About this study

Official title: Effect of Methacholine, Long-acting M-cholinolytic and beta2-agonist on the Binding Activity of Beta-receptors in Healthy Volunteers

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.

Read the detailed description

Long-acting beta2-agonists and anticholinergics are main drugs in therapy of chronic obstructive pulmonary disease . Beta-agonists exert their bronchodilatory effects via β2 adrenoceptors located on airway smooth muscle cells. Anticholinergics block mainly M3-cholinoreceptors located in the airways, thus inhibiting bronchoconstriction. Metacholine blocks M2-cholinoreceptors thus inducing bronchoconstriction. It is known, that muscarine and beta-receptors interact with each other, but the detailed mechanism is unknown. For evaluating the binding activity of beta-receptors after inhalation of these drugs the modified radioligand method was used.

    Measured: Baseline (pre-dose), 60 minutes

  2. 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.

    Measured: Baseline (pre-dose), 40 minutes

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

    Difference of change of beta-receptor binding activity measured with modified radioligand method before and after inhalation of metacholine

    Measured: Baseline (pre-dose), 40 minutes

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

    Difference of change of beta-receptor binding activity measured with modified radioligand method before and after inhalation of metacholine

    Measured: Baseline (pre-dose), 40 minutes
