Evidence in animals shows that losartan can prevent or reverse inflammation and lung damage due to smoking. The goal of this study is to determine whether this drug which is also used to treat hypertension can stabilize or improve lung function in people who have from chronic obstructive pulmonary disease (COPD).

Primary Outcome Measures:
  • Extent of emphysema on CT scan [ Time Frame: Measured at Month 12 ]

Secondary Outcome Measures:
  • Pulmonary function testing [ Time Frame: Measured at Month 12 ]

Estimated Enrollment: 120
Study Start Date: July 2008
Estimated Study Completion Date: August 2013
Estimated Primary Completion Date: August 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
Losartan 100 mg daily
Drug: Losartan
Losartan 100 mg daily
Other Name: Cozaar
Placebo Comparator: 2
Placebo 1 pill daily
Drug: Placebo
Placebo pill daily
Other Name: "Sugar pill"

Detailed Description:
Participants will be given either losartan in a dose of 50-100 mg per day for a period of one year. During that time, they will have lung function tests, breathing tests, and computed tomograms of the chest. These tests will determine whether there is inflammation in the lung and whether there is progressive involvement of the lung with COPD.
