What is Opsumit used for?

Opsumit (Macitentan) is used to treat pulmonary arterial hypertension (high blood pressure in your lungs). Opsumit works by blocking endothelin, a substance that causes the blood vessels in your lungs to narrow, which restricts blood flow and puts strain on the heart. By blocking excessive production of endothelin, Opsumit helps open these blood vessels and improve pulmonary function. Take Opsumit as prescribed by your doctor. The typical dose is 10 mg once a day. You can take Opsumit with or without food. Swallow the Opsumit tablet whole and do not crush, chew, or break the tablet. While using Opsumit, you may need frequent blood tests.
