Summary

This study tests whether extra guidance from a pharmacist can help people with pulmonary arterial hypertension (PAH) use their inhaled iloprost correctly and consistently. PAH is a rare, serious lung condition that makes it hard to breathe. The trial will enroll 72 adults who already take inhaled iloprost. Half will get standard care, and half will also receive personalized coaching on inhaler technique and sticking to their medication schedule. The goal is to see if this support improves adherence and reduces side effects.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
iloprost (inhaled)
What this could lead to
If successful, this could show that simple pharmacist support helps PAH patients use their inhaler correctly and stay on treatment, potentially improving their quality of life.
What could go wrong
This is a small, early-stage study (72 people) testing a behavioral intervention, not a new drug. Results may not apply to all PAH patients, and adherence improvements may not translate to better health outcomes.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 72 people

The number the study aims to enrol. It can still change while the study runs.

Started
