The Evolving Landscape of Pulmonary Hypertension Treatment: From Vasodilation to Disease Modification, Clinical and Translational Science, July 31, 2026
For 30 years, pulmonary arterial hypertension (World Health Organisation, WHO, Group 1 pulmonary hypertension) treatment relied on three vasodilator-based pathways: endothelin receptor antagonists (bosentan, ambrisentan, macitentan), the nitric oxide/cGMP pathway (sildenafil, tadalafil, riociguat), and prostacyclin pathway agents (treprostinil, epoprostenol, selexipag, etc.).
