What is Macitentan

Macitentan was approved in October 2013. It is indicated for patients with pulmonary arterial hypertension, and is marketed under the brand name Opsumit. Macitentan is an antagonist/blocker of endothelin receptors on blood vessels and smooth muscle, and, thus, blocks the stimulation of vasculature hypertrophy, inflammation, fibrosis, proliferation, and vasoconstriction. Similar to all drugs acting on the renin-angiotensin system, macitentan is associated with embryo and fetal toxicity, so it should not be used in pregnancy and has special precautions that must be followed for all females of child-bearing age.

Macitentan mechanism of action

Macitentan is an antagonist/blocker of endothelin receptors. Endothelin receptors are found in the endothelial cells of blood vessels and smooth muscle. Macitentan binds to the receptors, endothelin A and B (ETA and ETB), which prevents the agonist endothelin -1 (ET-1) from binding and stimulating the ETA and ETB receptors.
