Brief Summary:
Cross-over trial of the effect of a salt particle inhaler on pulmonary muco-ciliary cleansing in COPD patients as measured by lung scintigraphy.

Condition or disease Intervention/treatment Phase
COPD Copd Bronchitis Device: Inhalation from a salt particle inhaler with or without content Not Applicable

Detailed Description:
Stable COPD patients will be examined twice with minimum two, maximum 14 days interval. In randomized order the patients will inhale from a salt particle inhaler with (active) or without (placebo) content.

Outcome Measures

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Muco-ciliary clearance [ Time Frame: Activity at time zero ]
    Retention of inhaled radioactive marker in percentage

  2. Muco-ciliary clearance [ Time Frame: Activity at time 30 minutes ]
    Retention of inhaled radioactive marker in percentage

  3. Muco-ciliary clearance [ Time Frame: Activity at time 90 minutes ]
    Retention of inhaled radioactive marker in percentage

  4. Muco-ciliary clearance [ Time Frame: Activity at time 120 minutes ]
    Retention of inhaled radioactive marker in percentage


Secondary Outcome Measures :
  1. Registering number of coughs [ Time Frame: Activity at any time between time zero and 120 minutes ]
    Number of coughs during investigation is noted

  2. Collection of sputum [ Time Frame: Activity at any time between time zero and 120 minutes ]
    Sputum during investigation is collected for analysis of radioactivity content

  3. Symptoms in the subjects health [ Time Frame: Activity at time zero ]
    Subjective symptom description during last 24 hours is done by a CCQ (Clinical COPD Questionnaire)

  4. Symptoms in the subjects health [ Time Frame: Activity at time 30 ]
    Subjective symptom description during investigation is done by a questionnaire

  5. Symptoms in the subjects health [ Time Frame: Activity at time 120 ]
    Subjective symptom description during investigation is done by a questionnaire
