End-User Dynamics And Use Case Pulmonary arterial hypertension (PAH) treatments are prescribed and administered across a limited but high-impact set of end users. Unlike broader therapeutic markets, PAH adoption is concentrated in specialized hospitals, academic centers, and referral clinics , with community hospitals and pharmacies playing supportive roles. The value chain here is tightly linked to specialist expertise and reimbursement approvals. Specialty Hospitals and PAH Centers These facilities dominate the market. They typically employ multidisciplinary teams — cardiologists, pulmonologists, and transplant specialists — who manage advanced PAH cases. Specialty centers are also the frontline for clinical trials, making them critical for early adoption of novel therapies. They often prescribe high-cost infused prostacyclin regimens and manage patients requiring invasive monitoring. General Hospitals and Clinics In many regions, initial diagnosis occurs in general hospitals before referral to specialized centers. These institutions handle first-line oral therapies , often PDE-5 inhibitors, which are more widely accessible. However, due to limited expertise, complex cases are usually escalated to tertiary care centers. Academic & Research Institutes Academic centers play a dual role: treating patients while also driving pipeline validation and biomarker research . These institutes are often involved in compassionate-use programs, providing early access to investigational therapies. Their role is growing as PAH research shifts toward genetic drivers and regenerative approaches . Retail & Specialty Pharmacies While not prescribers, specialty pharmacies are critical in distribution. They manage access to oral and inhaled therapies , coordinate insurance approvals, and provide adherence support programs. In North America, large specialty pharmacy chains work closely with manufacturers to streamline access for patients on combination therapy. Use Case Highlight A tertiary referral hospital in South Korea faced challenges managing adherence among young PAH patients on dual therapy. Many struggled with side effects and inconsistent medication use, leading to hospitalizations. The hospital piloted a program combining oral fixed-dose ERA + PDE-5 inhibitor therapy with a mobile adherence app linked to pharmacy refill data. Within a year, adherence improved by nearly 30%, hospitalization rates dropped, and patients reported a better quality of life. This example shows how blending drug innovation with digital health support can directly improve outcomes — and reduce costs for both hospitals and payers. Bottom Line Different end users are motivated by different factors: Specialty hospitals focus on complex care and trial participation. General hospitals emphasize accessible first-line treatments. Academic centers drive innovation and early adoption. Pharmacies enable continuity and affordability. The market is not about how many prescribers exist, but about how concentrated expertise and infrastructure determine access. That concentration makes end-user engagement strategies absolutely critical for drug developers.
