Breathe Easier with Two Bronchodilators
Background: About 90% of patients with COPD are still short of breath with activities if using a single long-acting bronchodilator (either a beta-agonist or a muscarinic antagonist). In such situations, the 2017 GOLD statement recommends use of a combination of both classes of bronchodilators to achieve the best effects (see my post under the heading COPD News on December 3, 2016). Thus, the experts on the GOLD committee agree that you should be able to breathe easier with two bronchodilators.
Study: Dr. Edward Kerwin and co-authors who work at GlaxoSmithKline pharmaceutical company studied a total of 494 patients with COPD who reported that they experienced at least some shortness of breath despite taking a long-acting bronchodilator tiotropium (brand name: Spiriva) in the HandiHaler device for at least three months. Patients were assigned by chance to either continue Spiriva HandiHaler OR to use a combination of
two bronchodilators (brand name: Anoro Ellipta). The study results were published in the International Journal of COPD, 2017, volume 12, pages 745-755.
Results: Compared with a single bronchodilator (brand name, Spiriva HandiHaler), there were significantly greater improvements in breathing tests (lung function), the need to use albuterol as a rescue inhaler, and in shortness of breathe with activities of daily living. There were no differences is side effects between treatments.
Conclusions: Two different classes of bronchodilators provide greater benefits, including being able to breathe easier, than one bronchodilator.
My Comments: The results of this study are consistent with several other trials showing quite simply that “two is better than one” in most things in life including inhaled bronchodilators.
At the present time there are three available “two in one” bronchodilator inhalers – brand names are Anoro, Stiolto, and Bevespi. A fourth one called Utibron should become available in the near future.
If you are taking a single inhaled bronchodilator and have shortness of breath, I suggest that you ask your health care professional whether a trial of a “combination bronchodilator” is reasonable. At least one of these options should be covered by most health insurance policies.
