NCT04137029

Brief Summary

Interventional open-labeled study in parallel groups is aimed to evaluate changes of beta receptors in healthy volunteers under the influence of inhaled metacholine, long-acting anticholinergics and beta-agonists using modified radioligand method.

Outcome Measures

Primary Outcomes (2)

  • Change from baseline beta-receptor binding activity at 60 min after the inhalation of formoterol or tiotropium.

    Beta-receptor binding activity will be measured with modified radioligand method before and after 60 min after the inhalation of formoterol or tiotropium

    Baseline (pre-dose), 60 minutes

  • Change from baseline beta-receptor binding activity at 40 min after the challenge test with metacholine.

    Beta-receptor binding activity will be measured with modified radioligand method before and after 40 min after the challenge test with metacholine.

    Baseline (pre-dose), 40 minutes

Secondary Outcomes (4)

  • Comparison of beta-receptor binding activity measured with modified radioligand after formoterol and tiotropium.

    Baseline (pre-dose), 60 minutes

  • Comparison of beta-receptor binding activity measured with modified radioligand method after formoterol or tiotropium in smokers and non-smokers.

    Baseline (pre-dose), 60 minutes

  • Comparison of beta-receptor binding activity measured with modified radioligand after metacholine

    Baseline (pre-dose), 40 minutes

  • Comparison of beta-receptor binding activity measured with modified radioligand method after inhalation of metacholine in smokers and non-smokers.

    Baseline (pre-dose), 40 minutes
