Pulmonary arterial hypertension (PAH) is a rare, life-threatening disorder marked by considerable morbidity and mortality. A wide array of drugs are available to treat PAH. Phosphodiesterase 5 (PDE-5) inhibitors and endothelin receptor antagonists (ERAs) are the most commonly prescribed first-line treatments; the more-efficacious prostacyclin therapies are used in later lines. Branded therapies dominate the PAH treatment algorithm, and combination therapy is common.


  • What patient shares do key therapies and brands garner by line of therapy in newly diagnosed PAH patients? What are the quarterly trends in prescribing among recently treated and newly diagnosed PAH patients?
  • How have Uptravi, Orenitram, Remodulin, and Adempas been integrated into the treatment algorithm, and what are their sources of business?
  • What percentage of PAH patients receive drug therapy within two years of diagnosis and how quickly? What percentage of patients progress to later lines of therapy within two years of diagnosis?
  • What percentage of PAH patients are treated with monotherapy versus combination therapy? What are the most commonly used combinations?
  • What are the product-level compliance and persistency rates among drug-treated patients?


  • Adcirca, Tracleer, Letairis, Opsumit, Tyvaso, Ventavis, Orenitram, Uptravi, Remodulin, Adempas, sildenafil, epoprostenol
