Simple coaching may boost inhaler use in rare lung disease

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.
