Which of the following treatments is often used for allergic asthma alongside bronchodilators?

1. Long-acting beta agonists (LABA)

2. Inhaled corticosteroids (ICS)

3. Short-acting beta agonists (SABA)

4. Antimuscarinics

The correct answer is: Inhaled corticosteroids (ICS)

In the management of allergic asthma, inhaled corticosteroids (ICS) play a crucial role alongside bronchodilators. ICS are anti-inflammatory medications that help to reduce airway inflammation, which is a key component of asthma. By addressing the underlying inflammation, these medications improve airway function and decrease the frequency and severity of asthma attacks. Using ICS in conjunction with bronchodilators helps ensure a comprehensive approach to asthma treatment. While bronchodilators, such as short-acting beta agonists (SABAs) and long-acting beta agonists (LABAs), provide quick relief by relaxing the muscles around the airways, they do not address the inflammation that characterizes allergic asthma. Therefore, the combination of ICS and bronchodilators offers both immediate symptom relief and ongoing management of inflammation. Other treatment options like antimuscarinics may have some application in asthma management, particularly in specific cases or when other options are not suitable, but they are not the primary choice for allergic asthma management. The focus on reducing inflammation with ICS distinguishes this treatment as a cornerstone in managing the condition effectively.
