Effect of Losartan on Chronic Obstructive Pulmonary Disease (COPD)
This study is currently recruiting participants.
Verified by National Heart, Lung, and Blood Institute (NHLBI), July 2008
First Received: July 18, 2008   No Changes Posted
Sponsor: National Heart, Lung, and Blood Institute (NHLBI)
Information provided by: National Heart, Lung, and Blood Institute (NHLBI)
ClinicalTrials.gov Identifier: NCT00720044
  Purpose

Losartan, an angiotensin receptor blocker, has been effective in preventing the development of emphysema and lung inflammation in animal models of COPD. Moreover, there is epidemiologic evidence that suggests that this drug may be effective in reducing COPD morbidity and mortality.

This study will provide treatment with either losartan or placebo for a period of 12 months to determine whether there is progression of COPD as measured by high-resolution CT scans, lung function, or blood tests for inflammation.
