Purpose
The purpose of this multi-center international trial is to evaluate the safety and effectiveness of adding iloprost or placebo (an inactive substance that contains no active study drug) to sildenafil therapy for pulmonary arterial hypertension (PAH). The study will also examine whether patients on sildenafil can reduce the number of iloprost inhalations from the approved 6 doses per day to 4 doses per day.

Primary Outcome Measures:
- Number of Participants With Change From Baseline to Week 16 in 6-Minute Walk Test (MWT) in Double-blind, Modified Intent To Treat (MITT) Population [ Time Frame: Day 1 to Week 16 ]Comparing number of Modified Intent to Treat population in double-blind who improved in the 6-minute walk distance - from baseline distance between 100-450 meters. Any increase in walk distance was considered improvement from baseline. The 6-minute walks were measured in meters using a test administrator, a stop watch, and markers to identify the course.
Secondary Outcome Measures:
- Assess the Efficacy of the Addition of Inhaled Iloprost in Patients With PAH Receiving a Stable Dose of Oral Sildenafil [ Time Frame: Baseline Week 16 up to 48 weeks ]The change in 6-minute walk distance (6-MWD) measured after inhalation, following 16 weeks of combination therapy with inhaled iloprost (administered 6 times or 4 times per day) inhaled iloprost plus sildenafil during the open-label extension phase.
