Primary Outcome Measures:
  • Respiratory function test [ Time Frame: two o'clock ]
    Evaluation of pulmonary mechanics before and after salbutamol (short-acting bronchodilator) in healthy individuals, smokers and chronic obstructive pulmonary disease in stages: mild, moderate, severe and very severe according to GOLD criteria.


Secondary Outcome Measures:
  • Salbutamol [ Time Frame: twenty minutes ]
    In the bronchodilator test will be used 400 micrograms of beta2-agonist short-acting. They will be asked to exhale slowly until they can no longer expel more air from the lungs. To place the inhaler with a spacer between the lips, pressing them well, but no bite. Shortly thereafter start to breathe through the mouth and will be released a jet of 100 micrograms of the bronchodilator. Then they will hold their breath for 10 seconds. 3 puffs are made with 1 minute interval between each application.


Estimated Enrollment: 200
Study Start Date: June 2011
Estimated Study Completion Date: September 2012
Estimated Primary Completion Date: January 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Salbutamol
Short-acting bronchodilator for use in humans released by the Ministry of Health, widely used worldwide for the treatment of chronic obstructive pulmonary disease.
Drug: Salbutamol sulphate
bronchodilator test, beta2-agonist, short-acting, six hours duration, 400 micrograms.
Other Names:
  • Aerogold
  • GO/DRUGS/341/L
  • LOTE: YR1070

Detailed Description:
Clinical evaluation will be conducted and anthropometric measurements, then the pulmonary function tests: forced oscillation technique (FOT), whole body plethysmography, spirometry and-administration of salbutamol aerosol for assessment of bronchodilator response. After 20 minutes, the individual will be evaluated again following the same sequence.
