Salmeterol is a drug used to prevent and relieve symptoms of wheezing, shortness of breath, and cough due to severe asthma or chronic obstructive pulmonary disease (COPD), including emphysema or chronic bronchitis.
Salmeterol belongs to the long acting beta agonist (LABA) bronchodilator group. This medicine works by widening the airways in the lungs, so that the airflow can flow more smoothly and the sufferer can breathe more easily.
Salmeterol can only be used to control and relieve complaints and symptoms, but cannot cure asthma and COPD . In the treatment of asthma, this drug can only be used as an adjunct if high-dose inhaled steroids cannot control complaints.
