A drug commonly used for the treatment of chronic obstructive pulmonary disease (COPD) successfully treats adults whose asthma is not well-controlled on low doses of inhaled corticosteroids, reported researchers supported by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health.
"This study's results show that tiotropium bromide might provide an alternative to other asthma treatments, expanding options available to patients for controlling their asthma," said NHLBI Acting Director Susan B. Shurin, M.D. "The goal in managing asthma is to prevent symptoms so patients can pursue activities to the fullest."
According to the study, adding tiotropium bromide to low doses of inhaled corticosteroids is more effective at controlling asthma than doubling inhaled corticosteroids alone, and as effective as adding the long-acting beta agonist salmeterol. The results were published online today in the New England Journal of Medicine and presented at the Annual Congress of the European Respiratory Society in Barcelona, Spain.
Increasing inhaled corticosteroids or supplementing them with long-acting beta agonists like salmeterol are the two preferred treatment options available for adults whose asthma is poorly controlled on low doses of inhaled corticosteroids. However, higher doses of corticosteroids do not improve symptoms for all patients and can have significant side effects, while long-acting beta agonists have come under scrutiny for their risk of worsening asthma symptoms that could result in hospitalization and, rarely, death.
"Tiotropium relaxes smooth muscle in the airways through a different mechanism than beta agonists, and thus may help people who do not respond well to currently recommended treatments," said study lead Stephen Peters, M.D., Ph.D., of Wake Forest University Baptist Medical Center, Winston-Salem, N.C. "Further analysis of the study data will help us better un
