Asthma & COPD Inhalers
Inhaled corticosteroids, long-acting bronchodilators, combination inhalers, and biologic add-on therapies for asthma and chronic obstructive pulmonary disease.
How Asthma & COPD Inhalers Work
Inhaled corticosteroids (ICS) reduce airway inflammation. Long-acting beta-agonists (LABA) relax airway muscles for 12-24 hours. Long-acting muscarinic antagonists (LAMA) block bronchoconstriction. Triple combination inhalers (Trelegy) combine ICS + LABA + LAMA. Biologics (Nucala, Xolair, Dupixent) target specific immune pathways in severe asthma that doesn't respond to inhalers alone.
