Brief Summary:
Patients with symptomatic idiopathic pulmonary arterial hypertension (IPAH), or familial pulmonary arterial hypertension (FPAH) or pulmonary hypertension associated with Human immunodeficiency virus (HIV) or drugs/toxins in New York Heart Association (NYHA) functional class II to IV at baseline, naive to PAH treatment or currently being treated with a stable dose of either bosentan, ambrisentan or sildenafil will be enrolled in the PROWESS 15 study. This randomized, double blind, placebo-controlled, crossover, and single-dose study will determine whether a single inhaled dose of iloprost using the power 15 disc improves exercise capacity compared to placebo in patients with pulmonary arterial hypertension (PAH).

Primary Outcome Measures :
- 6-minute-walk Distance (6MWD) [ Time Frame: Study day 2 or study day 3 ]
The 6-minute walk test was performed 20-40 minutes after treatment. This was a non-encouraged test (the person conducting the test did not encourage the patient to walk farther or faster) that measured the distance covered over a 6-minute walk.
It was conducted by a trained member of the site staff who was listed on the site's delegation of authority sheet. For patients who had never performed a 6-minute walk test previously, a training test was requested before the qualifying tests for randomization.
Secondary Outcome Measures :
- Borg Dyspnea Score [ Time Frame: Study day 2 or study day 3 ]The Borg scale is a category-ratio scale, commonly used to evaluate the effects of exercise on dyspnea. The original and modified scales have ratio properties ranging from 0 = nothing at all to 10 = very, very severe, with descriptors from 0 to 10. Descriptors have been modified by others so that 10 has been labeled "extremely severe," or "the worst possible dyspnea imaginable." Reliability and validity have been reported in a general population and in patients with PAH as well as other respiratory conditions.
