How Macitentan works in the bodyMacitentan helps treat pulmonary arterial hypertension (PAH) by blocking signals coming from endothelin-1 and -2, which are molecules released by the vascular endothelium. It does this by binding to two receptors in the body, E<sub>A</sub> and E<sub>B</sub>. When endothelin molecules bind to the E<sub>A</sub> receptor, it causes the cells to release calcium, which makes the cells contract and narrow the blood vessels. This leads to PAH. When endothelin binds to the E<sub>B</sub> receptor, it
