NCT00981851

Brief Summary

The final purpose of this study is to determine whether bronchodilation and cigarette smoking in Chronic Obstructive Pulmonary Disease (COPD) patients interact, resulting in an increase of cardiovascular disease. The aim of this part of the study is to demonstrate the basic mechanism: Does increased respiratory function after administration of a bronchodilator in patients with COPD lead to elevated pulmonary retention of the harmful compounds in inhaled cigarette smoke and to short-term biological effects associated with cardiovascular disease?

Outcome Measures

Primary Outcomes (1)

  • cigarette smoke retention

    retention measurement is during smoking. smoking is 1 cigarette before and 1 cigarette 45 minutes after medication inhalation for each arm. 1 week between arms

Secondary Outcomes (4)

  • (hs)CRP

    3 times within 2 hours for each arm

  • fibrinogen

    3 times within 2 hours for each arm

  • respiratory function

    at baseline and repeatedly around medication inhalation for 1.5 hours

  • smoking pattern: smoke inhalation and smoke exhalation time and volume

    during smoking cigarettes: twice for each arm.

Study Arms (2)

beta 2 agonist + anticholinergic aerosol

ACTIVE COMPARATOR
Drug: Tiotropium (Spiriva) + Salbutamol (Ventolin)

placebo inhalation

PLACEBO COMPARATOR
Drug: placebo

Interventions

1 time inhalation of 5 mcg of Tiotropium bromide by Respimat and 400 mcg of Salbutamol by Volume Spacer. cigarette smoking

Also known as: Spiriva Respimat, Ventolin Aerosol
beta 2 agonist + anticholinergic aerosol

1 time inhalation of placebo with the amount of puffs similar to the active comparator. cigarette smoking

Also known as: Ventolin placebo and Spiriva placebo
placebo inhalation
