Mucus Secretion in the Airway Tract (N/A)

Mucus secretion in the airway tract is a complex physiological process crucial for maintaining respiratory health. It involves the production and secretion of mucins, primarily MUC5AC and MUC5B, by goblet cells, club cells, and submucosal glands. This secretion traps inhaled particles and pathogens, facilitating their removal via mucociliary clearance and cough. Dysregulation of mucus secretion, leading to hypersecretion or altered mucus properties, contributes to the pathophysiology of various respiratory diseases, including asthma, COPD, and cystic fibrosis. The expectorant effect encompasses mechanisms and agents that enhance mucus secretion or its clearance from the airways, often targeted therapeutically.

Expectorants: Increase airway hydration and mucus volume. Mucolytics: Break down mucus structure to reduce viscosity. Bronchodilators: Relax airway smooth muscle, facilitating mucus clearance. Corticosteroids: Reduce airway inflammation and mucus production. Macrolides: Reduce mucus hypersecretion and inflammation.
