Salmeterol is used for the treatment of asthma, chronic pulmonary obstructions, to prevent asthma attacks triggered by physical activity and, more generally, in the prevention of bronchospasm.


What is Salmeterol?


Salmeterol is an agonist of the beta-2 adrenergic receptors. By binding to these molecules, which are present in the smooth muscles associated with the respiratory tract, it stimulates relaxation. The net effect is bronchodilation.


How should Salmeterol be taken?


Salmeterol is taken in the form of powder by inhaling it through the mouth using suitable inhalers. Depending on the problem the posology can consist of two daily doses or a single administration from 30 minutes to one hour before physical activity.
