Question 1

Anti-inflammatory agents:

Answer 1

Inhaled corticosteroids, leukotriene modifiers, and mast cell stabilizers help prevent inflammatory cells, suppressing release of inflammatory mediators, and reversing capillary permeability, in turn reducing airway edema

Question 2

Mucolytic agents:

Answer 2

Decrease the viscosity of mucus secretions by altering their composition and consistency making them easier to expectorate

Question 3

Expectorant agents:

Answer 3

Increase the respiratory secretions which help loosen mucus

Question 4

Bronchodilator agents:

Answer 4

Relieve bronchi spasm by stimulating the receptors that cause bronchial smooth muscle relaxation or by blocking the receptors that trigger bronchi constriction
