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. These medications help prevent asthma attacks and improve overall lung function. Regular use can lead to better control of symptoms and a reduced need for rescue medications. It's important for patients to follow their healthcare provider's instructions when using inhaled corticosteroids for optimal results.
