Prostacyclin (PGI(2)) and its analogs are useful for the treatment of various vascular disorders, but their half-lives are too short for widespread clinical application. To overcome this drawback, we have synthesized a novel diphenylpyrazine derivative, 2-[4-[(5,6-diphenylpyrazin-2-yl)(isopropyl)amino]butoxy]-N-(methylsulfonyl)acetamide (NS-304), a prodrug(More)
PURPOSE Targeting the prostacyclin pathway is an effective treatment option for pulmonary arterial hypertension (PAH). Patients with PAH have a deficiency of prostacyclin and prostacyclin synthase. Selexipag is an orally available and selective prostacyclin receptor (IP receptor) agonist. Selexipag is hydrolyzed to its active metabolite ACT-333679, also a(More)
PURPOSE Selexipag is a new orally available nonprostanoid prostacyclin receptor agonist for the treatment of pulmonary arterial hypertension. Warfarin is commonly used in patients with pulmonary arterial hypertension. Possible pharmacodynamic and pharmacokinetic interactions between selexipag and warfarin in healthy individuals were investigated. METHODS(More)
