Brief Summary

The purpose of this study was to investigate the acute effects of sildenafil on diffusion capacity, a commonly performed pulmonary function test, which is used to assess the lungs' gas exchange capability. This study does not assess safety or efficacy of the drug. The study does not have clinical end points. The variables studied are diffusion capacity and 6 minute walk after a single dose of sildenafil. This study has been completed.

Conditions

Diffuse Parenchymal Lung Disease; Pulmonary Hypertension

Keywords

Pulmonary hypertension; Parenchymal Lung Disease; Diffusion Capacity

Outcome Measures

Primary Outcomes (1)

• Change in Diffusion Capacity Measured at Baseline and One Hour.

  Determine the acute effect of oral sildenafil on diffusion capacity in patients with diffuse parenchymal lung disease and concomitant pulmonary hypertension

  Baseline and one hour

Secondary Outcomes (1)

• Change in 6 Minute Walk Distance

  Baseline and one hour

Study Arms (1)
