A brief description of the mechanisms of action of various bronchodilators (including salbutamol and salmeterol) for use in asthma and COPD. Asthma is a condition involving recurrent, reversible obstruction of the airways in response to stimuli that are not themselves noxious, and which do not affect non-asthmatic subjects. The most common form of this, is the allergy to the faeces produced by house dust mites (HDM). This causes patients to produce histamine and leukotrienes, which cause the airways to constrict (bronchoconstriction).
