Helping patients take their inhaled lung pressure medication correctly

This trial is testing whether working with a pharmacist can help patients with pulmonary arterial hypertension (a rare lung condition affecting blood pressure in the lungs) take their medication — iloprost, an inhaled treatment — more consistently and effectively. The study compares two groups: one that receives pharmacist support and guidance on using the inhaler correctly, and one that receives standard care. The goal is to see if this extra support improves how well patients stick to their treatment and reduces bothersome side effects.

Iloprost is an important medication for this condition, but patients often struggle with it because it requires frequent doses throughout the day and has a specific technique needed to use the inhaler properly. While pharmacist support has been proven helpful in other lung diseases like asthma, it hasn't been well studied in pulmonary arterial hypertension — so this trial aims to fill that gap.
