Olodaterol shows a potent, nearly full agonistic response at the hβ2-adrenoceptor (EC50=0.1 nM; intrinsic activity=88% compared with isoprenaline) and a significant selectivity profile (241- and 2299-fold against the hβ1- and hβ3-ARs, respectively). Likewise, olodaterol is able to potently reverse contraction induced by different stimuli in isolated human bronchi[2].

Olodaterol is a long acting β2-agonist that induces bronchodilation up to 24 h after dosing in patients with chronic obstructive pulmonary disease (COPD) . Olodaterol dose-dependently attenuates cell influx and pro-inflammatory mediator release in murine and guinea pig models of pulmonary inflammation. Olodaterol attenuates pro-inflammatory mediator release from human parenchymal explants and whole blood and reduced expression of CD11b adhesion molecules on granulocytes, but without direct effects on IL-8-induced neutrophil transwell migration[3]. Once-daily olodaterol 5 μg is an effective therapy in improving lung function and symptomatic outcomes in patients with moderate to very severe (COPD) receiving other maintenance therapy, with a satisfactory safety profile[4].
