Adempas (riociguat) is a soluble guanylate cyclase stimulator prescribed to treat high blood pressure in the lungs, pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) in adults. This medication works by stimulating the nitric oxide-soluble guanylate cyclase pathway to relax and widen pulmonary blood vessels, reducing pressure in the lungs and improving exercise capacity. For patients seeking affordable specialized medications, working with qualified healthcare providers ensures proper diagnosis, appropriate monitoring, and access to authentic treatments with proper safety oversight for managing these rare but serious pulmonary vascular conditions effectively.
