Final answer:
ICS (inhaled corticosteroids) are first-line controller therapy for asthma, while LABA (long-acting beta2-agonists) are add-on therapy. They both help manage and improve symptoms of asthma.
Step-by-step explanation:
ICS (inhaled corticosteroids) are commonly used as first-line controller therapy for asthma in primary care settings. They work by reducing airway inflammation and improving lung function. Examples of ICS include fluticasone, budesonide, and beclomethasone.
LABA (long-acting beta2-agonists) are often used as add-on therapy to ICS in the management of asthma. They help relax the muscles around the airways, making it easier to breathe. Examples of LABA include salmeterol and formoterol.
