortness of breath. It's important to use these medications regularly as prescribed, even when feeling well, to maintain control over respiratory conditions and prevent flare-ups.
