Abstract
An inhaled long-acting bronchodilator hascontributed to the treatment of COPD patients as powerfully as to have changed the disease concept of COPD from an irreversible disease to a treatable disease. Recently a new generation of inhaled long-acting bronchodilators are becoming available. Among them, a dual bronchodilator or a fixed combination of long-acting muscarinic antagonist and long-acting beta-agonist has shown at least 150% as effective as a single componentin terms of symptom improvement, health-related quality of life, lung function improvement, and exacerbation prevention. The dual bronchodilator is expected to contribute one step further to the treatment of COPD.
