The objective of pharmacological treatment of chronic obstructive pulmonary disease (COPD) is to prevent and control symptoms, reduce the frequency and severity of exacerbations, and improve general health status and exercise tolerance. None of the classes of drugs currently used in the treatment of COPD are able to modify the progressive decline in lung function which is the hallmark of this disease.

Bronchodilators are main form of treatment. There are four main classes of Bronchodilator; short acting bronchodilators, single long acting bronchodilators, dual bronchodilators, and combination ICS and LABA inhalers. In COPD Pharmacotherapy, these drugs are grouped into Single, Dual and Triple Therapy.
