Drug Class Insights

Prostacycl in and analogs segment dominated the PAH market, holding a 47.11% revenue share in 2024, driven by their potent vasodilatory effects. Produced via the cyclooxygenase pathway in pulmonary endothelial cells, prostacyclins like epoprostenol and treprostinil activate G protein-coupled receptors, promoting smooth muscle relaxation and vasodilation. Selexipag, an oral prostacyclin receptor agonist, reduced morbidity/mortality in the GRIPHON trial (NCT01106014), with real-world data from the SPHERE registry (NCT03278002) confirming its efficacy in reducing hospitalizations. Ongoing trials, such as United Therapeutics’ Phase I study of a novel oral prostacyclin agonist (2025), underscore continued innovation.

Soluble guanylate cyclase (sGC) stimulators segment led by riociguat (Adempas), are the fastest-growing segment, projected to achieve a 5.5% CAGR through 2033. sGC, a nitric oxide receptor, addresses impaired NO-sGC-cGMP signaling in PAH, which causes endothelial dysfunction and vascular remodeling. Riociguat’s efficacy in improving 6-minute walk distance and hemodynamics was validated in the PATENT-1 trial (NCT00810693), with sustained benefits in real-world studies. Recent data from a 2024 ESC/ERS guideline update highlight sGC stimulators’ role in combination therapies, driving market growth.

Type Insights

The branded segment dominated the PAH market in 2024, capturing a revenue share of 87.99%, driven by robust R&D investments and recent approvals such as Merck’s Winrevair (sotatercept), an activin signaling inhibitor approved in March 2024 (FDA, 2024). Strong clinical efficacy, as seen in Winrevair’s STELLAR trial, which improved bolsters branded drug demand. Partnerships, such as Chiesi Group and Gossamer Bio’s May 2024 collaboration for seralutinib, further strengthen pipelines. Orphan drug designations and extended patents (e.g., Adempas until 2034) sustain branded dominance, though patent expiries like Uptravi’s in 2025 challenge future growth.

The generics segment is projected to grow at the fastest CAGR of 6.6% over the forecast period, fueled by patent expiries and cost-effective alternatives. For instance, Granules’ generic Revatio (sildenafil) received FDA approval in December 2023, enhancing affordability. Expiries of key drugs such as Orenitram (2025) and Adcirca (2027) enable generic penetration, particularly in cost-sensitive markets such as Asia-Pacific. Companies such as Lupin and Dr. Reddy’s are expanding generic offerings, with Dr. Reddy’s launching generic treprostinil in April 2023. This trend, supported by increasing healthcare access, drives generics’ rapid growth, reshaping market dynamics by 2033.

Route of Administration Insights

The oral segment dominated the PAH market with a revenue share of 55.59% in 2024, driven by patient preference for non-invasive, convenient administration and the expanding portfolio of oral therapies. Drugs such as Letairis, Opsumit, Adcirca, and Uptravi improve adherence, crucial for managing chronic PAH. The FDA’s approval of OPSYNVI (macitentan and tadalafil) in March 2024, the first once-daily oral combination therapy, significantly boosted the segment by simplifying treatment regimens and enhancing efficacy. Increasing R&D investments in oral formulations, such as United Therapeutics’ Phase I trial for a novel oral prostacyclin agonist (2025), further solidify the segment’s lead.

Inhaled and injectable routes, while effective, trail due to complexity and invasiveness, making oral therapies the preferred choice. The oral segment’s growth is fueled by innovations addressing severe PAH cases, with drugs like selexipag reducing hospitalization rates in real-world SPHERE registry data (JHLT, 2024). Patent expiries, such as Uptravi’s in 2025, may shift some demand to generics, but branded oral drugs maintain dominance through superior efficacy and physician trust. Collaborations, such as Chiesi Group’s with Gossamer Bio (May 2024), support pipeline development, ensuring the oral segment’s sustained expansion in cost-sensitive markets like Asia-Pacific.
