Which of the following is a treatment option for asthma?

Inhaled corticosteroids are a cornerstone treatment for asthma management. They work by reducing inflammation in the airways, making it easier to breathe and helping to prevent asthma attacks. These medications are effective in controlling chronic asthma symptoms and are often used as a long-term treatment strategy to maintain control over the condition. They are usually administered through an inhaler, ensuring that the medication is delivered directly to the lungs where it is needed most.

Other treatment options mentioned do not directly address the underlying inflammation associated with asthma. Antibiotics are typically used to treat bacterial infections and would not be effective in treating asthma itself, which is primarily an inflammatory condition rather than an infection. Antihistamines are more commonly utilized to relieve allergy symptoms and may not provide the necessary control over asthma symptoms. Expectorants help to clear mucus from the airways, but they do not reduce inflammation or effectively manage asthma symptoms.

Thus, inhaled corticosteroids are recognized as a primary and effective treatment for individuals with asthma.
