Airway constriction is a key issue in asthma, and medications that directly relax the airway smooth muscle are used to open the airways and relieve symptoms. These are bronchodilators. They work by relaxing the muscles around the airways, which widens the passages and improves airflow, providing quick relief during an asthma attack. Short-acting bronchodilators offer rapid relief, while longer-acting ones help with ongoing control.

Antibiotics target infections, not the airway narrowing seen in asthma. Antihistamines help with allergic symptoms but don’t address bronchoconstriction. Diuretics remove excess fluid and have no role in treating asthma.
