Understanding How Inhalers Relieve Bronchial Muscle Constriction

Inhalers deliver medication directly to the lungs to treat asthma/COPD. During an attack, bronchial muscles constrict, narrowing airways and causing wheezing, coughing, chest tightness, shortness of breath.

Two Main Types

• Bronchodilators: Relax bronchial muscles → immediate relief for acute attacks.
• Corticosteroids: Reduce airway inflammation → prevent attacks.

Inhalers are effective, convenient, portable delivery for rapid symptom relief.
