Tiotropium/Olodaterol: A Review in COPD.

Tiotropium/olodaterol (Stiolto™ Respimat®, Spiolto™ Respimat®) is a fixed-dose combination of the long-acting antimuscarinic agent tiotropium bromide (hereafter referred to as tiotropium) and the long-acting β2-adrenoreceptor agonist olodaterol delivered via the Respimat® Soft Mist™ inhaler. It is indicated for the maintenance treatment of airflow obstruction in adults with COPD. Several randomized, phase III studies of 6-52 weeks' duration evaluated the efficacy of once-daily tiotropium/olodaterol in patients with GOLD stage 2-3 or 2-4 COPD. Tiotropium/olodaterol maintenance therapy improved lung function to a greater extent than the individual components or placebo and provided clinically meaningful improvements in health-related quality of life and dyspnoea in 12- and 52-week studies. Tiotropium/olodaterol consistently improved 24-h lung function in 6-week studies, providing greater benefits than the monotherapies, placebo or twice-daily fixed-dose fluticasone propionate/salmeterol. Inspiratory capacity and exercise endurance were also improved with tiotropium/olodaterol following 6 or 12 weeks' treatment. The tolerability profile of tiotropium/olodaterol in the phase III studies was generally similar to that of the component monotherapies. The most common adverse events and serious adverse events during 52 weeks' therapy were respiratory in nature, with COPD exacerbation, unsurprisingly, reported most frequently with tiotropium/olodaterol and component monotherapies. Although additional data assessing the effect of tiotropium/olodaterol on exacerbations and comparative studies with other recommended therapies are needed to definitively position tiotropium/olodaterol, current evidence indicates that tiotropium/olodaterol is a useful treatment option for patients with COPD.
