What type of medications are used on a daily basis to prevent asthma exacerbations?

Controller medications are specifically designed to be used on a daily basis to prevent asthma exacerbations and to manage chronic asthma symptoms. These medications work by reducing inflammation in the lungs, improving airflow, and minimizing the frequency and severity of asthma attacks. Common types of controller medications include inhaled corticosteroids, long-acting beta-agonists, and leukotriene modifiers, among others.

In contrast, rescue medications are intended for immediate relief during an asthma attack and are not meant for daily use. Antibiotics are not typically used in asthma treatment unless there is a co-occurring bacterial infection, and they do not prevent exacerbations. Oral antihistamines are generally used for allergic reactions and may not have a direct role in managing asthma symptoms, particularly in preventing exacerbations. Therefore, controller medications are the appropriate choice for daily preventative asthma management.
