Drug Class: beta-2 adrenergic agonist
General Properties:
Salmeterol xinafoate is a naphthoic acid.
A selective ADRENERGIC BETA-2 RECEPTOR agonist that functions as a BRONCHODILATOR when administered by inhalation. It is used to manage the symptoms of ASTHMA and CHRONIC OBSTRUCTIVE PULMONARY DISEASE.
Indication:
Salmeterol is indicated in the treatment of asthma with an inhaled corticosteroid, prevention of exercise induced bronchospasm, and the maintenance of airflow obstruction and prevention of exacerbations of chronic obstructive pulmonary disease. Salmeterol is used as a long-term (maintenance) treatment to prevent or decrease wheezing and trouble breathing caused by asthma or ongoing lung disease (chronic obstructive pulmonary disease-COPD, which includes chronic bronchitis and emphysema). It should only be used long-term if your asthma symptoms are not controlled by your other asthma medications (such as inhaled corticosteroids). Salmeterol must not be used alone to treat asthma. (See also Warning section.) It is also used to prevent asthma brought on by exercise (bronchospasm). Salmeterol works by relaxing the muscles around the airways so that they open up and you can breathe more easily. Controlling symptoms of breathing problems can decrease time lost from work or school.This medication does not work right away and should not be used for sudden attacks of breathing trouble. Your doctor must prescribe a quick-relief medicine/inhaler (such as albuterol) for sudden shortness of breath/asthma attacks while you are on this medication.
