What condition is primarily treated with long-acting beta-agonists (LABAs)?

• A. Asthma
• B. Chronic obstructive pulmonary disease (COPD)
• C. Allergic rhinitis
• D. Hypertension

Answer: (B)

Long-acting beta-agonists (LABAs) are primarily used in the management of chronic obstructive pulmonary disease (COPD) because they help in the relaxation of airway muscles, leading to improved airflow and relief from symptoms such as shortness of breath and wheezing. LABAs have a prolonged duration of action, which allows for less frequent dosing and better control of respiratory symptoms, making them particularly useful in COPD management where airway obstruction is a significant concern.

Asthma is also treated with LABAs, but they are typically used in conjunction with inhaled corticosteroids for long-term management rather than as a primary treatment. Allergic rhinitis is managed with antihistamines and decongestants, not with LABAs, while hypertension is treated with various antihypertensive agents that target different mechanisms in vascular regulation, not beta-agonists. Therefore, the primary application of LABAs lies in the context of COPD management.
