The Role of Tiotropium+Olodaterol Dual Bronchodilator Therapy in the Management of Chronic Obstructive Pulmonary Disease / 결핵및호흡기질환

ABSTRACT

Bronchodilator therapy is central to the management of chronic obstructive pulmonary disease and are recommended as the preferred treatment by the Global Obstructive Lung Disease Initiative (GOLD). Long acting anti-muscarinics (LAMA) and long acting β₂ agonists (LABA) are both more effective than regular short-acting drugs but many patients remain symptomatic despite monotherapy with these drugs. Combination therapy with LAMA and LABA increases the therapeutic benefit while minimizing dose-dependent side effects of long-acting bronchodilator therapy. The TOviTO programme has investigated the benefits of treatment with a combination of tiotropium and olodaterol administered via a single inhaler. Tiotropium+olodaterol 5/5 µg significantly improved forced expiratory volume in 1 second (FEV₁) area under the curve from 0 to 3 hours, trough FEV₁ health status and breathlessness versus the mono-components and placebo. Tiotropium+olodaterol 5/5 µg also increased endurance time and reduced dynamic hyperinflation during constant work rate cycle ergometry. On the basis of these and other studies the 2017 GOLD report recommends escalating to dual bronchodilator therapy in patients in groups B and C if they remain symptomatic or continue to have exacerbations and as initial therapy for patients in group D.
