Aprocitentan, sold under the brand name Tryvio, is a medication used to treat hypertension (high blood pressure). It is developed by Idorsia. It is taken by mouth.
Aprocitentan is a receptor antagonist that targets both endothelin A and endothelin B receptors.
Aprocitentan was approved for medical use in the United States in March 2024. It is the first endothelin receptor antagonist to be approved by the US Food and Drug Administration (FDA) to treat systemic hypertension.
Medical uses
Aprocitentan is indicated for the treatment of hypertension in combination with other antihypertensive drugs, to lower blood pressure in adults who are not adequately controlled on other medications.
Adverse effects
Aprocitentan may cause hepatotoxicity (liver damage), edema (fluid retention), anemia (reduced hemoglobin), and decreased sperm count.
Contraindications
Data from animal reproductive toxicity studies with other endothelin-receptor agonists indicate that use is contraindicated in pregnant women.
Mechanism of action
Aprocitentan is an endothelin receptor antagonist that inhibits the protein endothelin-1 from binding to endothelin A and endothelin B receptors. Endothelin-1 mediates various adverse effects via its receptors, such as inflammation, cell proliferation, fibrosis, and vasoconstriction.
