Riociguat Overview

  • Riociguat is used to treat pulmonary arterial hypertension (PAH; high blood pressure in the vessels that carry blood to the lungs). Riociguat is also used to treat chronic thromboembolic pulmonary hypertension (CTEPH; high blood pressure in the lung arteries caused by blood clots that narrow or block blood flow) in adults who cannot have surgery or for those treated with surgery who continue to have high lung blood pressure levels after surgery. Riociguat may improve the ability to exercise in people with PAH and CTEPH and may slow the worsening of symptoms in people with PAH. Riociguat is in a class of medications called soluble guanylate cyclase (sGC) stimulators. It works by relaxing the blood vessels in the lungs to allow blood to flow easily.
