1) Airway tube spasm/closing (bronchospasm) that is variable and reversible:

                                                                           Airway tube open             Airway tube spasm

2) Inflammation (swelling/congestion) of those airway tubes:

Normal                                    Inflamed


1) Reliever medication (bronchodilator)(blue):
   - Names: Ventolin, salbutamol, Airomir, Bricanyl

3) Controller medication:  Inhaled steroid

   - Decreases airway inflammation
   - Needs time to gradually decrease inflammation therefore...
       ... needs to be taken REGULARLY (every day) to work effectively
   - Prevents further symptoms from occurring

4) Combined inhaled steroid + Long acting bronchodilator:
   - Brand names: Symbicort (red), Advair (purple)
