|
Adrenergic bronchodilators
|
(specifically beta2-adrenoreceptor agonists) are inhaled medicines that help open up the air passages. They are used to treat asthma and chronic bronchitis. They dilate the bronchi by a direct action on the beta2-adrenoreceptors on the bronchial smooth muscle and relax the muscle.
|
|
The three types of prescription bronchodilating drugs are
|
β2-agonists (short- and long-acting)
anticholinergics (short-acting) theophylline (long-acting) |
|
Anticholinergic bronchodilators
|
(or muscarinic receptor antagonists) block the parasympathetic nerve reflexes that cause the airways to constrict, so allow the air passages to remain open. Muscarinic receptor antagonists bind to muscarinic receptors and inhibit acetylcholine mediated bronchospasm.
Anticholinergic bronchodilators are used more to treat chronic obstructive pulmonary disease than to treat asthma. |
|
Inhaled corticosteroids
|
act locally in the lungs to inhibit the inflammatory process, which causes asthma. They are potent anti-inflammatory agents and effectively reduce asthma symptoms. Corticosteroids prevent asthma attacks and improve lung function. Inhaled corticosteroids may also be used to treat chronic obstructive pulmonary disease that has an asthmatic component.
Inhaled corticosteroids deliver the medicine directly into the lungs so a smaller dose of corticosteroid is sufficient to control the symptoms. This minimizes the amount of corticosteroid that is absorbed systemically, so reduces the occurrence of side effects which one would normally experience while on long-term oral corticosteroid use. |
