Which drug requires regular administration due to its anti-inflammatory mechanism for the treatment of asthma?

Mometasone is correct because it is a corticosteroid that works by reducing inflammation in the airways, making it effective in the long-term management of asthma. Regular administration of mometasone helps to control the underlying inflammation associated with asthma, which is critical for maintaining optimal respiratory function and preventing asthma exacerbations. Unlike bronchodilators, which are often used on an as-needed basis, corticosteroids like mometasone require consistent daily use to ensure that inflammation is effectively managed over time.

In contrast, tiotropium is a long-acting anticholinergic that is typically used for chronic obstructive pulmonary disease (COPD) management rather than primarily for asthma. Salmeterol is a long-acting beta-agonist (LABA) that provides prolonged bronchodilation but does not have inherent anti-inflammatory properties and is usually used in combination with corticosteroids for better asthma control. Albuterol is a short-acting beta-agonist (SABA) used for quick relief of asthma symptoms but is not meant for regular maintenance treatment. Thus, mometasone is the drug that specifically addresses the need for ongoing anti-inflammatory action in asthma management.
