There are several different forms of medication that can be used for the treatment of asthma, including bronchodilators, inhaled corticosteroids, or a combinaton of the two.
Short-acting bronchodilator drugs are taken by inhaling. They relax the airways and relieve symptoms of wheezing and breathlessness.
Inhaled corticosteroids are given to control inflammation of the airways, usually as regular daily treatment.
In more severe cases of asthma, longer acting bronchodilators, in combination
with corticosteroids, can give more effective control.
